In the Switchsync PWC600 pre-configuration, the OPLOGTRIG output of SSCPOW provides such a
composite trigger signal. TsSrcSel should be set to "Signal Time" to assure correct storing of the
application generated time stamp.
In an application for periodic process monitoring (for example, maximum temperature attained in a
day), where measured data are stored immediately on triggering, a simple binary (Boolean) signal
can be used to trigger OPERLOG. In this case, TsSrcSel should be set to "System Time", to generate
the time stamp from the IED's system time when TRIG_IN was activated. In this case, the CB
operation type (Close or Open) will be stored as "not applicable".
Processing of trigger signals can be further controlled by the TrgModOpn (for open operation) and
TrgModCls (for close operation) parameters. The options are:
• Do not log: A trigger signal for the respective operation (Close or Open) will not store an
operation record.
• Log without values: Operation record will include only the operation type (Close or Open) and
the time stamp.
• Log with values: Operation record will include operation type (Close or Open), time stamp, and
the values at the connected inputs.
Grouping and categorizing operation data
To enable grouped and categorized presentation of logged data in LHMI or WHMI, two settings and
one input are provided. One instance of OPERLOG allows to connect maximum eight real-value
inputs; if more than eight values are to be logged with the same trigger signal, additional function
block instances are required. To logically group these instances together in the database, Type
should be set to the same value.
If, within one Type of OPERLOG, a client such as trend graph page in WHMI is configured to show
the values of selected inputs only, the InputxGroup settings allow this segregation. They should be
set according to the class of monitored process data, for example, "Accuracy" (of controlled switching
operations) or "Ambient" (temperature).
The input signal MODE, which is stored together with the other input data, provides dynamic
categorization (at runtime). It is intended to give a status evaluation of each switching operation at a
glance. This mode information is further explained in Section.
Configuring instances in ACT
Operation log instances can be configured to store phase segregated values such as operation times
of the three circuit breaker poles, or phase independent values such as ambient temperature.
For phase independent signals, configure OPERLOG as individual instance(s). An example of
possible trigger connections is shown in
