MicroSmart Pentra micro-PLC with web server functions includes two batteryless models. MRAM memory in the controllers means values can be stored permanently. They can be configured to communicate with WindLDR software, IE/Firefox/Safari web browsers, WindSRV OPC software, HG operator interface and Modbus TCP, all at the same time. They’re available in two CPU models with 12 I/O configurations (eight DC inputs and four transistor sink or source outputs).
