XY Graph reflects the correlation of two variables visually. If you want to monitor the XY
Graph reflecting the changes of address values, the NB Unit can clearly displayed it out only by using
this component.
When the sampling number with M channel per page is set to N, the values are stored to the PLC, e.g.
X11, Y11, X12, Y12, ..., X1N, Y1N, ..., XM1, YM1, ..., XMN, YMN. The number of the memory
addresses occupied by the PLC is M×N×2.
Note
For “Xij, Yij”, subscript “i” represents the channel number, “j” represents the sampling point, and “Xij”
represents the coordinate position of X for sampling point j in channel i.
Process of adding one XY Graph component
1
Press the XY Graph component icon, drag it to the screen, then the [Basic Properties] dialog
box of XY Graph component will pop up.
Read Address:
Specifies the word address of PLC corresponding to the data of X-axis trajectory,
and the word address corresponding to Y-axis is “read a 1”. If the channel
number is greater than 1, the addresses corresponding to the 2nd channel are as
follows: “read a2 × sampling points” for X-axis and “read a 2 ×
sampling point +1” for Y-axis and so on.
Address:
Refers to the first address of the word address corresponding to XY Graph.
Data Format:
Includes BIN or BCD.
Word Length:
It is determined by the channel number, sampling points, and the type of selected
type of storing. The word length cannot be changed manually.
