RS232 WIRING .................................................................................... 55 1 Overview The WI-I/O-EX modules are designed to provide I/O expansion for other products like WI-I/O 9, WI-MOD-9-E and WI-MOD-E modules. The WI-I/O-EX modules support the WI Series protocol, and communicate serially via RS232 or RS485. Configuration is done via the WI Series configuration utility. The WI-I/O-EX modules also support ModBus protocol. They may be used as a ModBus slave with any 3rd-party ModBus device, or with the WI-GTWY modules using ModBus. They support both ModBus ASCII protocol, and serial un-signed ModBus RTU, also known as “ModBus binary”. The ModBus slave address of the WI-I/O-EX is selected via two rotary switches on the bottom panel of the case. All WI-I/O-EX models provide digital inputs and outputs. Specific models provide analog inputs or analog outputs. Pulsed inputs and pulsed outputs are also available. Several modules may be connected to one master, allowing any combination of I/O types. Figure 1-1 shows a diagram of a WI-I/O-EX module with parts labelled.

Two ports allow configuration and communications on the WI-I/O-EX. The RS232 port is intended for configuration. The RS485 port allows the unit to be in a multi-drop configuration. Overvoltage protection and supply monitoring is provided to minimize the risk of failure due to faulty connections or supply surges. 1.1 Module types and features The module types and I/O are summarized in Table 1-1. WI-IO-EX Manual v1.11 Page 5 WI-I/O-EX Serial I/O Module User Manual v1.11 WI-I/O-EX -11 -12 -13 Digital inputs/outputs Up to 16 Up to 8 Up to 8 Pulse outputs 8 8 8 Pulse inputs 4 - - Analog inputs - 4 floating or 8 commoned - Analog outputs - - 8 Table 1-1: Summary of WI-I/O-EX module types and I/O. 1.1.1 Digital inputs / outputs Each digital I/O channel on the WI-I/O-EX modules can act as either an input or an output. The input/output direction does not need to be user configured. Digital inputs are suitable for voltage-free contacts, or NPN-transistor switch devices. Digital outputs are open-collector transistor outputs, able to switch loads up to 30VDC, 200mA. If you have wired an input/output channel as an input, it is recommended that you do not write values to it as an output. No electrical damage will occur if you attempt to use a channel wired as an input as an output, or vice-versa, however the I/O system will not operate correctly. We recommend that the required digital inputs be assigned consecutively from channel 1. Then use the remaining channels as digital outputs. 1.1.2 Pulsed outputs The first eight digital channels on each WI-I/O-EX module can be used as pulse outputs. The maximum output frequency is 100Hz. A pulse output on the WI-I/O-EX will output the number of pulses equal to the register value sent by the master. When the master sends a new register value, the WI-I/O-EX will output additional pulses until the output count is the same as the new value. Three register values are associated with creating each pulsed output: • The Count keeps a tally of how many pulses have been output - this is a 16-bit register and overflows to 0. • The Target is set by the master, and is the trigger for pulses to be created. The digital channel outputs pulses until the Count value reaches the Target value. If the Target register is set to 0, the pulses stop and the Count register is cleared. • The Update Time is the interval in which the WI-I/O-EX expects to receive updates to the Target value. The module will output enough pulses for the Count Page 6 February 2010 WI-I/O-EX Serial I/O Module User Manual v1.11 to reach the Target within the update time. The output pulse rate is determined by the update time, and the difference between the count and the target. If the calculated pulse rate is more than the maximum rate (100Hz), the WI-I/O-EX will output pulses at the maximum rate. At the end of the update time, the count value will be less than the target. The WI-I/O-EX will then calculate the new required pulse rate for the next update period, based on the difference between Count and Target values. If the calculated pulse rate is greater than around three times the maximum rate, pulses are not output. The Count value will be set to the value of the Target without any pulses output. Pulses will be output again when the calculated pulse rate falls within the maximum possible rate. 1.1.3 Pulsed inputs The first four digital channels on the WI-I/O-EX-1-S-11 module can be used as pulsed inputs. The maximum input pulse frequency is 1 