Description
SE4206P2 is an Emerson DeltaV S-series simplex serial interface assembly with two independently configurable communication ports. Each port supports RS-232 or RS-422/485 operation, including half-duplex and full-duplex modes where applicable.

The assembly exchanges serial data between DeltaV and compatible devices using rates from 300 to 115200 baud. It supports 32 datasets in total, with 16 datasets assigned to each port, and includes the Modbus protocol for serial device integration.

SE4206P2 is used for connecting serial instruments, controllers, and other Modbus devices to an S-series system. Configure the physical interface, baud rate, protocol settings, dataset mapping, and device addressing separately for each port.
