Addressing
When mounted and wired the PCB can be addressed via the address-
ing unit AC1144 using the cable (E70032).
Assign a free address between 1A/1B and 31A/31B. At the factory the
address is set to 0.
If a slave with the extended addressing mode is used in combination
with a master of the first generation (version 2.0), the parameter P3
must be 1 and the output bit D3 must be 0*. The output bit D3 and
the parameter bit P3 must not be used.
If a slave with the extended addressing mode is used in combination
with a master of the first generation (version 2.0), an address between
1A and 31A must be assigned to this slave.
