Discrete Input Function Block Di1 - Samson FOUNDATION 3730-5 Mounting And Operating Instructions

Parameter description

13.5.5 Discrete Input Function Block DI1

The Type 3730-5 Positioner is fitted with a standard contact input to process binary voltage
signals.
The Discrete Input DI1 Function Block is used for processing the contact input (terminals 87
und 88) and to integrate a FOUNDATION Fieldbus application.
The connected hardware is assigned to the function block by CHANNEL = 1. The OUT_D
parameter is used to link the state of the contact to other function blocks.
Alternatively, an integrated solenoid valve MGV, a discrete valve position with three states
POS_D as well as the Condensed State (NAMUR Status) can be processed.
The binary signal to be linked can be selected over the SELECT_BINARY_INPUT_1 parameter
in the Resource Block.
