Serial Communication Only
(original version)
( Part numbers starting with 1085- and 1086-)
The optional Serial Communication Module provides RS-232/485 serial data
using Modbus, DNP or ASCII protocols. The Modbus protocol can be configured
as Modbus RTU or Modbus ASCII and supports operation as a Master or Slave
device. It can transmit alarm status from the field contacts or receive alarms
through the protocol. The DNP protocol supports operation as a Slave device
transmitting the alarm status of the field contacts. The ASCII protocol is only
used in conjunction with the Time Stamping of Alarms Option (SER or SERFR)
continually streaming any alarm or return to normal events. When Modbus or
DNP is used with the Time Stamping of Alarms Option (SER or SERFR), it
provides the time and date of the alarms and return to normal events.
The Serial Communication Module can be configured via jumpers for RS-
232/485 communications. It can be configured via software for all Modbus and
DNP settings.
