Modes
The AI function block supports three modes of operation as defined by the
MODE_BLK parameter.
•
Manual (Man): The block output (OUT) may be set manually.
•
Automatic (Auto): OUT reflects the analog input measurement or the simulated
value when simulation is enabled.
•
Out of service (O/S): The block is not processed. FIELD_VAL and PV are not
updated, and the OUT status is set to Bad: Out of Service. The BLOCK_ERR
parameter shows Out of Service. In this mode, you can make changes to all
156
lists conditions reported in the BLOCK_ERR parameter.

Link configuration error.
Simulate active: Simulation is enabled, and the block is using a
simulated value in its execution.
Local override.
Device fault state set.
Device needs maintenance soon.
Input failure/process variable has bad status: The hardware is bad, or a
bad status is being simulated.
Output failure: The output is bad based primarily upon a bad input.
