The Remote Configuration Mode is used to ensure the unit is not moving during a change of configuration, as this can
be dangerous. If a move command is received while in Remote Configuration Mode, the unit will complete the last write
and exit Remote Configuration Mode and take the move action. The unit must first be placed in “remote configuration
mode” and remain in this mode while these write configuration commands occur to ensure proper operation of the unit.
It is intended that the “write” Device-Specific commands which write unit configuration be used only during commis-
sioning of the unit, and not during normal process control.
If the unit is in “remote configuration mode” and any of the following occur, it will exit the “remote configuration mode”
upon completion of writing the configuration to EEPROM:
• Control knob is moved from REMOTE to LOCAL or STOP
• Network or discrete/local ESD become active
• A discrete open, close or stop command is received by the unit
• A network open, close or stop command is received by the unit
While the unit is in “remote configuration mode”, it will ignore the “position setpoint” value of the HART board and not
move the actuator, until the “remote configuration mode” is exited.
