BYPASS (Scaling, Tuning)
Allows the normal control algorithm to be bypassed. If control is bypassed,
the PID uses its setpoint value in percent of scale as its output value and
does not attempt to do any PID control.
Note The CONTROL_OPTS Bypass Enable option must be selected.
Device Needs Maintenance Soon 0x0040 The device is reporting performance
degradation that will soon require
maintenance.
Input Failure/BAD PV Status 0x0080 Either the input transducer channel has
reported a failure, or the input parameter
from an upstream block has reported a
failure. For an AI block, this could be
caused by an open circuit being detected on
the FP-AI-100 input module.
Output Failure 0x0100 The output transducer channel has reported
a failure. For an AO block, this could
indicate that the FP-AO-200 cannot drive
the current request, perhaps due to an open
circuit.
Memory Failure 0x0200 The storage for nonvolatile and static
parameters was corrupted.
Lost Static Data 0x0400 The device was unable to restore the values
of static parameters after a restart.
Lost NV Data 0x0800 The device was unable to restore the values
of nonvolatile parameters after a restart.
Readback Check Failed 0x1000 The value read back from the output
channel does not match the value the
output channel was set to.
Device Needs Maintenance Now 0x2000 The device needs to be maintained now.
Power-Up 0x4000 The device has just powered up.
Out of Service 0x8000 The block is currently out of service.
