OpStn/Meter & SP Monitor - RG354424

Description

This block displays a measured value along with a setpoint in a single display band on an L5101/L5102 operator station.

The Meter & SP Monitor can be in either the meter mode or the Setpoint (SP) monitor mode.  Switching between the two modes is accomplished via the Mode (MD) logic input.  In the meter mode, the measured value legend is shown and the digital part of the display indicates Measured Value (MV).  In the setpoint monitor mode, the setpoint legend is displayed and the digital part of the display indicates Setpoint.  In both modes, the upper pointer indicates Setpoint and the lower pointer indicates Measured Value.

In order to be displayed, the Meter & SP Monitor must be specified in the OpStn/Display Handler function block.

The function block has a logic Press output which is true when the touchscreen area associated is pressed and false when it is not pressed.

Parameters

Measured Value	Measured value input.  Expects a value (-100% to +100%).

Get Measured Value	Returns the current measured value:  -100% to +100%.

Setpoint	Setpoint input.  Expects a value (-100% to +100%).

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

Mode	Mode selection input.  Expects meter (false) or monitor (true).

Get Mode	Returns the current mode:  meter (false) or monitor (true).

MV Legend	A string of up to approximately 16 characters may be specified.

SP Legend	A string of up to aprroximately 16 characters may be specified.

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.

- 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% measured value; it may range from 10 to 10 000.  Note that the decimal point should be ignored when determining gain; it is in the format string.

Display max	This defines the maximum measured value that may be displayed on the analog mimic part of the display.  (-100% to +100%).

Display min	This defines the maximum measured value that may be displayed on the analog mimic part of the display.  (-100% to +100%).

High redline	This is equivalent to the redline on conventional meters.  If the measured value exceeds the high limit, the display pointer is highlighted.  (-100% to +100%).

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.  (-100% to +100%).
