CLICK PLUS PLCs have been added to the CLICK line. CLICK PLUS CPUs come in three styles that offer convenient USB programming and support the IIoT standard MQTT protocol and Modbus TCP. CPU modules with a built-in Ethernet port also support EtherNet/IP communication, and serial-capable models utilize Modbus RTU. Each CPU has a slot for an optional I/O module so that you can configure the stand-alone PLC of your choice. Numerous Option Slot I/O Modules are available to add discrete I/O with high-speed capability, analog I/O, or combinations of both. Data logging allows you to track system efficiency and performance, troubleshoot reoccurring or intermittent faults, and predict future breakdowns. CLICK PLUS PLCs use the same FREE software as the original CLICK PLCs.
