5-7 Counter Area (C)
The Counter Area contains Completion Flags (1 bit each) and counter PVs (16 bits each). A Comple-
tion Flag is turned ON when the counter PV reaches the set value (counting out).
Completion Flags and counter PVs are automatically retained in the built-in non-volatile RAM even if
the power supply is interrupted.
Counter numbers range from C0 to C255.
.
