DISCRETE INPUT BLOCK

The DI takes the manufacturer’s discrete input data, selected by channel number, and makes it available to other function blocks as its output. The output will have a value of either true or false along with the status of the output. A custom feature of the DI block in the 848L is the ability to pack 8 status bits into the single output of a DI block. This is accomplished by selecting the appropriate channel number for packed data. This feature is used in custom applications implemented in control systems such as DeltaV.

The DI block supports a function to invert the input and alarming.
