Additional Ethernet PLC-5 Controller Enhancement
Ethernet PLC-5 controllers support use of the 1785-RC Relay Cartridge.
The relay cartridge serves as an interface from the controller to a user-supplied
external device such as an Allen-Bradley 700P relay. When the controller is in
run mode, it monitors online ladder program edits and I/O forcing activity.
When either of these is detected, the controller opens the relay on the relay
cartridge for one second.
