The Wx100-MQTT is a powerful PLC with built-in MQTT client functions and connects to the LAN or Internet via integrated Wi-Fi. Using the RS-485 port of older machine controllers, it extracts, processes and uploads data to an MQTT server directly. It is well-suited for use in an IIoT environment. The PLC includes a built-in mini graphic display, customizable keypad and 14 base I/Os (expandable) and supports full floating-point math, TCP/IP, Modbus RTU, Modbus TCP and RS-485.
