“Address/Symbol” Editor: the address descriptions and symbols we entered during program development.
As with the “Rung Comments/Page Title” Editor, address descriptions and symbols can be edited, updated, added, or deleted in bulk from this editor to save time.
We will introduce three new bit instructions and how a logic branch is executed.
We will program a couple of rungs to demonstrate some common bit functions that will be used in the next example program.
These instructions can be found in the “BIT” tab of the instruction selection window.

TOF: Timer Off-delay
RTO: Retentive Timer On-delay
RES: Reset
CTU: Count Up counter
CTD: Count Down counter

Since the moto...
