PLC Training

Are you new to PLC programming or do you need more support with our PLC programming software (MapleLogic)? Our catalog of tutorials, sample PLC projects, and tech notes were created to help you learn the tools needed to solve various control problems.

Get introduced to the tools, programming, and hardware used throughout the automation industry. Work alongside our tutorial videos to learn the basics of PLC hardware and PLC software while becoming more proficient in programming by creating your own solutions to common automation problems and testing them in our PLC simulator without the need to have physical hardware.

Crash Course: Digital IO

Skills you’ll gain: How to wire your input and output devices, configure your PLC, and how to read and write to a register

Crash Course: Timers

Skills you’ll gain: Understanding of various timers, how to implement timers, and when certain timers should be used

Crash Course: Data

Skills you’ll gain: What data types are available, how to address memory, and simple ladder logic

PLC Communication

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.

Communicate over Etherent (10/100 Mbps)

  • Modbus TCP/IP Slave

Communicate over Serial RS-232

  • Modbus RTU Master and Slave

Communicate over serial RS-485

  • Modbus RTU Master and Slave
  • Multi-drop available (up to 32 units)
  • Resistance switch option to improve communication quality

Available Protocols

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.
