Programmable logic controllers (PLC) are electrical devices used to control
and automate industrial processes by reading digital and analog inputs such as
push buttons, limit switches, temperature or pressure sensors, and then writing to
digital or analog outputs to power devices such as LEDs, solenoids, relays, or
motors. PLC programming
is usually done using Ladder Logic (also known as Ladder Diagram), which is a
graphical programming language, but other IEC 61131 plc coding languages such
as Structured Text can also be used depending on the PLC.
Maple Systems offers different types of PLCs to meet your system requirements, or control panel needs. Our Micro PLC is for small scale applications (Up to 36 Digital Inputs/Outputs and 2 Analog Inputs/Outputs) and our Modular PLC is expandable (up to 384 Digital/Analog Inputs/Outputs), which can be configured with any combination of modules to fit your application. Both PLC types use our free PLC programming software (MapleLogic) and easily integrate with the rest of our automation products such as our HMI/cMT products via ethernet or serial cables, using common communication protocols such as MODBUS TCP/IP or MODBUS RTU. Our PLCs easily integrate with most other industrial automation brands and SCADA system equipment if needed via common industry communication protocols.
Expandable PLCs with up to 11 additional I/O modules including Digital, Analog, PWM, HSC, TC and TRD Modules.
Up to 384 I/O points.
All-in-one PLCs feature built-in I/O and are ideal for your small-scale projects.
Up to 36 inputs and outputs, digital and analog.
Our HMI+PLC combines the touchscreen interface capabilities of an HMI and the I/O connectivity of PLCs in just one unit.
Designed to allow for the greatest customization with your choice of HMI, remote I/O, and the ability to execute PLC logic with a CODESYS project, this series allows you to accomplish all your needs.
These compact PLCs are designed for small scale use when simplicity and affordability merge. Ideal for specialized processes or incorporated into a larger system.
Our scalable PLC line was created for a wide range of applications capable of adapting to your specific needs. With 15 I/O modules to choose from - this PLC is perfect for your complex solutions.
First choose a CPU you wish to use. Unlike other PLCs, our logic controller CPUs have built in digital inputs and outputs that are fully functional without adding modules.
Then choose the expansion modules that meet your control system requirements. Attaching up to 11 modules onto one CPU.

PLCs. Reliable replacements or additions to small-medium scale control systems
at an affordable price.
Our PLCs offer position control, PWM, PID with auto-tuning, High-Speed Counter
(HSC), and more features to aid you in your control's solution.
Supervisory Control and Data Acquisition (SCADA) are systems that include various devices that allow users to monitor, control, and optimize industrial processes. SCADA systems can include different combinations of devices such as PLCs, Human Machine Interfaces (HMIs), monitors , databases, and more, to solve automation challenges.
PLCs in SCADA systems play an integral role by acting as intermediary between field devices and the connected system. PLC can receive input from sensors and send commands to actuators based on predefined logic while also sending and receiving information from other devices within the system.
A basic SCADA system that can be seen in small-medium scale operations is an HMI-PLC system. This system allows an operator to monitor and respond to the real-time status of the PLC, and the corresponding field devices, by way of the HMI's interface. In real world application this can give a water treatment operator the ability to remotely shut down a pump for maintenance, check the status of a sensor, and/or stop operation all together in the case of an emergency.
