Answer

<Causes>

  1. No data is stored in the device memory address for each graph number.
  2. The number of points to plot is not specified in the control device memory.

 

<Solutions>

  1. Check if data is stored in the number of device memory addresses as specified for [Points to Display] starting from the device memory address specified for [Device] for each graph number.

    Example: [Points to Display]: 180, [Device] for graph No. 0: WM100
    Store data in WM100 to WM279.

     
  2. Check if the number of points to plot (1 to 1920) is stored in bit 0 to bit 10 of the control device memory.

    Example: Control device memory: WM5000, number of plotted points: 180
    Specify the number of points to plot (180) in bit 0 to bit 10 of WM5000.
