Modes

The AI Function Block supports three modes of operation as defined by the MODE_BLK
parameter:
•
•
•
12
0
lists conditions reported in the BLOCK_ERR parameter. Conditions in italics
Condition Name and Description
Other
Block Configuration Error: the selected channel carries a measurement that is incompatible with
the engineering units selected in XD_SCALE, the L_TYPE parameter is not configured, or CHANNEL
= zero.
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.
Memory Failure
Lost Static Data
Lost NV Data
Readback Check Failed
Device Needs Maintenance Soon
Power Up
Out of Service: The actual mode is out of service.
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 configurable parameters. The target
mode of a block may be restricted to one or more of the supported modes.
