The ProLinx Modbus Master/Slave to DF1 Master/Slave Gateway creates a powerful connection between Modbus Master/Slave and DF1 Master/Slave networks and devices. This stand-alone DIN-rail mounted protocol gateway provides four serial ports. each individually configurable as a Modbus or DF1 Master or Slave. The Modbus protocol driver supports Master and Slave implementations of the protocol. All Modbus serial ports are individually configurable. providing a very powerful and flexible host or device interface solution. The DEM protocol driver is designed to provide a tightly integrated communications interface between other protocols of the ProLinx platform and the Honeywell DE instruments. Compatible DE devices include a large array of field devices including pressure. temperature. metering. and many other instruments.
