2.3.1
Global start disable for channel
User/PLC
A global Start disable can be set for the selected channel via the HMI or from the PLC.
Function
When Start disable is set, no new program starts are accepted for the selected channel.
Start attempts are counted internally.
If a start is executed by the PLC before a global block disable is sent from the HMI to the
NCK, the program is not stopped by the Start disable and its status is transmitted to the HMI.
NC Start disable and global Start disable have the same effect on the internal counter for
starts that have been sent but not executed. (OPI variable startRejectCount).
Bypassing global Start disable
The interface signal:
DB21, ... DBX7.5 (PLC → NCK)
allows the PLC to temporarily bypass a global Start disable.
0:
Global Start disable is effective
1:
Global Start disable is temporarily canceled.
Messages
If desired, a message can be issued when a Start attempt occurs while a global block
disable is active.
The control is exercised using machine data:
MD11411 $MN_ENABLE_ALARM_MASK Bit 6
1:
Alarm 16956 appears: Channel %1, Program %2 cannot be started because of
"Global Start disable".
0:
Start attempts when a global block disable is set are not signaled by an alarm.
