6.3.8 XY Plot

Introduction

The real time data in cache will display as continuous curve or separated points, each point in XY plot needs 2 addresses to set a point.

Description

1) Source

Auto sample: Select data from [XY plot] and displayed in a curve according to the set time;

Trigger Sample: When the trigger address is set, the data is collected and displayed in a curve. After the data is collected, the trigger address is automatically reset;

Curve settings: According needs to set style and color for each curve.

Read address: *for example, PLC word address is D, it points number is m. (point numbers no more than 800);

Word address D is the X coordinate of the first point

Word address D+1 is the Y coordinate of the first point;

Word address D+2 is the X coordinate of the second point;

Word address D+3 is the Y coordinate of the second point;

......

Word address D+2m-1 is the X coordinate of the mth point;

Word address D+2m is the Y coordinate of the mth point;

Because if the number of XY points is m, it is necessary to continuously read 2m words from the address D of the PLC to draw a complete XY picture.

Quick setting: Fill in the starting address, according to the parameter settings, automatic allocation of addresses.

2) Range

Variable: The data range for the graph could be set as a variable;

X, Y Limit: Set the max and min value of displaying curve;

Result

When all configurations are completed, when the HMI is running, it displays as shown below.
