Stop Pulse Output
If C is 003, INI(61) stops pulse output. Refer to
1-5 Pulse Output Function
for
details on stopping Pulse I/O Board pulse outputs 1 and 2.
Note
Pulse output can be stopped only when pulses are not currently being output.
The Pulse Output Flag (AR 0515 or AR 0615) can be used to check pulse out-
put status.
Flags

P1+1 exceeds the data area boundary. (C=002)
There is an error in the operand settings.
INI(61) is executed in an interrupt subroutine while a pulse I/O or
high-speed counter instruction is being executed in the main program.
5-16-9 HIGH-SPEED COUNTER PV READ – PRV(62)
Limitations
ID and D+1 must be in the same data area.
DM 6143 to DM 6655 cannot be used for D.
Description
PRV(62) can be used with the functions listed in the following table.
When the execution condition is OFF, PRV(62) is not executed. When the exe-
cution condition is ON, PRV(62) reads data specified by P and C and writes it
to D or D and D+1.
The port specifier (P) specifies the high-speed counter or pulse output that
will be controlled.
