Path-based acceleration/deceleration in the RFGPH1 function block (elimination)

Eliminated from:
EVS93xx-EK V8.1, EVS93xx-CK V8.1

Behaviour of the new version?
In the new version, the RFGPH1 function block considers value changes at the RFGPH1-IN input if RFGPH1-RFG-0 = FALSE is set and the RFGPH1-OUT output approaches the RFGPH1-IN input value.




What happens?
The RFGPH1 function block does not act as described in the documentation. Neither the requested final value is reached at the RFGPH1-OUT output nor is the selected distance at RFGPH1-DIST input adhered to.

When does the problem occur?
The problem occurs when the path-controlled  ramp adjustment (RFGPH1-T/DIST = TRUE) is used and if the input values at RFGPH1-IN are changed during a running adjustment process.

Which products/versions are affected?
EVS93xx-EK <= V7.1, EVS93xx-CK <= V7.1

Possible diagnostics?
The signal at the RFGPH1-OUT function block does not reach the setpoint selected (RFGPH1-IN input).

Short-term measures/recommendations?
The time-controlled ramp function instead of the path-controlled ramp function is to be used in the RFGPH1 function block (RFGPH1-T/DIST = FALSE).

Evaluation:
Not critical in terms of function since the display value is affected only.
