DATA LOGGER MODE
— This setting configures the mode in which the data logger operates. When set to “Continuous,” the
data logger actively records any configured channels at the rate as defined by the
DATA LOGGER RATE
. The data logger is
idle in this mode when no channels are configured. When set to “Trigger,” the data logger records any configured channels
at the instance of the rising edge of the
DATA LOGGER TRIGGER
source FlexLogic operand. The data logger ignores all
subsequent triggers and continues to record data until the active record is full. Once the data logger is full, a CLEAR DATA
LOGGER command is required to clear the data logger record before a new record can be started. Performing the CLEAR
DATA LOGGER command also stops the current record and resets the data logger to be ready for the next trigger.
DATA LOGGER TRIGGER
— This setting selects the signal used to trigger the start of a new data logger record. Any FlexLogic
operand can be used as the trigger source. This setting only applies when the mode is set to “Trigger.”
DATA LOGGER RATE
— This setting selects the time interval at which the actual value data is recorded.
DATA LOGGER CHNL 1(16)
— This setting selects the metering actual value that is to be recorded in Channel 1(16) of the data
log. The parameters available in a given relay are dependent on: the type of relay, the type and number of CT/VT hardware
modules installed, and the type and number of Analog Input hardware modules installed. Upon startup, the relay
automatically prepares the parameter list. A list of all possible analog metering actual value parameters is shown in
Appendix A: FlexAnalog Parameters. The parameter index number shown in any of the tables is used to expedite the
selection of the parameter on the relay display. It can be time-consuming to scan through the list of parameters via the
relay keypad/display—entering this number via the relay keypad causes the corresponding parameter to display.
DATA LOGGER CONFIG
— This display presents the total amount of time that the Data Logger can record the channels not
selected to “Off” without overwriting old data.
