This function block reports feedback from the valve about whether the Port A or Port B side of the valve is
open, which serves as a direction indicator.
Inputs
Inputs to the function block are described.
Item Type Range Description
Pin_A BOOL —— Digital input from the valve actuator to indicate if the valve is in Dir_A position.
Pin_B
BOOL
——
Outputs
The output of the function block is described.
Item Type Description
Dir S8 -1—Valve is in A direction.
0—Valve in in Neutral.
1—Valve is in B direction.
127—Error
Digital input from the valve actuator to indicate if the valve is in Dir_B position.
MC Controller Configurations
Configure inputs and outputs on your controller so they are compatible with the signals of your function
block.
