Voltages > 30 V DC might damage the processor module and the connected
modules.
Make sure that the supply voltage never exceeds 30 V DC.
1.3.1.1.5 State LEDs and operating elements
The processor modules, PM50xx series, have a RUN/STOP button. By pressing the RUN/STOP
button, the processer modules switch between RUN mode and STOP mode. By long-pressing
RUN/STOP button during the processor module power on phase, the processor module will be
in MOD1.
The processor modules PM50xx indicate their states of operation via 5 LEDs located on the
upper left side of the processor module.
