6.9 DVC70
The DVC70 memory module is capable of storing (logging) data, date
and time information to nonvolatile memory in the DVC70. The
information to be stored is transmitted from the DVC7/10 via the
Controller Area Network (CAN bus) to the DVC70. The information on
the DVC70 can be downloaded to a laptop or PC using a RS232
communication port for analysis or review.
The DVC70 is capable of storing 3 types of logs:
Trend logs – consist of up to 10 monitored variables. Data storage is
automatic and independent of time or data value.
Event – consist of up to 5 monitored variables. This data logging
operation is started and stopped by the user’s application code.
Fault logs – consist of up to 5 monitored variables. This data logging
operation is started and stopped by the user’s application code.
