5391/Ordinal Meter - RG354703
L5391/Ordinal Meter - RG354703

Description

This block mimics a meter is a display band on an L5391 operator station.

Similar to the L5391/Meter function block, this block displays an ordinal between 0 and 32767 rather than a scaled value.

In order to be displayed, this function block must be specified in either a page handler or display handler function block.

For example:  If the meter is to display total material in feet. This display must range from 0 to 4800 feet with a redline at 3000 feet.  The format string is ##### Feet, the display max is 4800, the high redline is 3000 and the low redline is 0.

A number of parameters are required to set up the meters display, these are described below.

Parameters

Measured Value	Input to the meter.  Expects an ordinal (0 to 32767).

Get Measured Value	Returns the current number displayed on the meter:  0 to 32767.

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

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

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

# is used to indicate a digit position.

Other than this special character, the string may contain unit legends, etc.  Five digits are normally specified.

Display max	This defines the maximum measured value that may be displayed on the analog mimic part of the display.  (0 to 32767).

High redline	This is equivalent to the redline on conventional meters.  If the measured value exceeds the high limit, the display pointer is highlighted.  (0 to 32767).

Low redline	This is equivalent to the redline on conventional meters.  If the measured value falls below the high limit, the display pointer is highlighted.  (0 to 32767).