KHz. The pulse input channel calculates two register variables, each of which can be read by the master. • • The Pulse Count is a count of the pulses detected on the channel since the WI-I/OEX powered up. The pulse input counts are 32-bit values (2 x 16-bit registers, a low and a high register), and wrap around to zero on overflow. The Pulse Rate is a measure of the rate of pulses detected on the channel. The pulse rate value is decimal 16,384 (hex 4000) for zero rate and decimal 49,152 (hex C000) for the maximum rate configured by the user. These zero and maximum values are the same as 0% and 100% used for analog values. (See section 5.4 for hex to decimal conversion.) The maximum pulse input rate is set during configuration. The value is in pulses per minute and is limited to 60000 (1 KHz), the maximum rate capable of the module. 1.1.4 Analog inputs The analog inputs on the WI-I/O-EX-1-S-12 can be connected as either grounded singleended inputs or as floating differential inputs. The WI-I/O-EX-1-S-12 has eight grounded inputs or four floating inputs. • Grounded single-ended inputs connect between the AIN terminal and the GND terminal. • Floating differential inputs each take up two terminals. There are four differential pairs on the WI-I/O-EX-1-S-12: [AIN1-AIN2], [AIN3-AIN4], [AIN5-AIN6], [AIN7AIN8]. For example, the first input is connected to terminals AIN1 (positive) and AIN2 (negative). WI-IO-EX Manual v1.11 Page 7 WI-I/O-EX Serial I/O Module User Manual v1.11 The two types of input cannot be mixed - all inputs must be either “grounded” or “floating”. Inputs can also be selected as mA current, or voltage input - all inputs must be the same, either all current or all voltage. The scale of each analog input is chosen during hardware configuration, with scale options as follows: Voltage input scale options: [0 to 5V], [0 to 10V], [1 to 5V] Current input scale options: [0 to 10mA], [0 to 20mA], [4 to 20mA] For compatibility with E-Series modules, 4-20mA current is recommended. See section 4.4 for more information on compatibility. The values on the analog input are decimal 16,384 (hex 4000) for minimum signal (0%) and decimal 49,152 (hex C000) for maximum (100%). The analog channel will measure over-scale, up to 150% which will have value 65,536 (hex FFFF). For 4-20mA signals, the channel will measure under-scale down to 0mA which has a value of 8,192 (hex 2000). (See section 5.4 for hex to decimal conversion.) The WI-I/O-EX-12 provides a 24V analog loop supply (“ALS”) for powering analog loops. 1.1.5 Analog outputs The WI-I/O-EX-1-S-13 has eight analog output channels and can be configured to output voltage or current. For current signals, “source” or “sink” can be selected. The scale of each analog output is specified during configuration, with scale options as follows: Voltage output scale options: [0 to 5V], [0 to 10V], [1 to 5V] Current output scale options: [0 to 10mA], [0 to 20mA], [4 to 20mA], source or sink • • • Voltage outputs are measured with respect to the ground terminal. Current source outputs are measured with respect to the ground terminal. Current sink outputs are measured with respect to the 24V “ALS” terminal. Writing to the output register by the master produces the analog output. Minimum to maximum signals (0 – 100%) are produced by register values from decimal 16,384 to 49,152 (hex 4000 - C000). (See section 5.4 for hex to decimal conversion.) The analog channel can output over-scale, up to 150% corresponding to register value 65,536 (hex FFFF). For 4-20mA signals, the channel can output under-scale down to 0mA from a register value of 8,192 (hex 2000) or less. Note that the over-scale output is limited by the maximum levels capable of the WI-I/O-EX module (12V or 24mA). Page 8 February 2010 WI-I/O-EX Serial I/O Module User Manual v1.11 1.1.6 Communications The WI-I/O-EX modules have two communication ports: RS232 and RS485. The RS485 port communicates using E-Series protocol. Both ports support ModBus protocol. The RS232 port is intended for configuration. The RS485 port is intended for normal operation and can be used in a multi-drop setup. There are two address switches on the base of the module. Setting both address switches to 00 configures the module to use E-Series protocol on the RS485 port. When the switches are set within the range 01-99, the module uses ModBus protocol on the RS485 port, with the ModBus address defined by the switches. Whenever these address switches are changed the unit should be reset by disconnecting power. When using E-Series protocol, the port settings are