In addition to an RS-232 and RS-485 2-wire interface, the wireless modules support the op-
tion of directly connecting up to 32 I/O extension modules in the station structure via the DIN
rail connector.
Addressing of the wireless modules and I/O mapping of the extension modules is carried
out quickly and easily by means of the thumbwheel on the front. The yellow thumbwheel on
the wireless module is used to set the RAD ID. The white thumbwheel on the extension
modules is used to set the I/O MAP address. Programming knowledge is not required. You
can easily start up the wireless network without the need for software.
In addition, the wireless network can be extended with up to 98 RS-485 stations
(RAD-RS485-IFS, Order No. 2702184). I/O data can therefore be distributed across vari-
ous media using the thumbwheel.
The PSI-CONF configuration and diagnostic software for special functions and diagnostic
options of the wireless module is available free of charge.
