Pump Avatars Control Modes

The Pump avatar has three types of control modes, described below. The type of Control mode for the avatar can be selected during the configuration of the avatar.

• Remote Control mode: The operational control is managed by the PLC.

• Autonomous Control mode (available on pump avatar only): The operational control of the avatar in autonomous mode comes from configurable PV Control inputs. PV Control inputs are one or two PV inputs or PV switches. They have the following settings:

  • Analog PV Control inputs: PV control level, PV control logic, and PV control hysteresis.

  • Digital PV Control inputs: PV control logic.

  Degraded mode does not impact the Autonomous Control mode.

• Local Control mode: The operational control is managed by local control inputs (digital I/O). When the avatar is in Local Control mode, the configured PV Control input conditions need to be satisfied.

The operational control of the avatar can transition out of the configured control mode based on the following two conditions:

• The system degraded mode status

• The manual mode override status

Configured Control Mode:

• Remote Control mode: The avatar transitions into Local Control mode if the system enters degraded mode or if the avatar’s Manual Mode Override command is issued. The avatar transitions from Local Control mode back to the configured Remote Control mode when the system is not in degraded mode and the avatar’s Manual Mode Override is not issued.

• Autonomous Control mode: The avatar transitions into Local Control mode if this avatar’s Manual Mode Override command is issued. The system degraded mode status does not impact the Autonomous Control mode. The avatar transitions from Local Control mode back to the configured Autonomous Control mode when the avatar’s Manual Mode Override command is not issued.
