The following data types are supported:
- bool
- byte
- sint
- int
- dint
- real
- dword
- lint
- lreal
- string
- To access the bits of a dint tag, use the data type bool and append the bit address (.0 to .31) to the name of the dint tag.
- To access the elements of a two- or three-dimensional array, use multiple square brackets instead of commas to separate the indices. For example, if the array in RSLogix 5000 has the name MyArray with the data type dint[2,2,2], you can access the 0th index by entering MyArray[0][0][0] in Litmus Edge.
Refer to the following tag parameters in Litmus Edge.
