Our Modular PLCs replace the EX PLC Series and I/O modules
The MLC PLC series and MLE I/O Modules were discontinued several years ago. They’ve been replaced with our Modular PLC series and their I/O Modules.

Need help planning the upgrade? Tell us how this product is used in your system and we will work out the right path forward, and what stays the same in your existing project.
FREE User Friendly PLC Software
Download our free, powerful PLC configuration software. Using your preferred programming language—Ladder Diagram, Instruction List, Sequential Function Chart, or Function Block—you can create your project, your way, for a one-of-a-kind control solution.

Can I pair a Maple HMI with a Maple PLC?
Yes. Our HMIs can be paired with our PLC products via Modbus RTU or TCP. The Modbus Slave driver is configured in the PLC software, and the Modbus Master driver is configured in HMI software (EBPro). Tags can be exported and imported in both directions.Software Downloads & Upgrades
