GENERAL This document describes the AC700-CUA-01 Communications Upgrade Adapter DeviceNet features supported by the EL731. Network Status LED Module Status LED 2. INSTALLATION To field-install an AC700-CUA Communications Upgrade Adapter, disconnect the EL731 supply voltage, remove the adapter-access cover, insert the adapter, and retain with the supplied screws. Apply the supply voltage. 3.1 CONFIGURATION SOFTWARE FIGURE 1. LED Indicators. TABLE 1. EL731 DEVICENET CONNECTIONS TERMINAL 1 2 3 4 5 Retaining Screws DeviceNet Interface 3. DEVICENET DESCRIPTION VCAN_L SHIELD/DRAIN CAN_H V+ 3.2 CONFIGURATION SETTINGS The EL731 supports 125, 250, and 500 Kbit/s. The MAC ID is adjustable from 0 to 63. The baud rate and MAC ID are set using DeviceNet commands or the RSNetworx Node Commissioning tool. 3.3 TERMINATION DeviceNet requires a 120 resistor at each end of the network. 3.4 POWER CONSUMPTION The DeviceNet module requires 125 mA maximum from an external 24 Vdc supply to power the driver circuits. 3.5 EDS FILE The EDS file is an Electronic Datasheet file that defines the characteristics of the EL731. It is used by configuration software such as RSNetWorx to setup the EL731 on the network and allows DeviceNet scanners to map EL731 I/O Data to PLC/PAC memory. Only one I/O Polling assembly is supported, consisting of four bytes for output and four bytes for input. See Section 4. STATE TABLE 2.
