OpStn/Clamped Pot - RG354249

Description

This block mimics a potentiometer in a display band on an L5101/L5102 operator station.  It has a single Output.  Pressing the buttons on the right side of the display changes the value of the Output

In order to be displayed, the pot must be specified in the OpStn/Display Handler function block.

The Legend is a single line of up to about 16 characters and may be Highlighted (HL) or blinked.  Both a High Clamp and a Low Clamp must be specified as configuration parameters.

Note that a pot requires feedback from its Output to its Setpoint (SP) input.  The clamped pot has a predefined feedback connection which may be deleted during configuration if necessary.

A number of parameters are required to set up the clamped pots display.  Here are some examples:

Example 1:	(This is the sample function block drawing.)  The clamped pot is to display the line speed in feet per minute and 100% setpoint corresponds to 600 feet per minute.  The setpoint cannot be negative. The format string is ###.# FPM and the gain is 6000.

Example 2:	The clamped pot is to display motor speed in RPM and 100% corresponds to 1750 RPM.  The format string is -#### RPM and the gain is 1750.

Example 3:	The clamped pot is to display roll length in meters and 100% setpoint corresponds to 60,000 meters.  The format string is ####0 meters and the gain is 6000.

Parameters

Setpoint	Feedback to the pot.  Expects a value (-100% to +100%).

Highlight	Selects the highlighting mode.  Expects an ordinal (0 to 2) where 0 means no highlight, 1 means highlight, and 2 means blink.

Get Setpoint	Returns the current setpoint:  -100% to +100%.

Legend	A string of approximately 16 characters may be specified for the legend.

Format	A format string specifies how the setpoint will be displayed in the digital readout part of the display.  This is done through the used of special characters.

# is used to indicate a digit position.

- is used to indicate the position of the sign.

. is used to indicate the position of the decimal point.

Other than these special characters, the string may contain unit legends, etc.  Up to five digits may be specified and the decimal may be placed anywhere within them (or omitted).

Gain	This defines the on-display representation of 100% setpoint; it may range from 10 to 10 000.  Note that the decimal point should be ignored when determining gain; its position is specified in the format string.
