To synchronize High Frequency data points and Low Frequency data points to each other, two additional data points must be subscribed, "CYCLE" of the "High frequency data" type and "SYNC_CYCLE_HF" of the "Low frequency data" type.
Once you have done this, the SINUMERIK Connector will always provide the current CYCLE value for all low frequency as well as for the high frequency data points. This means that now the low frequency data values can be synced to the corresponding high frequency data values.
Note:
If you want to combine high frequency data values and low frequency data values, always use the CYCLE and SYNC_CYCLE_HF value. Do not rely on any timestamps, as they can differ from each other due to various technical reasons.
