one Digital output module has Dameged I replace with a new one
after that the analog output which control the frequncy of many inverters was STOP & this is the problem.

Did you replace the digital output module with the exact same type?
Did you put the output module in the exact same order?
If not, the addressing is different for the whole system.

I was reading the operation manual of CQM1H (catalog no. W363-E1-2), Section 6 describe the DIP switch settings of CQM1 PLC. I found out that there is DIP switch setting (pin 7) that determine the operation mode of CQM1 upon power up of the PLC. base on the manual, if no device was connected to the PLC (for example hand-held programming terminal) and pin 7 is off on power up the PLC will be in PROGRAM mode but if pin 7 is on, on power up the PLC will be in RUN mode.
If the PLC is in PROGRAM all outputs are disabled.
see the link below for your reference
