4.4 Address for bus communication
IO 113 can communicate with control systems via a
bus connection. For the purpose of bus
communication, IO 113 is slave. As a control system
must be able to identify the slave units with which it
communicates, the IO 113 modules must have
unique addresses. An address between 32 and 231
can be selected. By default, the address is set to
231.
When an SM 113 is used together with an IO 113 as
a pair, SM 113 is slave. In one control system, a
maximum of seven pairs may be used. Each IO 113
must be identified by a unique address, configured
by means of DIP switches 3, 4 and 5. See the below
table.
Another way to set the unique address of an SM 113
in the control system is by bus. In this case, DIP
switches 3, 4 and 5 must be toggled to OFF.
