Error Location
When there is a setting error in the
PLC Setup, the location of that error
is written to A406 in 4-digit hexadeci-
mal.
The CPU Unit will continue operating
and the ERR/ALM indicator on the
front of the CPU Unit will flash.
(A406 will be cleared when the
cause of the error is eliminated.)
