…QV> of another function block
Actual Value …QV>
The actual value …QV> can be assigned the following operands:
• Markers MD, MW, MB
• Analog output QA01
Displaying the Parameter Set in the PARAMETERS Menu
• + Access enabled
• - Access disabled
Contacts
• CF01OF to CF04OF: Actual value ≥ Upper set point
• CF01FB to CF04FB: Actual value ≤ Lower set point
• CF01ZE to CF04ZE: Actual value = Zero
Coils
CF01EN to CF04EN: enable of the counter with coil status = 1.
Memory Requirement of the Frequency Counter
The frequency counter function block requires 40 bytes of memory plus 4
bytes per constant on the function block inputs.
Retention
The frequency counter does not retain actual values, as the frequency is
re-measured continuously.
