Subcode

R

An enumeration specifying the cause of the alert to be

reported.

Other

Setting:

Other: Non-specific error active

BlockConfiguration: Error detected in block configuration

LinkConfiguration: Error detected in link configuration

SimulationActive: Simulation enabled in this block

LocalOverride: Output tracking or faultstate active

DeviceFaultState: DeviceFaultState

DeviceMaintenance: Device needs maintenance soon

InputFailure: Process variable has bad status

OutputFailure: Failure detected in output hardware

MemoryFailure: Memory error detected

LostStaticData: Static parameters cannot be recovered

LostNVData: Non-Volatile parameters cannot be recovered

ReadbackCheck: Failure detected in READBACK

MaintenanceNeeded: Device NEEDS maintenance NOW

PowerUp: Recovery from power failure

Value

R

The value of the associated parameter at the time the alert

was detected.

0

Setting:

0...255

Bypass

Bypass

Bypass

RW

The normal control algorithm may be bypassed through this

parameter. When bypass is set, the setpoint value (in percent)

will be directly transferred to the output. To prevent a bump

on transfer to/from bypass, the setpoint will automatically be

initialized to the output value or process variable, respectively,

and the path broken flag will be set for one execution.

Uninitialized

Setting:

ON: normal control algorithm bypassed, output based on
setpoint

OFF: normal control
