Table 8-26: BLOCK_ERR Conditions
Condition
number
Condition name and description
0 Other
1 Block Configuration Error: The BY_PASS parameter is not configured
and is set to 0, the SP_HI_LIM is less than the SP_LO_LIM, or the
OUT_HI_LIM is less than the OUT_LO_LIM.
2 Link Configuration Error
3 Simulate Active
4 Local Override: The actual mode is LO.
5 Device Fault State Set
6 Device Needs Maintenance Soon
7 Input Failure/Process Variable has Bad Status: The parameter linking to
IN is indicating a Bad status.
8 Output Failure
9 Memory Failure
10 Lost Static Data
11 Lost NV Data
12 Readback Check Failed
13 Device Needs Maintenance Now
14 Power Up
15 Out of Service: The actual mode is out of service.
8.9.6 Modes
The PID function block supports the following modes:
• Manual (Man): The block output (OUT) may be set manually.
• Automatic (Auto): The SP may be set manually, and the block algorithm
calculates OUT.
• Cascade (Cas): The SP is calculated in another block and is provided to the PID
block through the CAS_IN connection.
• RemoteCascade (RCas): The SP is provided by a host computer that writes to
the RCAS_IN parameter.
• RemoteOutput (Rout): The OUT is provided by a host computer that writes to
the ROUT_IN parameter.
• Local Override (LO): The track function is active. OUT is set by TRK_VAL. The
BLOCK_ERR parameter shows Out of service.
• Initialization Manual (IMan): The output path is not complete (for example, the
cascade-to-slave path might not be open). In IMan mode, OUT tracks
BKCAL_IN.
