4.3.4 Mimic Mode
When Mimic Mode is enabled, the ViewSmart 1600+ will duplicate the data and alarms of another
ViewSmart 1600+ which can be connected by either RS-485 Modbus® or Modbus® TCP/IP. Entering the
communications port and slave ID allows the ViewSmart 1600+ to automatically retrieve programmed
configuration parameters from the Main controller. The Mimic controller's communication port must be
configured as the Modbus® Master and the Main controller's communication port is set to Modbus® Slave.
Once connected, the Mimic controller will update automatically one minute after any parameter is
changed in the Main controller. Alarm Reset from either controller will acknowledge any relay with
Acknowledge set to Yes

4.3.5 SD Card
A 4 gigabyte SD card comes standard with each ViewSmart 1600+. This SD card is not needed for normal
operation, but is useful for data logging and backing up configuration settings.
When the data logger is enabled, every ten minutes the Min, Max, Average, Alarm 1/2/3 status, Fault
status, Calibration status, and Alarm Reset for each active channel is written to the SD card in one minute
intervals. The log files are stored on the SD card by date. Each day a new file is created and stored in a
directory structure as follows: UNIT_NAME\YEAR\MONTH\DAY.csv. The files are comma delimited text
files and work with MS Excel, which can be used to create historical plots of the data.
The first line in the file contains a date stamp. The next line is the header. The header shows the name of
each column. The AVG fields in the header list the zero and span values for that channel. The zero and
span can be used when creating plots. Another line exists for each minute of the day. Those lines are time
stamped with the hour and minute.
The numeric format of the MIN, MAX, and AVG values are based on channel settings. The decimal
precision is the same that is viewed from the unit. This can be adjusted with the decimal points parameter
in each channel's Configure menu.
