What is this logic exactly. I see some writing and reading from a special function module, then some population of registers but I do not see the end result. Is there rungs yet to be shown?

I will take a look but connect to the attached link for the manual on how to create function blocks in GX Developer. (if you do not have one yet you will have to create a login for the site - it's free):

Also, in your logic what is the Special Function Module located in K0? (SFM#0)?

@kaykay79 a suggestion. The first three rungs can be modified to the sample below. This provides the same operation and saves memory space.logic.thumb.png.c9646765f2d3722ce106b9d5