fixed at 9600 baud, 8 data bits, no parity, 1 stop bit. The ModBus communications settings are configurable as follows: ModBus type: RTU, ASCII with 8 data bits, ASCII with 7 data bits. (Note that the configuration software only supports ModBus RTU. A ModBus Master can select ASCII protocol by writing to the appropriate register. See Appendix A.) Baud rate: 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 76800, 115200 Parity: none, odd, even Stop bits: 1 or 2. The modules are fitted with a termination switch for the RS485. Set this switch only on the last module in a multi-drop RS485 configuration. The WI Series software is used to configure the WI-I/O-EX modules as part of a network. The hardware set-up for items such as expected pulse rates and analog signals is also available through this software. When used as a ModBus-only device, stand-alone configuration software (cfg_WI-I/OEX_Vx.xx.exe) is available to set up the modules. All required software may be downloaded from the Weidmuller website (http://wireless.weidmuller.com). WI-IO-EX Manual v1.11 Page 9 WI-I/O-EX Serial I/O Module User Manual v1.11 2 Installation All connections to the module should be SELV only. Normal 110/220/240V mains supply should not be connected to any input terminal of the module. 2.1 General installation Several WI-I/O-EX modules may be connected to one master via RS485 multi-drop connection as shown in Figure 2-1. Ensure there is good grounding between the WI-I/OEX units and the master. A 2.5 mm2 / 12 gauge earth wire is recommended. Master WI-I/O-EX WI-I/O-EX WI-I/O-EX Figure 2-1: Several WI-I/O-EX units connected to a master. 2.1.1 Power Connection The WI-I/O-EX modules require a 10.8-30 VDC ** power supply. This is supplied to the 4-way connector, shown in Figure 2-2. B A - + Figure 2-2: Power and RS485 connector. Connect 10.8-30 VDC** to + and earth to -. Connect RS485 to B and A. ** Model Dependent. Check rear label for actual operating voltages 2.1.2 Address Switches The address switches are found on the bottom panel of the module, as shown in Figure 2-3. If you are using the WI-I/O-EX module with other modules WI-I/O 9, WI-MOD-9-E and WI-MOD-E modules), the address switches must be set to “00”. This enables ESeries protocol mode. If you are using a ModBus Master device, ensure each WI-I/O-EX connected to the same ModBus master has a unique ModBus address. Note that the module must be reset after changing the address switches. Page 10 February 2010 WI-I/O-EX Serial I/O Module User Manual v1.11 You can connect to an WI-GTWY-9-MD1 Module using either MODBUS protocol or ESeries protocol. E-Series protocol is easier to set up, and we recommend using this protocol for most applications. x10 x1 Figure 2-3: Address switches. The address shown is 01.

WI-IO-EX Manual v1.11 Page 11 WI-I/O-EX Serial I/O Module 2.2 User Manual v1.11 Signal Connections All connections to the module should be SELV only. Normal 110/220/240V mains supply should not be connected to any input terminal of the module. 2.2.1 Digital Inputs (and Pulsed Inputs) The WI-I/O-EX-1-S-11 supports 16 digital signals, and the WI-I/O-EX-1-S-12 and WII/O-EX-1-S-13 support 8 digital signals. Additionally, digital inputs DIO1-4 on the WII/O-EX-1-S-11 operate as pulse inputs. Digital output signals share the same terminals as the Digital input signals, marked DIO18, and DIO1-16 on the WI-I/O-EX-1-S-11 module. A digital input is activated by connecting to EARTH, either by voltage-free contact or by a transistor switch. Refer to Figure 2-5: WI-I/O-EX Module V+ V+ DIO1 Voltage-free contact DIO2 Transistor switch device EARTH V- Figure 2-5: Connection of digital inputs. Page 12 February 2010 WI-I/O-EX Serial I/O Module User Manual v1.11 2.2.2 Digital Outputs (and Pulsed Outputs) The WI-I/O-EX-1-S-11 supports up to 16 digital outputs, shared with the digital input function on the same terminals. The WI-I/O-EX-1-S-12 and WI-I/O-EX-1-S-13 both provide 8 digital output signals. These signals are marked DIO1-8, and DIO1-16 for the WI-I/O-EX-1-S-11. On all WI-I/O-EX modules, DIO1-8 can also operate as pulsed outputs. When active, digital outputs provide a transistor switch to EARTH. To connect a digital output, refer to the diagram in Figure 2-6. A bypass diode is recommended to protect against switching surges for inductive loads such as relay coils. WI-I/O-EX Module DIO1 DIO2 DC Load + Max 30VDC 0.2A V- EARTH _ Figure 2-6: Connection of digital outputs. Note that digital outputs will only switch DC circuits, with maximum voltage 30VDC. 2.2.3 Analog Inputs The WI-I/O-EX-1-S-12 