17.2.5 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 F
OUNDATION™ 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.
Refer to page 162 for the list of parameters.
