Allen Bradley 1771-WHFB Module

Output Module Operation

When an output module physically resides in a remote chassis with respect to the owner-controller, the owner-controller sends data to the output module only at the RPI rate specified for the module. Updates are not performed at the end of the owner-controller’s tasks. Whenever the module receives data from the controller, it immediately multicasts the output commands it received to the rest of the system. The actual output data is echoed by the output module as input data and multicast back out onto the network. This is called output data echo.
