CHAPTER 5. MODBUS SOFTWARE SETUP: C-MORE &
BMS
NOTE
Section 5 provides Modbus Software Setup information for BMS
(Model 168) units only. Refer to Section 6 for Modbus Software
Setup information for BMS II and ACS units.
NOTE
The BMS includes a Modbus Pass-Thru function which permits an
EMS to monitor and configure the boilers on the Modbus network.
However, it does not permit the EMS to directly control the boilers.
This Modbus Pass-Thru feature is enabled in the BMS Field Adjust
Menu using the AIR TEMP key. Refer to BMS Manual GF-108M,
paragraph 4.3.2 and Appendix D for details.
5.1 INTRODUCTION
This Section provides the information necessary to configure the AERCO C-More Boiler
Controllers and a Boiler Management System (BMS) for operation on a Modbus Network. It also
provides the basic setup procedures to operate the C-More Boiler Controller and BMS in each
available Modbus Mode.
5.2 C-MORE BOILER CONTROLLER SETUP FOR MODBUS
OPERATION
The C-More Boiler Controller can be set up for three types of Modbus operating modes. These
modes are as follows:
• Monitoring and Configuration Only
• Modbus Direct Drive Control and Monitoring
• Modbus Remote Setpoint Control and Monitoring
The following paragraphs provide the procedures necessary to set up the C-More Boiler
Controllers for each of the above modes of operation. These procedures assume that the
required wiring connections for Modbus operation have already been accomplished as described
in Section 4.
NOTE
The appropriate password must be entered in the Setup Menu of
the C-More Boiler Controller, prior to changing any of the current
settings. For detailed information on menu items, refer to the
appropriate Operation and Maintenance Manual for the Benchmark
Series or KC1000 Series units being used.
