Single access when writing to field elements using 'IndexRange'
Determines whether write access to a field element writes the entire field back to the communication component.
According to the OPC UA specification, individual field elements of simple data types can be described via an index. The IndexRange function was introduced to improve data consistency and the performance of write operations. However, in some OPC UA servers it leads to an undefined error in the OPC UA server and in the PLC. If the OPC UA server exhibits this incorrect behaviour, you can deactivate this option.
