4.10.5.8 Data Logging
Data is recorded internally into non volatile memory. The data log is transferred in the
Comtrade format. The Comtrade format consist of two files, the configuration file (*.cfg)
and the data file (*.dat).
Data logging will continue indefinitely as long as the data interval is set to a non-zero
value. A zero value for the data interval will effectively disable data logging. The data log,
can be downloaded using MODBUS® (see TCC300 protocol document) or DNP (using
file transfer) protocol. The data can be viewed using any Comtrade compatible viewer.
TCC600 provides such a tool.
Data logging interval ranges from 0 to 120 min with an increment of 1 minute. Once data
logging is enabled, the control will store the data in records at the data interval rate. Each
record has the following data:
• Load Voltage
• Primary VA
• Power Factor
• Source Voltage
• Compensated Voltage
• Primary VAr
• Frequency
• Primary Watts
• Load Current
• Tap Position
• Primary Current
• Operations Count
• Circulating/DVAr Current
• Meter Out Voltage
• RTN Counter
The checksum is used to ensure the integrity of the record stored. The average value is
calculated over the data logging interval.
Due to the internal structure of the Comtrade format, time stamping is always performed.
A total of 6 Mbytes (100,000 records) of data can be saved in non volatile memory.
When connected to a TCC300 Tapchanger Control the Data Logging feature provides the
user with the ability to initiate data logging of all control parameters to the selected control
for downloading at a later time.
This feature allows the user to configure the parameters that the control will use to log
data, and to download the logged data to a Comtrade (*.cfg) file. This file format can be
viewed by a third party Common Format for Transient Data Exchange (COMTRADE)
format viewer software.
