4.2 PROFIBUS-DPV0
Global control function services
Specify which service is applied to which group through the buffer memory.
■
SYNC service
This service starts SYNC (output synchronization) mode.
During SYNC mode, DP-Slaves refresh the output status every time when receiving a SYNC service.
Without a SYNC service received, DP-Slaves hold the output status.
■
UNSYNC service
This service stops SYNC (output synchronization) mode.
■
FREEZE service
This service starts FREEZE (input synchronization) mode.
During FREEZE mode, DP-Slaves refresh the input status every time when receiving a FREEZE service.
Without a FREEZE service received, DP-Slaves hold the input status.
■
UNFREEZE service
This service stops FREEZE (input synchronization) mode.
(1) Group 1
(2) Group 2
(3) Group 5
(4) Group 8
Send a SYNC service to group 1.
When SYNC service is executed: Output image memory values are output once at the timing of receiving a SYNC service.
When UNSYNC service is executed: Output image memory values are output without change. (Normally in this mode)
(1) Group 1
(2) Group 2
(3) Group 5
(4) Group 8
Send a FREEZE service to group 5.
When FREEZE service is executed: Actual input is input to the input image memory once at the timing of receiving a FREEZE service.
When UNFREEZE service is executed: Actual input is input to the input memory without change. (Normally in this mode)
