CLICK PLUS C2-NRED and C2-OPCUA option slot modules

Two specialty modules have been added to the CLICK PLUS PLC range: the C2-NRED and C2-OPCUA option slot modules.

The C2-NRED module provides an industrial interface to Node-RED, a popular open-source tool for developing IIoT applications. The C2-OPCUA module provides connectivity using the OPC UA communication standard. Both modules are designed to expand the communication capabilities of CLICK PLUS CPUs without affecting the performance of the main controller.

The C2-NRED includes a microSD card slot, a Micro-B USB port and an Ethernet 10/100Base-T (RJ45) port. The C2-OPCUA features a Micro-B USB port and an Ethernet 10/100Base-T (RJ45) port. Both modules can be used with all CLICK PLUS PLCs.

The modules are suitable for industrial applications where reliable communication between plant-floor PLC systems and higher-level IT or SCADA environments is required. Typical applications include manufacturing, utilities, infrastructure and remote monitoring installations.

The C2-NRED module includes its own processor and provides direct access to PLC memory, enabling data exchange with external systems through low-code Node-RED flows. It also supports custom JavaScript programming for more complex logic. The C2-OPCUA module enables seamless integration with a wide range of OPC UA-enabled devices and systems, allowing CLICK PLUS PLCs to participate in standardised data-sharing architectures. Both modules offer streamlined integration while maintaining PLC performance.
