5.1.4 Description of the information given by the Data Logger system
5.1.4.1 Combination of devices for reading/setting data from the Data Logger system
By connecting to the separate release bus, parameters, triggers or Data Logger commands can be set, or types and sequences of stored data
can be read.
Device combinations and consequent software combinations allowing this function are as follows:
LSIG-MM + Dialog unit
5.1.4.2 Access to saved data from the system
When the event associated to a trigger takes place or a stopping command is given, the following data will be stored in the recorder:
• Data Logger Trigger, which indicates the type of trigger that has prompted stoppage of Data Logger;
• Time-stamp of the trigger event (day/hour + minutes/seconds/milliseconds) (4 words);
• Data Logger max file, indicating which is the max length file with consistent data;
• Data Logger max address, indicating which is the max stop address with consistent data.
The following information is recorded in the data block for each sampling period:
1. current sample L1
2. current sample L2
3. current sample L3
4. current sample Ne
5. digital input/output (from 16 available. E.g.: inputs/outputs)
6. alarms1 (from 16 available. E.g.: L timing, G alarm, Prealarm)
7. alarms2 (from 16 available.)
8. trips (from 16 available. E.g.: trip of L, S, I, G ...)
5.1.4.3 Information from the system on configuration and status of Data Logger
The following information is provided on the status of Data Logger:
STATUS
Waiting trigger: this means that the Data Logger is enabled and waiting for the event selected as trigger to occur
Data Logger triggered: this indicates that the trigger event has occurred and the Data Logger is recording
Data Logger stopped: this means that recording has been terminated either because it has been completed or because a Data
Logger stop command has been received
CONFIGURATION
Data Logger Config: indicates whether or not the Data Logger is enabled
Data Logger Trigger Type: indicates setting of trigger
Data Logger Stopping delay: indicates Stopping Delay
Maximum recording duration is defined by the sampling frequency set as described in the table in par. 5.1.2.2; recording duration may be lower
than maximum duration allowed if the sum of stopping delay and time elapsed between a restart trigger and a trigger is lower to maximum value,
as given in the following figure:
If the parameters relating to the Data Logger are changed while it is operating, the recording underway is terminated and a new
recording begins on the basis of the new parameters (following a restart trigger command).
