 **S7 Arrays**
-An S7 Array is configured with the size and type of the array using the type of data read in the address. In the example
+An S7 Array is configured with the size (Register Count) and starting register (Start Register), and the data type of the array is taken from the address designation. In the example
-{{:pasted:20210131-232432.png}}
+{{:pasted:20210131-232432.png?400}}
-The data type is "B" in the starting address DB195:B0, and the number of elements in the array is 6. This means that the S7Array will read 6 byte registers starting at DB195:B0, so DB195:B0,DB195:B1,DB195:B2,DB195:B3,DB195:B4,and DB195:B5.

If the Start Register was set to read words, such as DB195:W8, and the array size was set to 3, DB195:W8,DB195:W9,and DB195:W10 would be returned in the array.
