TEMPERATURE CONTROLLER INFORMATION
MODBUS Communication information (Eurotherm 2408)
NOTE:
The Eurotherm 2400 Controller supports the MODBUS RTU mode of
transmission. The default settings are as follows: 9600 Baud Rate,
one start bit, eight data bits, one stop bit, & no parity bit.
IMPORTANT NOTE:
All Modbus addresses specified in this manual are written generically
in 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 And 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.
