Notes regarding the table:
● In the table, "x" stands for the byte offset in the area; "y" for the bit number in the byte; and
"z" for the data block.
● The bold data type is the default data type in each case and does not have to be specified
when addressing. In addition, the specifications DB2.DBB5.BYTE and DB2.DBB5 are
equivalent, for example.
● Square brackets are used to access arrays, e.g. "/Plc/DB5.DBW2:[10]" (word array of length
10).
● Access to STRING arrays ("/Plc/DB123.DBB0:STRING[5]") is not supported.
