Any variable from a device on the network can be displayed on the 3051S LDC but the variable must be on a regularly scheduled communications cycle and the variable must be linked to a block within the 3051S. A typical configuration to do this is to link the output of the function block of the variable to one of the unused inputs of the Input Selector Block.
The 3051S LCD is equipped with a bar graph along the top portion of the display screen. The bar graph will display the percent of range of AI.OUT (see Figure
The bar graph on the LCD can be enabled from the DISPLAY_PARAM_SEL parameter in the LCD block.
If no AI block is found to be configured for Channel 1 the bar graph (including annunciators) will remain blank. If more than one AI block is found to be configured for the Channel 1 the AI block with the lowest OD index will be used to calculate the bar graph value.
The following equation is used to calculate the percent of range of AI.OUT:
Figure
Bar Graph Value = 100 * (AI.OUT – AI.OUT_SCALE @ 0%)
(AI.OUT_SCALE @ 100% – AI.OUT_SCALE @ 0%)
If the bar graph value calculation returns a value less than 0%, the LCD will display a bar graph value of 0%.
If the bar graph value calculation returns a value greater than 100%, then the
LCD will display a bar graph value of 100%.