provides eight grounded single-ended or four floating differential analog inputs. These provide measurement of voltage signals (0-10V) or current (0-20 mA) signals. An internal 24V analog loop supply (ALS) is generated for current loops. Refer to Section 4.4 for detail on configuring single-ended, differential, current-mode or voltage mode inputs. WI-IO-EX Manual v1.11 Page 13 WI-I/O-EX Serial I/O Module User Manual v1.11 2.2.3.1 Grounded Single-Ended mA Inputs Single-ended current inputs allow twice as many inputs as the differential mode. This mode is useful when the sensor loop can be grounded to the WI-I/O-EX module. Devices may also be powered by the 24V supplied by the WI-I/O-EX. Refer to Figure 2-7: Loop powered sensor - + WI-I/O-EX Module ALS +24V AIN1 AIN2 Externally powered sensor + - AGND V- Figure 2-7: Connection for single-ended current inputs.

This allows the input to be connected anywhere in the current loop. Common mode voltage can be up to 27VDC. Up to four loops can be connected, to terminal pairs [AIN1-AIN2], [AIN3-AIN4], [AIN5-AIN6], [AIN7-AIN8] - the former terminal is positive and the latter negative.

WI-IO-EX Manual v1.11 Page 19 WI-I/O-EX Serial I/O Module User Manual v1.11 3 Configuration Use the WI Series Configuration utility to configure the WI-I/O-EX module to communicate to WI-I/O 9, WI-MOD-9-E and WI-MOD-E modules. - If you want to communicate using ModBus, then simply set the address using the address switches on the bottom of the module. Refer to section 2.1.2 for details on setting the address switches - Ensure the Address switches are set to “00” for E-Series protocol mode. Refer to section 2.1.2 for details on setting the address switches. The WI Series Configuration utility allows you to configure systems consisting of a mixture of Module types. You can download this software from the Weidmuller web site at (http://wireless.weidmuller.com) 3.1 Add a radio module to connect the WI-I/O-EX to the radio network. To configure a Serial module you must first create configuration for a radio module – For example a WI-I/O-9 module. This is the radio module you plan to connect the serial module to. - 3.2 Refer to your radio module user manual for an explanation on how to create the radio module configuration. Add the Serial Module Once you have created the new radio module configuration, you can add the serial module. Select the new radio module that you want to connect the WI-I/O-EX serial module to, and select the “Serial Units” item. Select “Add a new Serial Unit” to create the new configuration, or select “Load a New Serial Unit” to load the configuration from an existing module. See Figure 3-1. Page 20 February 2010 WI-I/O-EX Serial I/O Module User Manual v1.11 Figure 3-1: Configuration of WI-I/O-EX modules using Configuration Utility. When you select “Add a new Serial Unit” you will need to select the unit type. Select the correct module type here. Figure 3-2: Select the unit type. WI-IO-EX Manual v1.11 Page 21 WI-I/O-EX Serial I/O Module User Manual v1.11 Finally, you will be prompted to select the module address. You can choose to allow the configuration software to select an unused address for you, or you can select the module address manually. - Serial Module address must be in the range 96 to 127. - Every serial module that is connected to the same radio module needs a separate address. - You can use the same address on two different serial modules if they are connected to different radio modules. Figure 3-3: Select unit address. Once you have added the new module you can configure it in the same way as for 105 series modules. For more information on configuring these modules using the WI Series software, refer to the WI-I/O-9 user manual. Page 22 February 2010 WI-I/O-EX Serial I/O Module User Manual v1.11 4 Hardware Configuration Hardware Set-up allows the WI-I/O-EX hardware function to be adjusted to suit the application. To configure the hardware settings, you need: - Access to the DIP switches under the Analog Configuration Panel (refer Figure 1-1: WI-I/O-EX unit with significant parts labeled.) - Configuration Software to run on your PC. Configuration of the WI-I/O-EX modules is performed by either the dedicated WI-I/OEX configuration software (cfg_WI-I/O-EX_Vx.xx.exe), or by the WI Series configuration software (from the Utilities / Advanced - SXM menu). 4.1 Connecting to the WI-I/O-EX module To use the configuration software, perform the following steps: • Connect the WI-I/O-EX to the PC COM port with a standard serial cable (straightthrough, DB9 female to DB9 male.

