I want to retrieve OPC UA data with a Flexy 205 from a robot controller (OPC UA server).
I have setup the I/O server in the Flexy. Connection is OK.
Tag configuration is also working for NONE array types.

My problem is with the array tags. Configuration seems OK: ns=1;pos=7;s=R1:X1[32..63]
Updating my tag gives a 'unknown' error.

Removing the pos=7; will remove the error and result in Value = 1.
Why is my array index, pos=7 not working?
The tag I am configuring consists of a boolean array[32].

Another tag I testen, a integer array[500], gives the same 'unknown' result.
Removing the pos=..; is also removing the error. Value = 500 is the result.
Here without the array index the result seems to be the array dimension.

In the attachment I have some pictures configuring the tag and a screenshot of UaExpert.

Please help.

Best regards,
Rik

Hi Rik,

Indeed, Array may not work... I do not remember that we have already tried that (at least in the support team)
I see in UAexpert that you are polling the whole array and not array element.
Can you poll an array element separately ?

Can I have more details about the controller (brand / model)?

Hello Simon,

Robot brand is OTC Daihen, model of controller is FD-19.
We cannot poll for seperate array element.

You mention 'Array may not work' but I can choose the Array Element Index: 'pos=..'
Is it possible that the development of the support of arrays is started, but not finished/ tested yet?

Maybe I can solve the issue by using Java. Is OPC UA functionality supported in java 1.4?

Best regards,
Rik

Hello Simon,

Did you already try the array functionality? Functionality is certainly in Flexy, but not working correctly.

We tried to solve it in Java, but OPC UA is newer than de java version in the Flexy.

Is this issue handled by the next firmware of the Flexy?
