11.2 Internal and External Power Supply
The slot PLC can be supplied by 5 V or 3.3 V (via PCI) or by an additional
power supply externally with 24 V. The permitted voltage range for external
powering is 18 … 30 V.
11.3 Reset Behaviour
The slot PLC has no reset connection via the PCI bus to the PC reset
signal. This means that a reset of the PC for example when using the front
panel reset button of the computer does not influence the slot PLC
behaviour.
The PowerOn-Reset will be served from both power sources (internal und
external).
11.4 RUN/STOP Switch
The PLC program’s operating condition in the slot PLC can be changed
using the physical switch at the front of the slot PLC and may get the status
•
RUN
respectively
•
STOP
In case the CoDeSys programming interface is logged in, you can change
the operating condition within CoDeSys without using the physical switch.
Please pay attention: This may result in a condition where CoDeSys
programming interface switches the PLC into mode STOP while the
physical switch is still in position RUN and during the next boot up cycle the
PLC will go the automatically into RUN mode unintended. Please move the
switch into position STOP to prevent an unintended restart.
