1131 Complete procedure for replacing the card assembly?
Thread Content
There is a 3625 card on the ITCC rack that occasionally reports faults; checks of other circuits show no problems. Technicians from the manufacturer came to assist, stating that the quality of the 3625 cards is unstable and suggesting an upgrade to 3664 cards. The problem is that there is now a 3664 card available as a spare, but how can this spare be installed when the PLC is shut down? What settings are required for the 1131 program? Looking for a replacement procedure that is efficient and reliable? Let’s discuss this together.
It is said that the 3625 supports triple redundancy, making it suitable for large-scale units, while the 3664 cannot fully replace the 3625. No specific specifications have been found.
