I have to port a opc-da server to opc ua using embedded SDK.
In opc-da server arrays with 2 dimensions are used.
I did not find a way to define such arrays with embedded SDK.
As far as I can see the OPC-UA standard says that a variable should have a ValueRank and ArrayDimensions as member.
In embedded SDK Variable seems to allow an array with only 1 dimension
typedef struct {
UA_Base_t base_config;
UA_Value_type_t value_type;
uint32_t max_array_length;
uint16_t user_read_permissions;
uint16_t user_write_permissions;
} UA_BaseDataVariable_t;
Question: Is there a way to have arrays with 2 dimensions ?
Thank you !

Hello Franz,
This is a feature that is not currently exposed in our API but we could add it. The API is designed for ease of use primarily so much of the complexity of UA is hidden from the application developer.
Is this feature an important requirement for you?
Regards,
Liam.

Hello Liam,
I think there will be a workaround for me to avoid 2-dimnsional arrays but it is annyoing and I did not expect to lack a feature that I had with our 15-year-old opc-da sdk.
Kind regards
Franz

Hi Basavraju,
in your post 4 month ago you announced a new release for July with 2 dimensional array feature.
Did this happen or did I miss it ??
Regards
Franz
