5.3 SYNC/FREEZE groups
Assigning the SYNC/FREEZE group to the DP slave
A DP master with the corresponding functionality can send the control commands SYNC
and/or FREEZE for synchronization of the DP slaves simultaneously to a group of DP
slaves. You must assign SYNC/FREEZE groups to the DP slaves for this purpose.
Requirement: A DP master system has been created in the project.
Procedure
To assign a DP slave to a SYNC/FREEZE group, follow these steps:
1.
Select the DP interface of the DP slave you want to assign to a group in the device view
or network view.
2. Select the check boxes for the required SYNC/FREEZE groups under the group
"SYNC/FREEZE" in the Inspector window.
You can assign each DP slave to only one SYNC/FREEZE group.
