Note
If you use the TIA Portal for configuring, it automatically checks the configuration for
consistency and informs you as of which module you must open up a new power segment.
Overload in the power segment
If an overload occurs in the power segment, the red SF LED on the system power supply
(PS) flashes. All I/O modules to the right of the PS in the power segment will be switched off.
Remedy:
1.
Correct the configuration in the power segment of the overloaded PS.
2.
Switch the supply voltage power off and on again via the on-off switch on the PS.
3.
Switch the CPU from STOP to RUN mode.
Reference
Information about the required power is available in the section Power balance calculation
(Page 104).
Additional information on the performance values (power feed, power consumption) of the
CPU, interface module, system power supply, and I/O modules can be found in the manuals
