STOP of the IO controller and recovery of the IO device
STOP of the SIMATIC IO controller
Diagnostics frames 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. You must read
the data record E00C
H
with the "RDREC" instruction in OB 100. 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 diagnostics of a station after its return, you have to read the E00C
H
data record with the "RDREC" instruction in OB 86. This record contains all diagnostics for the
slots assigned to an IO controller in an IO device.
