5 Setting the thumbwheel
Use the thumbwheel on the front to address the wireless
modules and the extension modules.
Front module
• The role of the master and slave must be assigned in or-
der for the front modules to communicate.
– The master address is 01.
– The slave address is between 02 ... 99 (02 in our
example).
I/O extension modules
• Set the same address (e.g., 88) on both extension mod-
ules. In this way, the inputs are assigned the corre-
sponding outputs.
