CX programmer timer

Hello everybody,

I am trying to make 3 types of timers in CX programmer which's value can be set on an NB panel. The first type uses seconds, I don't have any problem with it. The second type uses minutes and the third type uses hours. My question is that how can I set the BCD timer to read minutes and hours as the preset value? I was thinking to make a simple multiplication but then the value would be too big. Lets say I want to set 100 hours as the preset value. Then it would be 100*60*60*10 which is way too big value.

The used plc is CJ2M CPU 33 and the NB panel is TW01B

You can use the clock bits as inputs to a counter and make a timer with minutes and hours.
Section 6-23 Clock Pulses of the above manual.
Take the 1 minute pulse into a self resetting counter set for #0060. When the counter done bit is complete then use this bit (1 hour) into another counter.

The above link uses a CP1H but the programming is similar.

Hope this helps you out.
Regards,

That works but you risk being off by almost 1 minute depending on when you started the timer in the 1 minute clock period pulse of the PLC.
If you change counter to seconds and use 3600 as the counter preset you may be off by almost 1 second.

try this maybe ok maybe ko

Example here. Still will be off by a few seconds but pretty accurate.

Thank you for the help guys!

Especially for the sample programs, it solved my problem.