Figure 4-3: Pulsed outputs setup page for a WI-I/O-EX-11. The pulsed outputs are available on all models. Clicking the button Read from WI-I/O-EX will read the pulse out update times from the WI-I/O-EX and display them on the form. The Pulse Out Update Times should be set to the approximate interval at which the WII/O-EX will receive updates to its pulse out target register. The pulse output circuitry will attempt to generate pulses at a rate that will reach the target pulse count within the update time. For example, if the ModBus master unit is configured to send the register value for the pulse output channel every 1 minute, then the Update Time should be set to 1 minute. The maximum allowed pulse out update time is 34 minutes 57 seconds. Set the update times for each channel in hours, minutes, and seconds. An update time of zero will never produce any pulses. After the update times have been set, click the Save Update Times button. The pulse output feature can be tested on the Check folder tab (refer section 5).

WI-IO-EX Manual v1.11 Page 49 WI-I/O-EX Serial I/O Module User Manual v1.11 Appendix C. Comms Recovery If the communications setting of the WI-I/O-EX has been forgotten or mistakenly set, there is a way of recovering serial communications with the WI-I/O-EX. WI-I/O-EX firmware versions 1.04 and earlier require ModScan to do this. With later firmware versions, this can be done using the configuration software, cfg_WI-I/O-EX_Vx.xx.exe. Procedure for recovering communications with recent firmware (V1.05 and later): 1. Set the ModBus address switches to 00. This fixes the communications setting to ModBus RTU, 9600 baud, no parity, and one stop bit. 2. Connect a standard (straight-through) RS232 cable to the module and the PC. 3. Start the configuration software, cfg_WI-I/O-EX_Vx.xx.exe. 4. Set the slave address to 100. 5. Ensure the comms settings are 9600 baud, no parity, one stop bit. 6. Click Connect to WI-I/O-EX 7. The module should connect successfully. 8. Choose the Comms page and change the settings to the desired parameters. 9. If the module did not connect successfully, try the steps listed below for using ModScan. Procedure for recovering communications with firmware V1.04 and earlier: 1. Set the ModBus address switches to 00. This fixes the communications setting to those specified in step 6. 2. Connect the RS232 port to the PC and start ModScan. 3. Supply power to the WI-I/O-EX. 4. In ModScan, set the following - Address: 0201 - Length: 3 - Device ID: 100 - ModBus Point Type: Holding register 5. Click Connection / Connect. 6. Choose the appropriate COM port. Also choose - Baud rate: 9600 - Word length: 8 - Parity: none - Stop bits: 1 7. Click Protocol Selection. Choose STANDARD ASCII for Transmission mode. Click OK, OK. 8. ModScan should connect to the module with no errors. 9. The registers displayed in ModScan represent the serial port settings that are used when the address switches are set to other than 00, as follows: Page 50 February 2010 WI-I/O-EX Serial I/O Module Address 40201 40202 40203 User Manual v1.11 Description Serial port transmission mode Serial port baud rate Serial port parity and stop bit 10. Use the tables below to work out the current communications settings, or write to the registers using ModScan to change the settings to the desired values. Note that the module transmission mode should be set to ModBus RTU.

Once the new comms setting are correct, be sure to change the address switches back to a non-zero setting for normal operation.
