Operation counter
4.9.4
The TPOS01 function has an operation-counter†; the user can utilize the operation counter to
predict the lifespan of an EDS. The user can select a count mode in response to a device signal.
Table 4.9-22 and Figure 4.9-45 show the mode, for which a user is required to change a mode
in response to a device signal and the signal of the device such as the EDS. For instance of the
P1-control in the TPOS01 function, a user can select the mode using scheme switch [TPOS01-
P1CNTS], which is set to C-On; counting-up is performed when a switch-gear signal gives rise
to a change in state from "Open to Closing".
Mode Description
Counting-up is performed when a signal changes to closed (ON). When the signal
C-On
is changed from "Open to Closed", the counter value is incremented.
Counting-up is performed when a signal changes to open (OFF). When the signal
C-Off
is changed from "Closed to Open", the counter value is incremented.
Counting-up is made when any state change occurs: "Open to Closed" and
C-OnOff
"Closed to Open".
Stop the count function
NA
†Note: The operation-counter value is not cleared when power is removed from the IED.
This counter is available in the TPOS01 to TPOS03 functions.
The user can change the value of the operation-counter from either the front panel or
remotely. For example, in the sub-menu for "Operation counter", the user can set a user-
preferred value for the operation-counter. See Chapter
on how to operate the sub-menu.

Note: With regard to the signal "TPOS01_ST_P1", the sub-menu represents it as
"TPOS_Dev1-P1". Analogous to the signal "TPOS01_ST_P1", the signals
"TPOS01_ST_P2" and "TPOS01_ST_P3" are represented as "TPOS_Dev1-P2" and
