MCTB
140
If more than one MCTB
utilizes the same entries, the data from all units with the same ID’s will be combined
under the one ID in the database. This will render the data unusable as there will be no way to split the data
between the different units and know which data points are from each unit. If this does occur; however, the
MCTB will still have a local copy of the data stored to the local data log file(s). This provides a backup copy of
the data just in case the ID numbers of more than one unit are identical.
The
Length (days) field sets the length of a data file in number of days. It can be set for 1 to 31 days. Once
the selected number of days has elapsed, a new data file will be created and logging will continue in the new
file.
The
Interval (secs) field is used to set the rate at which points are written to the log file which equates to the
sample rate in seconds. When the
“Fixed Interval” option is turned on, the logging interval will be automatically
set to record at minute intervals based on the number of days set for the file. If the file is set for 1 day in length,
the logging rate will be at 1-minute intervals. If the file is set for 7 days, then the logging rate will be every 7
minutes. This keeps the data file size manageable and able to be viewed by the MCTB data viewer.
The log interval can be manually set to any rate between 1 and 1860 seconds in any combination with the
number of days before a new file is started. To do this, turn off the
“Fixed Interval” option and enter in the
desired logging rate in seconds.
NOTE: Logging at shorter intervals allows the MCTB to capture fast changing processes, but the data files can
become extremely large. Files that exceed the capability of the MCTB data viewer (>520KB in size)
will have to be extracted from the MCTB using a USB memory stick or FTP file transfer in order to be
viewed remotely on a PC.
Files larger than the 520KB limit will not be automatically, digitally signed by the MCTB. If the files are
to be digitally signed, this must be done manually by extracting the files and using the FDC data viewer
program running on a remote PC.
To manually start data logging, press the
“Data” button. Any time logging is enabled, the indicator on the Data
button will be illuminated. To stop data logging, press the Data button again. Data logging can also be started
automatically by turning on
the “Start” or “Program” option.
The
Start option automatically turns data logging on whenever the MCTB is first powered on. This action
simulates that of a standard chart recorder.
The
Program option is a convenient method for gathering information that pertains only to the operation of an
automatic ramp/soak program. When selected, the MCTB will turn the data logger on at the beginning of a
program and off once the program is completed. This eliminates the need to scan through extensive data
records to find the specific information you are looking for from a particular time period.
NOTE: The MCTB will automatically use the program name as the filename for the log file (up to 14
characters). This provides a simple identifier for log files that pertain only to automatic program
operation. Any entry made in the File Name field will be ignored.
The
Email icon next to the data log on/off button allows the user to select the currently open data file and email
the file to any user that has been setup to receive emails from the MCTB.
The
Disk icon next to the Email icon allows the user to save the currently opened data file to a USB memory
device connected to the MCTB.
