Communications Group - Honeywell UDC2800 Product Manual

Communications Group

Introduction
The Communications group lets you configure the controller with
Easyset, a mobile app that communicates through Bluetooth, and
lets a Modbus® client/master host communicate with the controller
via Ethernet TCP/IP protocol.
A controller with the Ethernet option looks for messages from the
host computer. If these messages are not received within the
configured shed time, the controller will SHED from the
communications link and return to stand-alone operation. You can
also set the SHED output mode and setpoint recall, and
communication units.
Up to 99 addresses can be configured over this link. The number of
units that can be configured depends on the link length, with 31
being the maximum for short link lengths and 15 drops being the
maximum at the maximum link length.
