PAUSE PLC {constant}[..{constant}]

PAU PLC {constant}[..{constant}]

where:

• {constant} is an integer from 0 to 31, representing the program number

Remarks

This command causes PMAC to stop execution of the specified uncompiled PLC program or

programs, with the capability to restart execution at this point (not necessarily at the top) with

a RESUME PLC command. Execution can also be restarted at the top of the program with the

ENABLE PLC command.

The on-line PAUSE PLC command can only suspend execution of a PLC program either at

the end of a scan, which is the end of the program, or at an ENDWHILE statement in the

program.

PLC programs are specified by number, and may be specified in a command singularly, in a

list (separated by commas), or in a range of consecutively numbered programs.

If a motion or PLC program buffer is open when this command is sent to PMAC, the

command will be entered into that buffer for later execution.

Example

PAUSE PLC 1

PAU PLC 5

PAU PLC 3,4,7

PAUSE PLC 0..31
