Omron CQM1H-CPU51

Hi there, currently my company is using Omron CQM1H-CPU51 for machine production . I did plc program modification using TTIM (totaliziing timer) function. After I successfully transfer the modify prorgram to the cpu, I test run the program but my TTIM is not counting. I did set the dip switch no.4 to On stage but still no progress on the TTIM. Is there any thing that I missed out? Please advise. Thks.

Why? They have not been manufactured for years and are no longer supported. Tell your company to get with it and use modern PLCs. There are some examples in the manual for using TTIM is it supported in these old timers?

Recycle power?

Check your set value. Make sure that if you want a specific number to use the # infront of the number. If you do not, the PLC interprets this as a channel (register) that contains the number.
TTIM (BCD): #0000 to #9999
