PV1/PV2Hyst:
Hysteresis
●
PV1/PV2WH_Lim
: Limit for high warning
●
PV1/PV2WL_Lim
: Limit for low warning
The result of limit monitoring is returned at the interconnectable output parameters:
●
PV1/PV2AH_Act
= 1: Limit for high alarm reached or exceeded
●
PV1/PV2AL_Act
= 1: Limit for low alarm reached or undershot
●
PV1/PV2WH_Act
= 1: Limit for high warning reached or exceeded
●
PV1/PV2WL_Act
= 1: Limit for low warning reached or undershot
Monitoring is always enabled using the input parameters:
●
PV1/PV2AH_En
= 1: Monitoring of the high alarm limits
●
PV1/PV2AL_En
= 1: Monitoring of the low alarm limits
●
PV1/PV2WH_En
= 1: Monitoring of the high warning limits
●
PV1/PV2WL_En
= 1: Monitoring of the low warning limits
The corresponding message is suppressed using the parameters:
●
PV1/PV2AH_MsgEn
= 0: Alarm (high) messages are suppressed
●
PV1/PV2AL_MsgEn
= 0: Alarm (low) messages are suppressed
●
PV1/PV2WH_MsgEn
= 0: Warning (high) messages are suppressed
●
PV1/PV2WL_MsgEn
= 0: Warning (low) messages are suppressed
You can define a hysteresis (
PV1/PV2Hyst
) for the limits, for example to suppress signal
flatter. You can also modify the limits and hysteresis via the faceplate.
Gradient monitoring
The gradient
PV1Grad
is calculated by means of a delay function configurable using
LagTime
.
During calculation of the gradient, jumps in the input value
PV1
are smoothed.
The peak values of the gradient are output in the output parameters
PV1GradNP
(negative
gradient) and
PV1GradPP
(positive gradient). These are reset when the operator enters the
corresponding command for resetting.
The slope of the gradient
PV1Grad
can be monitored for the following limits:
● Limit (high) for the positive gradient (
GradHUpLim
)
● Limit (high) for the negative gradient (
GradHDnLim
)
● Limit (low) for the absolute gradient (
GradLLim
)
Activation of the individual monitoring functions is carried out at the corresponding "Enable"
parameters, e.g.
GradHUpEn
for activating the high gradient limit for positive gradients
(
GradHUpLim
).
Reaching or violation of your defined limits is indicated at the corresponding "Active" output
parameters, e.g. by means of
GradHUpAct
= 1 for the limit (high) for the positive gradient.
