[Function] Pause the program from the one specified in operand 1 through the other specified
in operand 2, at the current step. Specification in operand 1 only is allowed.
(Note 1) Pausing a program will also pause the operation the program has been executing.
(Note 2) Not only the operation but also the execution of the step itself will be paused.
[Example 1] SSPG 10 12 Pause program No. 10, 11 and 12 at the current step.
Error-generation/output-operation conditions
When one SSPG program is specified (only operand 1 is specified)
No program number error *1
Program already registered
Status of
the specified
program
Program running Program not running
Program not yet
registered
Program number
error *1
Error None None
C03
“Non-registered
program
specification error”
C2C
“Program number
error”
Output operation ON OFF OFF OFF
* The errors shown in the table represent those that generate in accordance with the status of the specified program.
Errors caused by other factors are excluded.
* 1… Program number error indicates specification of a number smaller than 1 or exceeding 64.
When multiple SSPG programs are specified (both operands 1 and 2 are specified)
No program number error *2
Registered program exists inside the specified range *3 Status of
the specified
program
Running program
exists inside the
specified range *4
None of programs
inside the specified
range are running
None of programs
inside the specified
range are
registered
Program number
error *1
Error None None
C03
“Non-registered
program
specification error”
C2C
“Program number
error”
Output operation ON OFF OFF OFF
* The errors shown in the table represent those that generate in accordance with the status of the specified program.
Errors caused by other factors are excluded.
* 2… Program number error indicates specification of a number smaller than 1 or exceeding 64.
* 3… In this case, non-registered programs inside the specified range are not treated as a target of operation with
EXPG, ABPG, SSPG and PSPG commands. This will not affect error generation or output operation.
* 4… In this case, programs not running (but already registered) inside the specified range are not treated as a target of
operation with SSPG and RSPG commands. This will not affect error generation or output operation.
