Counter function for the general (GCNT)
When a signal is generated externally and the signal is received by generic counter function
(GCNT), the GCNT function can count their signal transitions. Figure 3.7-1 shows signals are
generated repeatedly. For example, if the number of generated signals should be reported, the
GCNT function counts the number of the signal transitions; the function can report them. A
binary input-circuit (BI) is used to receive the signal, when a device (external object) reports
its state.

Note: The implementation of particular features is dependent upon the selection of
hardware and the configuration of functions. Several IED models do not support certain
features. To determine whether a particular feature has been implemented within an IED,
identify the IED ordering number; and check the order number for the “G&T position” whilst
referring to the comparison table below. For more information, see Appendix: Ordering .
