I have 2 Twido TWDLCAA24DRF PLCs for our Chick Master Tray Washing Machine, However, after the connections, Output '0' doesn't turn ON on both PLCs. What's the problem?

Perform the following steps to check if the Twido outputs are working or not:
 
1) Create small application with one Digital output. (%Q0.0 ) 
2) Download the application in twido & put twido in Run mode. 
3) Check the LED status on Twido. 
4) Check the AC Power and Relay Output Wiring Schematic in the Attachments
