Using the following group of parameters allows to define a filtering method of analog inputs and outputs - AI Ai, AOAo, CICi, COCo, TiR, ToR.
New time => new value
...
The system will assign a value (it is defined by selecting the particular button) to particular I/O tag anly only after it is unchanged during defined time [s].
...
Conversion to technical units may be defined for analogue and cardinal inputs and outputs - AI, AO, CI and COAi, Ao, Ci, Co, TiR and ToR.
| Conversion type | Conversion formula |
|---|---|
| None | - |
| Linear | Output = A * Input + B |
| Polynomial | Output = A * Inputn *B x Input + C |
| Pt 100 | Output = a = -5.802E-05 |
| Simatic S5Time | Conversion of the Siemens Simatic relative time structure. |
...
Logical polarity of the I/O tag is adjusted for digital I/O tags - DIDi, DODoout.
- Normal - an I/O tag value is not to be changed.
- Inverse - an I/O tag value is to be inverted.
