4 Functions of the Operator Module
This chapter describes the operation of the PLC via the operator 
module. An example of commissioning operations is used to 
explain the individual functions. 
Initial PLC startup 
When the power supply is switched on, the UPS device closes the 
Power Fail circuit. The PLC operating system is started and the 
”Waiting for Signal” message appears on the display of the oper-
ator module. The STOP, RUN and SF (SF = Central error) LEDs of 
the operator module are not lit. The STOP LED lights up and the SF 
LED light up after a few seconds.
If there is no program in the PLC, and the operating mode selector 
switch (OMS) is set to STOP, the display will show the following 
information after a few seconds:
The STOP and SF LEDs are lit. When the SF LED is lit, this indicates 
that the PLC did not find a bootable program during the startup. 
The ! in the display indicates that the PLC is in STOP status.
