Purpose
MachMotion’s CNC software, Mach3, is designed to serially communicate with ModBus devices. For
extra I/O or tool changers, PLCs can be easily interfaced with our control.
In this manual you will learn how to setup the ModBus protocol to communicate with your PLC. Also,
you will examine the addressing scheme
and the I/O mapping used to easily a...

2.1.1 Ladder Logic
Ladder logic is the main programming method used for PLCs. As mentioned
before, ladder logic has been developed to mimic relay logic. The decision to use the ... ladder logic will be scanned
(solved) using the stored values - not the current values. This is done to prevent logic
problems when inputs change during the ladder logic scan. When the...
