Hi Jim

In addition to what I’ve indicated in my latest reply, your loop should be programmed in a Periodic Task as recommended by Rockwell. Your image indicates you are using the default “Periodic” timing mode, however you have not placed the loop in a Periodic Task.

When you place the loop in a periodic task the instruction will automatically use the periodic task update rate as the update time. This mode is the easiest to implement and can be used for most applications.
