LPB device address

The device address and the segment address are used as destinations in the bus
system (similar to a postal address). To ensure communication, each device must be
correctly addressed.
1. Press the operating line selection buttons to select operating line 140.
2. Press the + / - buttons to enter the device number.
Setting range
0...16
Entry of the device address is especially important when using combinations of units, or
in a system. The addresses classify the controllers within a segment.
Entry:

0 Standalone
1 Master (LPB)
2...16 Slave (LPB)
The device addresses should be assigned in consecutive order in accordance with the
controllers connected. It is not permitted to assign an address several times within a
bus segment, since this would lead to communication errors. Each segment must have
a device as a master (address 1).
For more detailed information about the addressing of devices in a system, refer to
"Local Process Bus (LPB), Basic Documentation, System Engineering" (document no.
CE1P2370E).
