Endress+Hauser’s Memograph M RSG45 data manager is a data acquisition system for small process control applications and has EtherNet/IP capability. It can integrate legacy 4-20mA, RTD, thermocouple, and HART-based instruments into a modern control system. The RSG45 can integrate up to 20 individual instruments into an EtherNet/IP environment using a single standard Cat 5 cable. The EtherNet/IP connection also allows a plant to control batch start/stop activities from the control room. The RSG45 is able to accept up to 14 discrete and 20 universal/HART analog inputs from process sensors.  It can then display this sensor data on its 7-inch multicolor TFT screen, records the data internally, performs math calculations and alarm checks, and transmits the data to a PC or any control system via EtherNet/IP, Ethernet, RS232/485, Modbus, Profibus DP or Profinet digital communication links.

Data can also be stored to external memory plugged into the USB or the SD port. In case of a wiring failure, the RSG45 continues to record data on the storage device, and can download this data to the control system when communications are restored. The RSG45 has a HART gateway function that allows direct access from the PC configuration software to the field devices connected to the unit without the need for an additional HART modem or loop interruption. This allows configuration of the field devices to be done easily and quickly from the control room. It is a panel-mounted device with an optional 316L stainless steel front panel and touchscreen that fulfills hygienic requirements in the food and beverage and life sciences industries.
