Re: In our plant the operator select an C:B.P with $PICK1 an then he will change the value. So it isn't possible to give the right range for each Point. The correction configuration approach is to configure the pick point with the range. So, instead of configuring C:B.P, you would configure C:B.P|R=<low>,<high>. I will admit that this could be a lot of work if you have a lot of displays to update. You could use d_edit (DM) or dedit (FV) to make the change more quickly. Other than this approach, I'm not aware of anything in FV/FD to do what you want.

I try to describe it better: In our plant the operator select an C:B.P with $PICK1 an then he will change the value. So it isn't possible to give the right range for each Point. I am looking for an solution that only increase/decrease (any value) with an fix value. Like +/- 0.5. And it doesn't care if we have %, =B0C, t, m=B3/h, .... or what ever.

The Range Variables (Rxy) parameters are OM objects that contain 3 = floating point values. Rxy[0] - High scale - HSCxy Rxy[1] - Low scale - LSCxy Rxy[2] - Change Delta - DELTxy The DM/FV is smart enough to set the big (double arrow) and small = (single arrow) ramp buttons to a percentage of the span IF the Rxy parameter is specified on the tag name, e.g., C:B.SPT|RI1 Might be used for a PIDA block setpoint ramp. If the Rxy parameter is not specified, a default is assumed and the RAMP Buttons will use a percentage of that span. If you want a custom span, you can specify it as follows: C:B.P|R=3D<lowRng>,<hiRng> So, try this: Make a graphic that contains a rectangle. Configure the select action = ramp with the following line: =20 C:B.SPT|R=3D2.0,98.0 Protection Class: 0 +/- percent control range: 5 Where C:B.SPT refers to some PID block setpoint in your system. This configuration will clamp the .SPT between 2.0 and 98.0 Obviously = the custom range should be within the block's RI1 (LSCI1,HSCI1) ****** Thanks to Leo Moramarco/FoxCanada and Ignacio Queirolo = Olivera/Repsol for some of the material above.

I want change the value of an given C:B.P. The value should change up/down from current value. For example in +/-0.5 steps (newvalue =3D3D oldvalue + 0.5) The ramp function isn't the right function. Because the C:B.P increase by percent of the control range. Has anybody an easy solution for this small problem?
