Input Contact placement on ladder rung?
« on: March 22, 2019, 11:25:20 AM »
I am using Do-More Designer and am trying to place a contact on the right side of the rung as shown in the attachment.  I'm unable to do this in Do-More. Is there a way to turn on or off rules that dictate only contacts be placed on left and coils be placed on the right sides of the rung?

Place the output O:2/3 in a branch ABOVE the contact/coil combination. You are probably getting the 'AND above a Join' error.

An output is a PLC's way of getting its inputs to change.

Logically it's a legal rung. Our compiler will swap the order of the first and second coils though.
