On-line command P{constant}={expression}
Program commands I{data}={expression}, M{data}={expression},
Q{data}={expression}.
PAUSE PLC
Function: Pause execution of PLC programs
Type: Motion program (PROG or ROT), PLC program
Syntax: PAUSE PLC {constant}[,{constant}...]
PAU PLC {constant}[,{constant}...]
PAUSE PLC {constant}[..{constant}]
PAU PLC {constant}[..{constant}]
where:
 each {constant} is an integer from 0 to 31 representing the PLC number
This command causes Turbo 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.
If the PLC program is paused from within that PLC, execution is stopped immediately after the PAUSE
PLC command.
If the PLC program is paused while it is not in the middle of a scan, which is always the case if it is
paused from another background PLC, it will obviously be paused at the end of a scan – after an
ENDWHILE or after the last line.
If the PLC program is paused while it has been interrupted in the middle of a scan (for example, from a
motion program), its execution will resume after the interrupt and continue until after it executes any of
the following:
 Any ENABLE PLC, DISABLE PLC, PAUSE PLC, or RESUME PLC command
 An ENDWHILE command
 The last line of the program
Execution will be paused at this point.
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 no buffer is open when this command is sent to Turbo PMAC, it will be executed immediately as an
on-line command.
Examples:
PAUSE PLC 1
PAUSE PLC 4,5
PAUSE PLC 7..20
PAU PLC 3,8,11
PAU PLC 0..31
