Figure 1: System Architecture—Modbus RTU Master, Modbus TCP Client, and Modbus RTU over Ethernet.

Notes on System Architecture

The Modbus 250 Driver as RTU Master, Modbus TCP Client, and Modbus RTU over

Ethernet (Figure 1) supports the following:

● BACnet MS/TP or BACnet/IP ALN on Firmware 3.

If the driver is on a BACnet MS/TP network, you can use a standard field panel

with Firmware Revision 3.1 or later as a router to connect to a BACnet

workstation. Do not use an Integration Driver as the router.
