1.2.2. Advanced Diagnostics
1.2.2.1. Error Log
Error Log feature provides information related to relative time stamp of errors/faults
detected by device. The device can store last 10 errors occurred when error log feature
is enabled. There is also provision to reset error log to capture the new errors. We can
read the error log information and the elapsed time since the error occurred from host
application.
1.2.2.2. Configuration Change History
The feature provides history for parameters configuration change.
For example, if Differential Pressure damping is modified from 2.0 to 3.0 then using
configuration history user can find that previous value of DP damping is 2.0.
Device can hold history for last 5 configured parameters data.
1.2.3. Physical Characteristics
As shown in Figure 1-1 , the SMV800 is packaged in two major assemblies: the Electronics
Housing and the Meter Body. The elements in the Electronic Housing respond to setup
commands and execute the software and protocol for the different pressure measurement
types.
Figure 1-1 shows the assemblies in the Electronics Housing with available options.
The Meter Body provides connection to a process system. Several physical interface
configurations are available, as determined by the mounting and mechanical connections,
all of which are described in the SMV Transmitter Users Manual, see
