About 1785-ENET
This Ethernet interface module has One (1) RJ45 Port supporting Ethernet TCP I/P protocol. It supports data transmission speed of 10/100 Mbps with auto-negotiation capability. It has built-in status indicators such as STAT, 100M and 10M. The STAT indicator display the module’s Ethernet link activity. 100M depicts connection to a 100 Mbps network while 10M pertain to link activity in 10Mbps network.
the Ethernet communication interface directly attaches to the 1785 backplane via a 1771 PLC5 chassis. It is compatible for use with Enhanced PLC5 controllers, PLC5 controller with ControlNet communication port, and PLC5 controller with Ethernet communication port as well. Installing this Ethernet interface module together with a PLC5 Ethernet controller enables dual link capability.
