Function
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 reg-
istered with CTBL(882).
Note A target value comparison table must be registered in advance with CTBL(882). If INI(880) is executed with-
out 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 regis-
tered with CTBL(882).
C INI(880) function
0000 hex Starts comparison.
0001 hex Stops comparison.
0002 hex Changes the PV.
0003 hex Stops pulse output.
If C is 0002 hex (i.e., when changing a PV),
NV and NV+1 contain the new PV. Any val-
ues in NV and NV+1 are ignored when C is
not 0002 hex.

Error Flag P_ER ON if the specified range for P, C, or NV is exceeded.
ON if the combination of P and C is not allowed.
ON if a comparison table has not been registered but starting comparison is specified.
ON if a new PV is specified for a port that is currently outputting pulses.
ON if changing the PV of a high-speed counter is specified for a port that is not specified for a high-speed counter.
ON if INI(880) is executed in an interrupt task for a high-speed counter and an interrupt occurs when CTBL(882) is
executed.
OFF in all other cases.
