This document should be read in conjunction with the DLC bulletin. MODEL NO. GENERAL DESCRIPTION The Model DLCN, Dual Loop Controller with DeviceNet, has a similar feature set and specifications as the standard Dual Loop Controller. The DLCN operates as a DeviceNet Slave, providing a connection to a standard DeviceNet network. Once a valid MAC ID and Baud Rate have been established, the supported attributes (see table: DLCN DeviceNet SUPPORTED ATTRIBUTES) can be accessed by a Master, providing control and status functions for each PID loop. The DLCN can also be fully programmed via the built-in RS485 communications port using our Windows® based RLCPro configuration software (refer to the DLC bulletin). DLCN In addition, the model DLCN can be used as a simple analog data acquisition device for monitoring T/C's, RTD's, voltage and current over a DeviceNet network. DESCRIPTION PART NUMBER Dual Loop Controller, w/ 5 Pin Male M12 connector DLCN0001 Dual Loop Controller, w/ 2 analog outputs, 5 Pin Male M12 connector DLCN1001 Dual Loop Setpoint Controller, w/ 2 analog outputs, 5 Pin Male M12 connector DLCN1101 Dual Loop Controller, w/ COMBICON screw flange connector DLCN0011 Dual Loop Controller, w/ 2 analog outputs, COMBICON screw flange connector DLCN1011 Dual Loop Setpoint Controller, w/ 2 analog outputs, COMBICON screw flange connector DLCN1111 PROGRAMMING THE DLCN via RLCPro MOD/NET STATUS LED In order to program the DLCN via RLCPro, the DeviceNet bus cable must be disconnected from the unit. This causes the internal DLCN communication bus to automatically switch to the front panel Modbus programming port. When programming is complete, the unit may be attached to the DeviceNet bus, thus disabling the front panel port and enabling DeviceNet communications. The DLCN Modbus communication parameters are fixed at 19200 baud, unit address of 247, 8 data bits, no parity, RTU mode. The DIP and Rotary Switches, as described below, are used for DeviceNet settings only. The MOD/NET Status LED provides a visual indication to the operator of the current status of the DeviceNet interface. The DLCN primary power and DeviceNet power must be applied for correct LED function. What to look for: A. Startup: LED flashes Green for 0.25 sec, then Red for 0.25 sec, then Off. B. LED Off: This device is the only device on the network (waiting for an acknowledgment to its duplicate MAC ID check), or this device is not powered. C. Flashing Red LED: An I/O connection has timed out, or a recoverable error has occurred. D. Flashing Green LED: The device is functioning correctly and is waiting to be commissioned by a bus master. E. Solid Red LED: The device has encountered a non-recoverable fault, such as a duplicate MAC ID response, and has removed itself from the bus. F. Solid Green LED: The device is on line, functioning correctly and has been commissioned by a bus master. SETTING THE MAC ID and BAUD RATE The DLCN DeviceNet MAC ID is set using two rotary switches allowing the ID to be set in standard decimal notation (e.g. MAC ID = 27, SWC = 2, SWB = 7 ) from 0 to 63. (64-99 are not used.) The baud rate is set with DIP switches. The following table explains the baud rate settings. DIP SWITCH SETTING TABLE SWITCH SWA SETTING 1 off, 2 off Force 125 K baud 1 on, 2 off Force 250 K baud 1 off, 2 on Force 500 K baud 1 on, 2 on Autobaud Detect (factory default) Autobaud will match the DLCN DeviceNet baud rate to the network baud rate within 5 seconds every time the DLCN power is cycled. The DLCN must be connected to a bus carrying valid message traffic. In noisy environments autobaud may not be able to properly detect the network baud rate. In this case, manually set the baud rate as required. Note: Configuration of MAC ID and baud rate is not supported over DeviceNet. 1 DeviceNet™ SPECIFICATIONS SUPPORT CONNECTIONS POWER SUPPLY Source: Supplied by DeviceNet bus. The bus does not power the host. Voltage: 11 to 25 VDC. Current: Nominal: 40 mA at 25 VDC. Inrush: 550 mA for 5 msec at 25 VDC. Polled Command: The Polled Command produces 4 bytes of data, and is used to get, or set attributes. The device attribute is determined by the value in byte 0 of the data field. Refer to the Supported Attributes table for the appropriate value. Byte 1 determines the action: 0 = get, 1 = set. The next 2 bytes are the new attribute value for the set command. For get commands, enter 2 zeros. The data response from the Polled Command is in the format of a 2 byte hexadecimal number. For the get command (0), the response is the attribute value. For the set command (1), the response is an echo of the data input. NETWORK SPECIFICS Compatibility: Group 2 Server Only, not UCMM capable. Baud Rates: 125 Kbaud, 250 Kbaud, and 500 Kbaud. Bus Interface: Phillips 82C250 or equivalent with mis-wiring protection per DeviceNet Volume 1 Section 10.2.2. Node Isolation: Bus powered, isolated node. Host Isolation: 500 Vrms for 1 minute (50 V working) between DeviceNet and DLC input common. Bit Strobe Command: The data response from the Bit Strobe Command is in the format of a 2 byte hexadecimal number. The register that will be read using the Bit Strobe command is determined by setting Attribute 2, Instance 1, Class 100* (decimal) with a value that represents the desired attribute. Refer to the Supported Attributes table for the appropriate value. EXPLICIT MESSAGE COMMAND INSTALLATION INFORMATION Factory Settings: Baud rate: Autobaud MAC ID: 63 Strobe Register: 03h Swap data flag: Off. Get Attribute: The attribute that will be read using the Get Attribute command is determined by setting Service Code 14, Instance 1, Class 100* (decimal), and the attribute with a value that represents the desired meter attribute. Refer to the Supported Attributes table for the appropriate value. The data response from the Get Attribute Command is in the format of a 2 byte hexadecimal number. Set Attribute: The attribute that will be set using the Set Attribute command is determined by setting Service Code 16, Instance 1, Class 100* (decimal), and the attribute with a value that represents the desired meter attribute. Refer to the Supported Attributes table for the appropriate value. The data field for the Set Attribute Command is entered as a 2 byte hexadecimal number. Bus Connection - based on model chosen. See ORDERING INFORMATION, Page 1. For Connection Options, See Diagram on Page 4. COMBICON M12 1 = SHIELD 2 = V+ 3=V 4 = CAN H 5 = CAN L 3 4 5 2 1 V CAN L SHIELD CAN H V+ OTHER EXPLICIT MESSAGE ATTRIBUTES 1 2 3 4 5 Data Byte Swap: (1 byte), Attribute 1, Instance 1, Class 100* (decimal). Data is normally sent and entered as follows: DLC value = 50000 (C350h). 2 byte value sent would be 50C3. Setting the data swap value to 1 would result in the data being sent as C350. This attribute can only be set to 0 or 1, all other values are ignored. The factory setting value is 0. Data byte is saved in EEPROM memory. Note: Shield has no internal connection in the DLCN. Data Update: The DeviceNet interface is continually requesting values from the DLC main processor and updating buffer registers. As such, valid attribute values are always available over DeviceNet at the maximum bus rate.
