I supposed that, but in my application I have a percent control range of 5.0 and when I pick the ramp the variable goes 0.5 from the last value. If the DM assumed this percentage (5.0) of the 0-100 span, I think that the variable would move 5.0 not 0.5 from the last value because is the 5 percent of 100. Am I right?

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.,=20 C:B.SPT|RI1 Might be used for a PIDA block setpoint ramp. If the Rxy parameter is not specified, 0-100 is assumed and the RAMP = buttons will use a percentage of that span. Does this help?
