some analogue inputs are magenta in monitoring system. it means no data from PLC. and QVZ alarm blinking. we replace the related analog cards but no change
This is timeout error, I/O module not accessible......(may be wrong input access). If the cards are OK then, Restart the PLC and download the program again.
if you have EPROM , then make sure you got the latest program burnt on EPROM.
