Compatibility
As of SW 4
As of SW 4.1 and later, it is possible to set the channel-specific signal
CHANNEL_NOREADY in the VDI interface in response to alarms.
Up to SW 3.x
MD11412 $MN_ALARM_REACTION_CHAN_NOREADY
controls whether the function channel-specific signal CHANNEL_NOREADY is used. This
ensures that earlier PLC versions remain compatible.
Default setting: CHANNEL_NOREADY signal is not used.
Alarms that have specified a channel-specific NOREADY signal are reconfigured to the
modegroupspecific NOREADY signal.
Clearing criterion
For each alarm, you must specify how the alarm can be cleared again. The following clearing
criteria are possible:
• POWERONCLEAR
The alarm is cleared by switching the control off and then on again.
• RESETCLEAR
When the Reset key is pressed, the alarm is cleared in the channel in which it occurred.
• CANCELCLEAR
The alarm is cleared in any channel when the Cancel key is pressed. The alarm can also
be cleared by means of an NC start or Reset.
• NCSTARTCLEAR
The alarm is cleared in the channel in which the alarm occurred by starting a program.
The alarm can also be cleared by means of a Reset.
• CLEARHIMSELF
The alarm is not cleared by an operator input or action, but explicitly by a "clearAlarm"
programmed in the NCK source code.
• BAGRESETCLEAR
The alarm is cleared by a "BAGRESETCLEAR" command or by executing a Reset in
every channel of this mode group.
• NCKRESETCLEAR
The alarm is cleared by an "NCKRESETCLEAR" command or by executing a Reset in
every channel.
