Dear Friends, I have a problem in my PLC-2. Because there was a problem in one terminal of 24Vdc-output card. I put the PLC-2 on test mode then I pull out the card and input the new one. Then I switch the key to Run but all the output cards in each Rack still off while the input cards still on. Then I tried many times nothing change. After that, I switch the PLC power off but when I switch it on all the input and output cards are off. Please hope to answer me as soon as possible. I don’t know how to put it back again. Waiting your response as soon as possible.
