3.1 The Modbus Objects
All parameters and result data can be accessed in this way. Please note that many of the
registers in the 2000 – 20FF range require a local backplane access cycle per register. Reading
multiple registers in this range may produce a very long response time.
Below is the preliminary Modbus Map.
3.2 Communication Profile
The parameters which are critical for communication are determined in the communication
profile. This includes the data for manufacturer's product nomenclature, for identification, or the
parameters for object mapping.
Abbreviations used in the tables:
R
= read only
R/W = read / write
W = write only (read will not be regarded as an error, but returns undefined results)
UI16 = Unsigned16 (single register)
UI32 = Unsigned32 (register pair)
Int16 = Signed16 (single register)
Int32 = Signed32 (register pair)
Float = 32 bit IEEE754 floating point (register pair)
