Communication object vs. Register
All the data intended for communication has its representation as communication objects in the
controller. The communication object is represented by the n-byte array in the controller memory and
identified by the unique 16-bit communication object number. The register, according to Modbus
communication protocol, represents a two-byte data and in communication functions is referenced by
16-bit register address. Further in the description of communication functions the communication
object number will always be used as a register address and length of the communication object
will be expressed by number of registers. Just one communication object can be read or written
by one communication function.
NOTE:
To obtain communication object numbers it is possible to download the actual controller description
on-line from controller or from (ail) archive and use “export data” function from LiteEdit software.
