Hello. I have a question!!

How to reset ADD_DI? Could you explain this by Ladder not STL?

Thanks

I use a similar but somewhat easier solution.
If you set a clock byte in the processor (MB1 for example), then M1.5 will be a one second pulse bit.
Use your true condition contact, the 1 second pulse contact and then a postive edge (p) before your ADD_DI instruction.
Something like...
x.x m1.5 x.y(one shot)
---| |--------| |-----------(p)--------ADD_DI



Your jpg looks like it will count (ADD_DI) as long as the S_ODT is true which means it will increment by one every processor scan. Your results may be totally unpredictable.

Also, if yu are using a memory word, include it in the processor retained memory range as specified in the processor hardware configuration.

Hello GeneralPark,

resetting means what, set the result to zero?

Then use e.g. a NO contact in the branch of ADD_DI.EN and a NC contact (with the same tag as for the NO contact) in the branch of MOVE.EN which copies "0" to the result of the ADD_DI.

Thanks Mr. Frink

It's correctly working now. It's easy way but the beginner always meet the difficult face about everything.

Once again, Thanks for your kindness!

Have a nice day
