– If the tracking cable was removed, connect
the tracking cable to the connectors of the
CPU modules of the two systems.
– When the error is not resolved after connect-

CONTROL EXE.
The standby system has been switched to the
control system in a redundant system. (Detected
by the CPU that was switched from the standby
system to the control system). Since this error
code does not indicate the error information of
the CPU module but indicates its status, the
error code and error information are not stored
into SD0 to SD26, but are stored into the error
log every system switching. (Check the error
information by reading the error log using GX
(IEC) Developer.)
