Description
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.
ER: The specified port and function are not compatible.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
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.

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.
