Stop program screen.
(a) Program name
Select a program set in the Program tab of the PLC parameter dialog box.
A program name cannot be entered as desired.
(b) Stop mode
1) Executing "After stop, output stop" to the following programs operates as follows.
• Scan execution type program
Outputs are turned off (non-execution) in the next scan.
The program enters the standby status after the next scan (This operation is the same when the POFF
instruction is executed).
• Low-speed execution type program
The low-speed execution type program is suspended and outputs are turned off in the next scan.
The program enters the standby status after the next scan (This operation is the same when the POFF
instruction is executed).
• Stand-by type program
The program stops after outputs are turned off for one scan as a scan execution type program.
Therefore, "Execute count" is also increased by 1.
2) "Execute count" is increased by 1 if an error occurs in the RET or IRET instruction while outputs are turned
off for one scan as a stand-by type program.
In this case, the execution type will be "Scan execution".
Even if "After stop, output stop" is executed, the output may not turn off depending on an instruction.
For details, refer to the section for the POFF instruction in the following.
