Circuit Configuration
• When the output current of any output exceeds the detection current, the output for
that point will turn OFF. At the same time, the ERR indicator will light and the corre-
sponding flag (one for each common) in the Basic I/O Unit Information Area (A050 to
A069) will turn ON.
