Symbol Description
The start of program "n" for process control
(SSTP n)
Start the specified process "n" and clear the pro-
(NSTL n)
cess currently operated. (Scan execution type)
Start the specified process "n" and clear the pro-
(NSTP n)
cess currently operated. (Pulse execution type)
Resets the currently operated process "n".
(CSTP n)
End of step ladder area
(STPE )
Resets the currently operated processes "n1" to
SCLR n1, n2
"n2".
Executes the specified subroutine. When return-
ing to the main program, outputs in the subrou-
(CALL n)
tine program are maintained.
Indicates the start of the subroutine program "n". 1
(SUB n)
Ends the subroutine program.
(RET )
Indicates the start of the interrupt program "n".
(INT n)
Ends the interrupt program.
(IRET )
Select interrupt enable/disable or clear in "S1"
(DF) ICTL S1, S2 and "S2" and execute.
Change the communication conditions for the
COM port or tool port based on the contents spe-
cified by the character constant.
Change the password specified by the PLC
based on the contents specified by the character
constant.
Set the interrupt input based on the contents
specified by the character constant.
(DF)
SYS1, M
Set the system setting time when a PLC link is
used, based on the contents specified by the
character constant.
Change the communication conditions of the
COM. port or tool port for RS485 based on the
contents specified by the character constant.
Change the setting value of the system register
for the PLC link function.
