AO Block Options

This dialog box (Figure 79) consists of both A/O I/O Options and A/O Status Options. IO

OPTS and STATUS OPTS are parameters that control options about the Analog Output

Block (AO)'s signal processing and mode transitions.

Using AO Status Options sends the quality of the status of BKCAL OUT to Bad and its

sub-status is set to sensor failure. The BKCAL OUT value is not affected. The Analog

Output Block (AO) does not alarm (but enables an upstream block to alarm). When this

option is not selected, then the quality of BKCAL OUT is set to Bad and its sub-status is

set to non specific. A block alarm is generated by the Analog Output Block (AO).

SP-PV Track in Man Permits the Set Point to track the process variable when the tar-

get mode of the block is Man.

SP-PV Track in LO Permits the Set Point to track the process variable when the

actual mode of the block is LO.

SP Tracks RCas or

Cas if LO or Man (SP

Track retained target)

In LO mode, SP is set to RCAS IN if target mode is RCas. SP is

set to CAS IN if target mode is Cas.

Increase to close Indicates whether to invert the output value before it is communi-

cated to the TB I/O channel. Inverts the SP signal before passing

it to OUT.
