Start the HSC configuration by choosing a counter type according to the type of sensor you are using and the application need.
In the Counters editor, select a Counting function from the list that offers the following types of counters (for more information, refer to the Counter Function):
oHSC Simple
oHSC Main Single Phase
oHSC Main Dual Phase
oFrequency Meter
oPeriod Meter
The Frequency Meter type and the Period Meter type are both based on an HSC Main type.
For each counter defined in the Counters editor, a default Instance name is assigned by EcoStruxure Machine Expert. This default Instance name is editable. You must use exactly the same instance name as an input to the function blocks dealing with the counter.
This table presents the different types and modes available:
