BMS Communication 5.5.7
The BMS Comm menu is used to set up parameters to
allow a Building Management System (BMS) to interface
with the controller. The unit may be connected to a BMS
for monitoring and control of data points using a multitude
of different serial communication protocols.
When BMS communication is utilized, the controller must
be equipped with an expansion card designed for one of a
variety of serial communication protocols available.
A RS-485 serial port is available for Modbus or BACnet
MS/TP protocols and a 10BaseT port is available for
TCP/IP based protocols such as BACnet over IP, BACnet
over Ethernet, SNMP or HTTP.

If multiple Ultra-Series controllers are connected to a BMS,
each controller must be configured with a unique address
for BMS communication. This is done by programming the
serial interface port from a lap top. Contact STULZ Product
Support for assistance (see Section 9.0).
5.5.7.1 Direct BMS Control
The controller may be configured to accept proportional
analog signals that mimic sensors. The controller will act
on that signal whether it comes from a real sensor or a
BMS analog output. Refer to Appendix A for the Ultra-
Series controller BMS parameters.
5.5.7.2 BMS Set-up
The following menu screen is accessed from the
Service>BMS COMM screen to set-up the parameters for
a BMS interface to monitor controller operation for the
serial-based networks such as BACnet MS/TP. Units using
the BACnet over IP, BACnet over Ethernet, or HTTP
protocols do not need to change anything in this menu
loop.
The BMS address and baud rate have meaning only on
RS-485 networks and with the serial protocols of Modem,
Modbus RTU, Commission, and Carel. The baud rate is
fixed for BACnet. Systems utilizing a 10BaseT interface
should use the defaults of address 1, baud rate 19200,
and protocol BACnet.
If the mode selected uses a BMS supplied signal via the
communications interface (modes 1, 3 or 5), the loss of
BMS active (which is held true as long as the toggling of
the keep alive is switched between 1 and 2), will simply
cause the system to shut down and display “Off by
Network”.
The general procedure is to set up variables like return
humidity/proportional control and then toggle the value (1
or 2) to the BMS "keep alive" address.
For further details on utilizing BMS control, contact STULZ
Product Support (see Section 9.0).
