Coordination Via Part Program And Synchronized Action (Lock, Unlock, Cancel) - Siemens SINUMERIK 840D sl Function Manual

Detailed description

3.10 Coordination via part program and synchronized action (LOCK, UNLOCK, CANCEL)

Application
The synchronized actions defined by the machine manufacturer to react to certain machine
states should not be changed after commissioning.
Note
It is recommended that the protection of synchronized actions should not be activated during
the commissioning phase as otherwise a Power on reset is required at each change to the
synchronized action.
Example
In a system with two channels, the synchronized actions of the following identification number
areas should be protected:
Channel 1: 20 ... 30
Channel 2: 25 ... 35
Machine data configuration
NC-global protection area:
● MD11500 $MN_PREVENT_SYNACT_LOCK[0] = 25
● MD11500 $MN_PREVENT_SYNACT_LOCK[1] = 35
Channel-specific protection area for channel 1:
● MD21240 $MC_PREVENT_SYNACT_LOCK_CHAN[0] = 20
● MD21240 $MC_PREVENT_SYNACT_LOCK_CHAN1] = 30
Channel-specific protection area for channel 2:
● MD21241 $MC_PREVENT_SYNACT_LOCK_CHAN[0] = -1
● MD21241 $MC_PREVENT_SYNACT_LOCK_CHAN[1] = -1
A separate protection was not defined in channel 2 and therefore the NC-global protection
area applies.
3.10 Coordination via part program and synchronized action (LOCK,
UNLOCK, CANCEL)
Each modal and static synchronized action must be assigned a unique identification number
during the definition:
Program code
