For your information, the PXM20 operator unit displays a list of all
inputs and outputs of the tested automation and control stations,
grouped according to signal type (analog, binary or multi-state, see
Figure 11-4).

can be configured. During the wiring test (=No application loaded) it
is always assumed that the analog input signal is a type LG Ni100
signal.
Navigate to the top level (the openinig menu of the wiring test) by
repeatedly pressing ESC, otherwise you will have to perform a
master reset of the PX automation station before you can carry out a
new wiring test.
The PXM20-E operator unit must be able to communicate with the
automation station via IP, and must not be configured for DHCP.
The Foreign Device option must be disabled (this is also the default
value). It is recommended that you operate the automation station to
be tested and the PXM20-E operator unit in the same range as the
default IP addresses and subnet masks. During the wiring test, the
PXM20-E operator unit assigns the automation station a temporary
IP address which is one digit higher than its own IP address:
Example: IP address of PXM20-E: 172.16.87.14
 IP address of automation station: 172.16.87.15.
The use of this IP address is not checked.
If the wiring test is carried out on a different PXM20-E operator unit,
a master reset of the automation is required before you start.
