Write Arrays

  1. In System Browser, select the view that includes the OPC UA adapter.
  1. Expand the OPC UA adapter subtree, and select the array object that you want to modify.
  • In the Extended Operation tab, the corresponding values display next to the Value property. Multiple array element values are separated by empty space.
  1. To adjust array values, next to the Value property, click Write.
  • Index and Value fields becomes available for you to set array values by specifying a numeric index followed by an alphanumeric value.
  1. To modify one of the values in the array, do the following:
    a. Identify its zero-based index in the array (for example, 0 for the first position, 1 for the second one, and so on) and enter this number in the Index field.
    b. Enter the desired value in the Value field.
    c. Click Send.
  • The array value is updated accordingly.
  1. To add a new value to the array, do the following:
    a. In the Index field, enter a numeric value higher than the last index in the array (for example, the last element has index 4, and you enter any value higher than 4).
    b. Enter the appropriate value in the Value field.
    c. Click Send.
  • The new value is added to the end of the array.
