If the data distribution board is in the passive mode, you must give it an address. This address
defines the application of the data distribution board. When you start the system for the first
time, you must push the de-init switch of the data distribution board to send its address to
the central control unit (refer to Initialization, page 178).
When you use the central control unit to erase the addresses of all units (refer to Initialization,
page 178), you must not push the de-init switch again. The central control unit remembers the
addresses of the passive data distribution boards when it is started again.
Addresses
If necessary, set the address of the data distribution board with the S8-6, S8-7 and S8-8
switches. This address is only used when the data distribution board is in the passive mode.
The address defines the application of the data distribution board.
