Channel 2 – Position and Bus Mode

The channel 2 Discrete Input function block, DI_POSITION_AND_BUS_MODE_CHAN, makes actuator

status information available to other function blocks. The status information describes the position of

the actuator, that is open or closed, the direction of motion of the actuator, that is opening or closing,

and the operating mode, that is either Local, Remote, or Stop (off).

Channel 3 – Position Channel

The Channel 3 Discrete Input function block, DI_POSITION_CHAN, makes actuator status informa-

tion available to other function blocks. The status information describes the position or direction of

motion of the actuator, that is either Opened, Closed, Opening, Closing, or Stop.

Channel 3 DI_POSITION_CHAN Value

Opened 0x01

Closed 0x02

Opening 0x04

Closing 0x08

Stop 0x10

Channel 4 – Actuator Faults 1

The Channel 4 Discrete Input function block, DI_ACTUATOR_FAULTS_1_CHAN, makes actuator faults

available to other function blocks. The reported faults include:

• Valve jammed in motion due to a tripped torque switch

• Valve was manually moved with the actuator handwheel

• An over torque condition while traveling

• Loss of electrical phase

• Thermal overload indicating the motor has overheated and the thermistor has opened.
