Digital Output Module DO562, Coil doesn't get on with NO variable. Please help,its urgent.
Hello Everyone, I am new to codesys programming and working project with PM554-ETH. I have created event based 4 tasks based on different process required by machine.
The problem I am facing now that Digital output does not get on when variable "TEST_IP" goes ON, but for NC contact "test1" it gets ON because of direct contact with power. I have attached image of ladder for better understanding.
Also, why when I force a input "TEST_IP", it show half blue rectangle and not like NC contact "test1"? is it the reason?

Hi,
Nothing attached in your post? Did you connect +24VDC to terminal 19 +L and 0VDC to terminal 20 M of DO562?

Yes sir, I connected +24DC and 0VDC. But even when I do simulation in codesys, no coil in energizing in my program even when corresponding variable goes high.

Hi,
I think in simulation mode the outputs will not energized. Try to write TRUE or BLINK output, connected to your output, download, go online and run the program
