7.11.8 Block Errors
Table 7-21 lists conditions reported in the BLOCK_ERR parameter. Conditions in italics
are inactive for the AI block and are given here only for your reference.
Table 7-21 BLOCK_ERR Conditions
Condition
Number
Condition Name and Description
0 Other
1 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.
2 Link Configuration Error
3 Simulate Active: Simulation is enabled and the block is using a simulated value in its execution.
4 Local Override
5 Device Fault State Set
6 Device Needs Maintenance Soon
7 Input Failure/Process Variable has Bad Status: The hardware is bad, or a bad status is being
simulated.
8 Output Failure: The output is bad based primarily upon a bad input.
9 Memory Failure
10 Lost Static Data
11 Lost NV Data
12 Readback Check Failed
13 Device Needs Maintenance Soon
14 Power Up
15 Out of Service: The actual mode is out of service.
7.11.9 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 configurable parameters. The target
mode of a block may be restricted to one or more of the supported modes.
