Description
Use Autotune model request for CV3 - PV2. Set
True to replace the current model parameters
with the calculated Autotune model parameters.
The function block resets the input parameter to
FALSE.
Abort Autotune request for CV1. Set True to abort
the auto tuning of CV1 output for both PV1 and
PV2. The function block resets input parameter to
FALSE.
Abort Autotune request for CV2. Set True to abort
the auto tuning of CV2 output or both PV1 and
PV2. The function block resets input parameter to
FALSE.
Abort Autotune request for CV3. Set True to abort
the auto tuning of CV3 output or both PV1 and
PV2. The function block resets input parameter to
FALSE.
Description
Indicates if instruction is enabled. Cleared to false if
any one of CV1EU, CV2EU or CV3EU overflows.
Scaled control variable output for CV1. Scaled by
using CV1EUMax and CV1EUMin, where CV1EUMax
corresponds to 100% and CV1EUMin corresponds to
0%. This output is typically used to control an
analog output module or a secondary loop.
CV1EU = (CV1 * CV1EUSpan / 100) + CV1EUMin
CV1EU span calculation: CV1EUSpan = (CV1EUMax
– CV1EUMin)
Scaled control variable output for CV2. Scaled by
using CV2EUMax and CV2EUMin, where CV2EUMax
corresponds to 100% and CV2EUMin corresponds to
0%. This output is typically used to control an
analog output module or a secondary loop.
CV2EU = (CV2 * CV2EUSpan / 100) + CV2EUMin
CV2EU span calculation: CV2EUSpan = (CV2EUMax
– CV2EUMin)
Scaled control variable output for CV3. Scaled by
using CV3EUMax and CV3EUMin, where CV3EUMax
corresponds to 100% and CV3EUMin corresponds to
0%. This output is typically used to control an
analog output module or a secondary loop.
CV3EU = (CV3 * CV3EUSpan / 100) + CV3EUMin
CV3EU span calculation: CV3EUSpan = (CV3EUMax
− CV3EUMin)
