8 Special functions

8.1 KS90-1 as Modbus master

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.
