Maple Systems PLCs are the go-to PLC when you need a rugged, affordable, straightforward PLC solution. Easy to program, quick to deploy, in stock and ready to ship.
PLCs are industrial digital computers designed to execute real-time control operations in manufacturing and process automation environments. HMIs are graphical user interfaces that control and interact with industrial automation systems. HMI+PLC combinations are devices that consolidate both control processing and operator interface functions within a single compact unit.
Yes. The Maple Modular can add PWM capability by connecting a Pulse Width module that includes 12-CH PWM outputs and 20 additional digital outputs with up to a 4000 Hz duty cycle.
Yes. All Maple Systems PLCs come with 2 channels dedicated to high-speed count, including both the Maple Micro and Maple Modular series PLCs. Maple Modular PLCs can be expanded to have more than 2 HSC channels by adding high-speed count modules as needed.
Maple Systems PLCs are compatible with any HMI that supports the industry-standard Modbus TCP/IP or Modbus RTU protocols. This includes every Maple Systems HMI that we sell, as well as…
Maple Systems PLCs support Modbus TCP/IP and Modbus RTU communications. Modbus communications do not require any licensing or proprietary software to use which means our PLCs can communicate with hundreds of devices, with no extra costs
In computer networking, a node is any physical or virtual device that is part of a network. This includes hosts like HMIs and PLCs, as well as devices that help manage network traffic, such as routers, switches, and access points.
EtherNet/IP (Ethernet Industrial Protocol) is an industrial networking protocol that operates over standard Ethernet infrastructure. EtherNet/IP is an open and standardized protocol governed by the ODVA (Open DeviceNet Vendors Association). It uses the standard TCP/IP suite for communication but is specifically designed to handle real-time control and monitoring in industrial environments.
If your PLC powers on and indicates its in STOP mode, its likely the physical RUN/STOP switch on your PLC is set to STOP mode. You can open the hatch next to the Maple logo and flip the yellow switch to RUN mode.
Yes they all have built in block terminals except the ES1616P which needs a separate terminal block with connector. For I/O modules only the HSC Module and PWM module need…
You do not need to order the MOD-SENT01 if you don’t need the PLC to be the Modbus TCP Master device.
Yes, the ES0806R includes an ethernet port for modbus TCP slave. All the PLC’s are Modbus TCP slave natively.
Absolutely. Maple Systems PLCs can communicate with an HMI + PLC (HMC) either with or without I/O modules attached to it. A potential application would be to have the PLC…
UL indicates that the product has been tested to meet the safety standards of the United States by Underwriters Laboratories. UL adds another layer of assurance and peace of mind…
