Data acquisition system for small process control applications

A panel-mounted device, the Endress+Hauser Memograph M RSG45 Data Manager system features an EtherNet/IP update that helps plants integrate legacy 4-20mA, RTD, thermocouple and HART-based instruments into DCS-, PLC-, PAC- or PC-based control systems; the EtherNet/IP connection also allows plants to control batch start/stop activities from the control room. The data acquisition system accepts up to 14 discrete and 20 universal/HART analog inputs from process sensors, records the data internally and transmits it to a PC or control system. In case of a wiring failure, the system continues to record data on the storage device and can download it to the control system when communications are restored.
