Components and Architecture - Serial Ports (RS232 and RS485)

Serial Ports (RS232 and RS485)

Overview

Ports configurable as ELN, Modbus RTU or Modbus TCP protocol.

Controller can act as Modbus master or slave through either port.

Controller can be master to slaves such as

Honeywell Operator Interface (1040, 559). Must be on 485 port. Will not work on 232 port with 232/485 converter.

Honeywell HC Designer PC software

Third party PC HMI software

Third party Operator Interface

Controller can slave to masters such as

Any Honeywell Modbus device (e.g., recorders, controllers, flame safety)

Any non-Honeywell Modbus device.

Only one master port at a time, can’t have RS232 and RS485 both as master ports.

For multiple slaves on RS232 port, a 232-to-485 converter is required.

Baud rates to 57,600

Table 2 shows the ways the two ports can be configured simultaneously.
