The PLC program’s operating condition in the S7-PCI315 PLC can be changed using the physical switch at the front of the PLC and may get the status:

  • RUN
  • STOP

In case the S7 for Windows® or STEP®7 programming unit is logged in, the PLC state can be altered, without using the physical switch.

Please pay attention: This may result in a condition where the programming unit 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.
