Note: syntax of address when specifying number of elements is compatible with Siemens S7 OPC server (e.g. Agreed S7 PDU size is minimum of size offered by D2000 (parameter S7 PDU Size) and supported size of specific device. If a smaller size of packet (S7 PDU size) is agreed on during establishment of connection, reading of this I/O tag will not be performed and trace file of line will contain an error message. 100 elements of type D (double word) are configured, it means reading of a block of 400 bytes. Note: All items elements are read at once. Structured I/O tags are not supported for objects of type T (timers), C (counters) and S (system status lists) nor for data type STRING. items) will be written to one item of destination column. Number of elements for structured I/O tags with configured Destination column. offset=10, length=20) represent "Order number of the module", e.g. S7-300 will answer to this request by a 36 byte-long string (bytes 0.35) in which bytes 10.29 (i.e.
