5. The Range Values allow the Loop Current to be converted to a percent for use by the actuator (e.g. to use as the actuator setpoint).
6. Issuing this command will write the current Primary Variable value to the Upper Range Value.
7. Issuing this command will write the current Primary Variable value to the Lower Range Value.
8. The Loop Current may not reflect the process while the Self test is executing. A master must not generate spurious error messages or disconnect form the Field Device
while the Self test is in progress.
9. This is equivalent to cycling the power off and then back on to the Field Device. Communication with the network will be temporarily lost. The device will not respond
to subsequent commands until the reset is complete. In addition the Loop Current may not reflect the process while the Device Reset is executing. A master must not
generate spurious error messages or disconnect from the Field Device while the Device Reset is in progress.
10. This trim is typically performed by adjusting the Loop Current to 4.00 milliamperes and sending the measured value to the Field Device. In response the Field Device trims
its calibration of the Loop Current to match the value received from the Master. Response Code 9 “Incorrect Loop Current Mode or Value” will be returned if the device is
not in the proper mode to allow the Loop Current to be calibrated or if the current is not set to exactly the minimum value.
