microNCS provides Modbus RTU (RS-485) master capabilities, cost-effective distributed data acquisition and, with expansion I/O, control capabilities. One or both of the microNCS’s Modbus RTU ports can be configured to poll other RTU slaves with all of the network polling functions of a typical Modbus master. An industry-standard OPC interface delivers plug-and-play integration with popular PC-based HMI and SCADA software packages.
