The controller can be used as Modbus master ( ConF / othr / MASt = 1 ).
The Modbus master sends ist data to all slaves (broadcast message, controller
adress 0). It transmits its data (modbus adress AdrU) cyclic with the cycle time
Cycl to the bus. The slave controller receives the data transmitted by the masters
and allocates it to the modbus target adress AdrO.
If more than one data should be transmitted by the master controller ( Numb > 1)
, the modbus adress AdrU indicates the start adress of the data that should be
transmitted and AdrO indicates the first target adress where the received data
should be stored. The following data will be stored at the logically following
modbus target adresses.
With this it is possible e.g. to specify the process value of the master controller as
set-point for the slave controllers.
