Temperature
Temperature (TEMPERATURE [48]) displays the
internal temperature of the instrument in either
degrees Fahrenheit or Celsius.

Cycle Counter
Cycle Counter (CYCLE_COUNT [73]) records the
number of times the travel changes direction. The
change in direction must occur after the deadband has
been exceeded before it can be counted as a cycle.
Travel Accumulator
Field Communicator TB

Travel Accumulator
Travel Accumulator (TRAVEL_ACCUM [72]) indicates
the total change in travel, in percent of ranged travel.
The accumulator only increments when travel exceeds
the deadband. Then the greatest amount of change in
one direction from the original reference point (after
the deadband has been exceeded) will be added to
the Travel Accumulator.
Travel Count

Travel Count
Travel Count (TVL_COUNT [43.1]) is the Travel
Sensor readback displayed in A/D counts.
