The synchronization function is used to set/reset the counter operation.
This function is used to synchronize the counter depending on the status and the configuration of the optional SYNC physical input and the function block inputs F_Sync and EN_Sync.
This diagram illustrates the synchronization conditions:
EN_Sync input of the HSC function block
F_Sync input of the HSC function block
SYNC physical input SYNC
The function block output Sync_Flag is set to 1 when the Sync condition is reached.
The Sync condition operates on a rising edge.
Sync condition for a Simple type corresponds to the function block inputs Sync.
The synchronization function can be used in the following counting modes:
oOne shot counter: to preset and start the counter
oModulo loop counter: to reset and start the counter
The SYNC input can be enabled in the configuration.
The synchronization function can be used in the following counting modes:
oOne shot counter: to preset and start the counter
oModulo loop counter: to reset and start the counter
oFree large counter: to preset and start the counter
oEvent counting: to restart the internal timer relative to the time base
oFrequency meter: to restart the internal timer relative to the time base
NOTE: In the Frequency meter mode, the synchronization function can only be activated with the function block pin F_Sync.
