Why does my PLC boot into STOP mode?

If your PLC powers on, and indicates that it’s in “stop” mode via the LEDs on the unit, but the “error” LED is off, then it’s likely that the physical “run/stop” switch on your PLC…

How to Transfer a MapleLogic Project

These instructions detail how to transfer a MapleLogic project file to a different directory or device.  In order to open your MapleLogic project properly after the transfer, you will need the *.PLC file, as well…

What is MapleLogic Simulation Mode?

MapleLogic has the ability to run a project file in simulation mode for testing purposes. Simulation mode uses the computers loopback address of 127.0.0.1. The loopback address connects to the local computer and simulates PLC…

What are the available registers in MapleLogic?

In MapleLogic registers store data used for control logic and operations. They hold values such as integers or bits. Registers are essential for monitoring inputs, and controlling outputs. Common register types include discrete, word, timer,…
