NOTE
The points “Reg Outlet Temp” and “Net Direct Drive” are disabled as
default in the Modulex programs. This is suitable when a BMS II is
controlling the Modulex boilers. If there is no BMS II and the boiler is to be
directly controlled by the XPC, these points must be enabled usingthe
“AppLoader” program and the program cable.
IMPORTANT
All Modbus addresses specified in this manual are written generically in
hexadecimal/decimal format. However, many Building Automation Systems
utilize another form of addressing where:
• 40001 is added to the generic address for a Holding Register
address.
• 30001 is added to the generic address for an Input Register
address.
Check the addressing scheme being used by the BAS interfaced to the
XPC Gateway.
