PL280 Compact PLC

Compact PLC

The PL280 is a compact PLC that integrates both analogue and digital I/Os. It features a CPU based on the ARM CORTEX H7 480MHz microprocessor and is programmable with LogicLab (IEC 61131-3). The PL280 is designed as a control unit and connectivity node, offering RS485 serial (Modbus RTU), Ethernet (Modbus TCP), and CANopen communication capabilities.
The PL280 can be expanded using PLE500 I/O modules, which connect to the CPU via an internal real-time bus on a DIN rail, or with MCM260X modules for remote I/Os. It supports Industry 4.0 connectivity through the Modbus TCP protocol.
Additionally, the PL280 series can function as an I/O unit with Modbus TCP/RTU connectivity and serve as a secondary logic controller for temperature and process control. This is facilitated by the availability of analogue I/Os for temperature and 4...20mA/0...10V signals, as well as PID-Autotuning function blocks in the LogicLab programming tool.

  • Compact Design: Integrates both analogue and digital I/Os in a compact form factor.
  • High-Performance CPU: Equipped with an ARM CORTEX H7 480MHz microprocessor.
  • Programmable with LogicLab: Supports IEC 61131-3 standard programming with LogicLab.
  • Versatile Connectivity:
    • RS485 serial communication (Modbus RTU)
    • Ethernet communication (Modbus TCP)
    • CANopen communication
  • Expandable: Can be expanded with PLE500 I/O modules via an internal real-time bus on a DIN rail.
  • Remote I/O Capability: Supports MCM260X modules for remote I/O connections.
  • Industry 4.0 Ready: Supports Modbus TCP protocol for Industry 4.0 connectivity.
  • Secondary Logic Controller: Can be used as an I/O unit with Modbus TCP/RTU connectivity for secondary logics.
  • Temperature and Process Control: Features analogue I/Os for temperature and 4...20mA/0...10V signals.
  • PID-Autotuning: Includes PID-Autotuning function blocks in the LogicLab programming tool for precise control applications.
