Detailed description
2.6 Control and protection of synchronized actions
Note
Protection for synchronized actions must be cancelled while protected static synchronized
actions are being defined, otherwise POWER ON will have to be executed for every
alteration to allow redefinition of the logic.
The effectiveness of the disable is identical, regardless of whether it is specified as:
• global disabling or
• channel-specific disabling.
Example
In a system with 2 channels, synchronized actions should be protected as follows:
IDs 20 to 30 should be protected in the first channel and IDs 25 to 35 in the second. A
combination of global and channel-specific specifications can be used.
MD11500 $MN_PREVENT_SYNACT_LOCK[0] = 25
MD11500 $MN_PREVENT_SYNACT_LOCK[1] = 35
CHANDATA(1)
MD21240 $MC_PREVENT_SYNACT_LOCK_CHAN[0] = 20
MD21240 $MC_PREVENT_SYNACT_LOCK_CHAN1] = 30
CHANDATA(2)
MD21240 $MC_PREVENT_SYNACT_LOCK_CHAN[0] = -1
MD21240 $MC_PREVENT_SYNACT_LOCK_CHAN[1] = -1
