BUILT-IN ANALOG OUTPUT BLOCK

2.8.1 Built-In Analog Output Block Operation

The Built-In Analog Output block is a data repository for the instrument. One block

services one analog output from the built-in circuit. All values are buffered in one of

five possible task state tables. Process output routines use these tables to pass

data between the built-in analog output blocks, which are updated every 50

milliseconds, and the process algorithm blocks which run at the configured scan

group interval.

The input connected to the AOUT block is scaled and latched according to the

configuration of the block parameters. All valid data is then sent to the output

circuit during each 50 millisecond scan cycle.

Built-in analog output blocks can generate diagnostic errors based upon the

following possible conditions:

• I/O communications error

• Output circuit status error (used to determine when to get output circuit error

code)
