Pressure Analog Input Block
This block takes the input data from the Process Data Transducer Block, selected by the “Totalizer Average Channel” and makes it available to other
function blocks at its output.
L_TYPE parameter
This parameter determines how the values passed by the Process Transducer Block will be used in the block. There are two options; direct or
indirect.
Direct The Process Data Transducer Pressure value is passed directly to the PV of this AI block, and the XD_SCALE information is not used.
Indirect The Process Data Transducer Pressure value is converted to the OUT_SCALE and the information of XD_SCALE is applied.
CHANNEL parameter
This parameter selects the process variable to be used. The CHANNEL parameter, in the ST100 for the Totalizer Analog Input Block MUST be
set to “Pressure Average”.
