need to slow input or recognition speed on 100md+

[Ken]

I am using the following custom function once upon startup to set some values.  My problem is that I want to increment the values one at a time or at least slow it down so that I can reach a specific integer.  The inputs are switches, and the plc is scanning so fast that I cant increment as slow as required.

Thanks in advance,
Ken

In this application using the ladder logic in combination with Custom function will work very well. You may want to check out the sample program: "SetTimCtrSV.pc5" in your TRiLOGI "samples" folder. We used 3 push button switches for you to set the value. Each time you press a button it only increment or decrement one step at a time regardless of how fast the ladder logic scan.
