250
Manual 11/10 MN05002001Z-EN www.eaton.com
5.9.2 Wiring of the function block
You wire the function block in the circuit diagram with its coils and its
contacts.
5.9.2.1 Coils
The coils of the function block is used in the circuit diagram.
5.9.2.2 Contacts
The contacts of the function block are evaluated in the circuit diagram. A
closed contact indicates:
5.9.2.3 Example of a high-speed incremental counter:
Figure 152: Wiring the function block coils
The count inputs of function block CI01 are already permanently assigned to
device inputs I1 and I2. The coils of the function block are connected directly
here to the device inputs.
￫
Note that the digital inputs I1 to I4 are permanently assigned to
the incremental counter function blocks provided:
• I1: Counter input for counter CI01, channel A.
• I2: Counter input for counter CI01, channel B.
• I3: Counter input for counter CI02, channel A.
• I4: Counter input for counter CI02, channel B.
