PLC Signal Routing

The following diagram provides you with a detailed view of how the video interface accepts signals from 

various function blocks, routes them through the signal routing block, look-up table (LUT), enhanced 
function block, and finally to the external outputs.

Important:

 While this diagram shows a certain number of timers and signals, this diagram is provided as an example. 

For the timers and signals available for your video interface, see the user guide that accompanies it. User guides are 
available on the Pleora Support Center at 

supportcenter.pleora.com
