5.3.5 Failure of supply voltage L+ at BaseUnit BU...D
Failure of the supply voltage L+
The I/O modules react as follows to failure of the supply voltage L+ on the BaseUnit BU...D:
● If an I/O module is removed during failure of the supply voltage, a pull interrupt is
generated.
● If an I/O module is installed during failure of the supply voltage, a plug interrupt is
generated.
5.3.6 STOP of the IO controller and recovery of the IO device
STOP of the SIMATIC IO controller
Diagnostics received from the IO device while the IO controller is in STOP do not initiate a
call of any corresponding OBs when the IO controller goes into RUN. Read the E00C
H
data
record in startup OB using the instruction "RDREC". This record contains all diagnostics for
the slots assigned to an IO controller in an IO device.
Recovery of the SIMATIC IO devices
If you want to read the occurring diagnostics in the STOP state of the IO controller, you have
to read the E00C
H
data record with the "RDREC" instruction. This record contains all
diagnostics for the slots assigned to an IO controller in an IO device.
