Integer limiter.
Minimum and maximum limiter for integer value.
| RtBody attributes pwr_sClass_ILimit | |||
|---|---|---|---|
| Int32 | Max | Max | Specifies the current value of the high limit. |
| Int32 | In | In | Specifies the current value of the input signal. |
| Int32 | Min | Min | Specifies the current value of the low limit. |
| Int32 | ActVal | Val | if In < Min and Min < Max ActVal = Min if In > Max ActVal = Max else ActVal = In |
| Boolean | High | hl | Specifies if a limitation upwards has taken place or not. FALSE means no limitation upwards at the moment; TRUE means that the output signal has been limited upwards to the value of Max. |
| Boolean | Low | ll | Specifies if a limitation downwards has taken place or not. FALSE means no limitation downwards at the moment; TRUE means that the output signal has been limited downwards to the value of Min. |
