Assign the tags to draw a reference graph. You must assign real tags. A series of addresses according to the data count will be allocated starting from the assigned pen’s address. Since the reference graph needs X- and Y-coordinates, a single point requires two-word addresses. Therefore, the address addresses will be assigned as shown below.
...
In this tab, you may assign the tags to monitor in the Trend object. In the case of the an ST Trend, you may configure up to 8 pens. Each pen may display up to 2048 data points.

The data count tags are used to decide the number of consecutive addresses after the assigned pen. In other words, the number of data count tags used must be equal to the number of pens. The data count tags’ values must be an even number. If an odd number is assigned, 1 will be subtracted from the value and applied to the graph.

Item | Description |
ST-Control Bit | The assigned digital tag will display the state of data reception when the graph is updated. In the case of ongoing data reception, the assigned tag will be set (1). When the process is completed, the tag will be reset (0). |
ST-Control | Assign a tag to control the graph update of the ST Trend. The object will be updated according to the value assigned to the ‘ST-Control’. 1: Overwrites a new graph on the existing graph. 2: Clears the current graph. 3: Clears and redraws the graph. 4: Starts ‘Trace’ operation (does not operate if there is no reference graph). 5: Pauses ‘Trace’ operation (maintains the accumulated data). 6: Stops ‘Trace’ operation (does not maintain the accumulated data). |
ST-Trace Point | Assign a tag or an address to draw the Trace graph. When the tracing operation starts, up to 2048 tag values will be stored in the buffer and displayed on the graph. |
ST-Minimum Value | Assign a tag or an address to define the minimum value of the graph. If the minimum value is greater than the maximum value, the graph will not be updated. You can also select the ‘Using Fixed Val.’ option to manually enter the value. If the value is smaller than 0, the graph will not be drawn. |
ST-Maximum Value | Assign a tag or an address to define the maximum value of the graph. If the maximum value is smaller than the minimum value, the graph will not be updated. You can also select the ‘Using Fixed Val.’ option to manually enter the value. If the value is smaller than 0, the graph will not be drawn. |
ST-Trace Display Time Tag | Assign a tag to use as the X-Axis time display. This value will be applied when the reference graph is updated. Only the real part of the value is used. You can also select the ‘Using Fixed Val.’ option to manually enter the value. If the value is smaller than 0, the graph will not be drawn. |
