8 Special functions
8.1 KS90-1 as Modbus master
a
This function is only selectable with BlueControl (engineering tool)!
The KS90-1 can be used as Modbus master ( ConF / othr / MASt = 1 ). The
Modbus master sends its 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 al-
locates 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 in-
dicates 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.
