Basic Function Blocks

In This Chapter

Purpose of this Chapter

This chapter deals with the basic usage of function blocks within transmitters
and the minimum configuration needed to make these transmitters active.

Basic Function Blocks

Basic function blocks are needed to make a transmitter functional and readable
within RSFieldbus. These blocks are the Resource Block (RES), Transducer
Block (XDCR), Analog Input Block (AI), Analog Output Block (AO), Digital
Input Block (DI), and Digital Output Block (DO).

Not all transmitters have these function blocks, but the majority of them do.

Resource Block

The Resource Block is the base block needed in all transmitters before the
transmitter can become active. It holds data specific to the transmitter.

The important parameter within the RES is the MODE_BLK. Putting this
parameter to AUTO allows the function block to be active upon download.
