High-speed Counter/Pulse Output Instructions Section 3-20
Description INI(880) performs the operation specified in C for the port specified in P. The
possible combinations of operations and ports are shown in the following
table.
■ Starting Comparison (C = 0000 hex)
If C is 0000 hex, INI(880) starts comparison of a high-speed counter’s PV to
the comparison table registered with CTBL(882).
Note A target value comparison table must be registered in advance with
CTBL(882). If INI(880) is executed without registering a table, the Error Flag
will turn ON.
■ Stopping Comparison (C = 0001 hex)
If C is 0001 hex, INI(880) stops comparison of a high-speed counter’s PV to
the comparison table registered with CTBL(882).
