Micro PLCs are compact logic controllers for small-scale applications that require less than 36 Inputs and Outputs and are extremely cost effective. These controllers provide high-level performance and reliability for industrial automation applications and use our free PLC programming software which utilizes easy-to-use Ladder Logic, Function Blocks, Instruction Lists, or other functions to fit your application. With advanced built-in features such as PID control, high speed counter (HSC), input filtering, and periodic interrupts, these PLCs will work for almost any project. They are DIN rail mountable and come with a variety of digital and analog configurations. Our PLCs easily communicate with our HMIs using MODBUS TCP/RTU making it easy to integrate with the rest of your equipment.
If you need more than 36 I/O points for larger projects, or require Temperature Inputs, see our Modular PLC products.

Our PLCs can function seamlessly as both native slave and master devices through Modbus RTU and TCP/IP protocols. This flexibility simplifies the setup process, automatically assigning Modbus addresses to device addresses, reducing configuration errors and time. To establish communication, connect your device, configure the channel to reference our PLC, and specify the Modbus address. You can easily verify communication status, or PLC connection, using the diagnostic LEDs located on the front panel of our PLCs.

Online PLC Editing
With our PLC software, you have the convenience of making real-time online edits to your logic without ever disconnecting from your PLC device. This powerful capability not only streamlines your programming and testing but also complements our hardware and software fault detection features.
Online editing offers several other valuable benefits, such as:
- Reduced Downtime: Perform updates and modifications to your control system quickly, minimizing downtime and ensuring continuous operation
- Rapid Troubleshooting: Quickly diagnose and rectify issues by making immediate changes to the logic during testing and production runs.
- Efficient Maintenance: Simplify routine maintenance tasks by fine-tuning logic and parameters without disrupting the overall system.
Hardware and Software Diagnosis
MapleLogic provides detailed fault and error detection, ensuring that in the event of an error, you can swiftly identify issues within your device. Detailed information is displayed about the location of the error, whether there’s an error with the PLC CPU and/or the modules, we offer guidance on potential resolutions. We’ve also compiled extensive error code tables in our help file, covering general errors and module-specific lists to aid you in your testing phase.
The front panel of each device features diagnostic LEDs that will indicate anytime there is an error. Special modules also have various speeds of LED blinking corresponding to different errors.
Our software further enhances your troubleshooting capabilities through a dedicated diagnostics window, where error codes and their associated reasons are displayed. If you’re using our Modular PLC, all attached modules are listed with any associated error codes.
We provide free U.S Technical Support, ensuring you have all the diagnostic resources and help to create your unique industrial solution. Call our Technical Support Team at (425) 745-3229 available Monday-Friday from 6:00AM to 4:30PM PST.
Choose from a variety of programming options including Ladder Logic (also known as Ladder Diagram), Sequential Function Chart (SFC), Industrial List (IL), and/or Function Blocks to program your control system solutions.
