Greetings everyone,
my problem occurs in using a Bachmann M1-Device to set up a robot control. The control is implemented in Simulink and built to the device using automatic code generation, which works flawlessly. In order to test some things out, i wrote a .m-file to basically simulate the robot. Im using the OPC UA commands to read from and write to the control-programm on the device. Therefore, i specified SVI-Read and SVI-Write Blocks in the Simulink file.
I establish a connection using
uaClient = opcua(IPAdress,Port)
connect(uaClient)
Im then creating the node-objects to read and write values with
node_q_lin = findNodeByName(Namespace,'hOPCUAq_lin','-once')
.
AccessLevelCurrent: read/write
.
In Simulink, hOPCUAq_lin is a SVI-Read Block. Data type is specified as inherited, initial value is set to [0 0 0 0 0]. Reading from the node delivers
readValue(uaClient,hOPCUAq_lin)
=[0 0 0 0 0].
So far, so good. But if i try to write a value into the node with, the following error occurs
writeValue(uaClient,node_q_lin,[0 0 0 0 0])
Error using opc.ua.Client/writeValue (line 1268)
The value supplied for the attribute is not of the same type as the attribute's value.
This seems quite strange to me, and i don't really have a clue to what went wrong here. I have not found a similar scenario in the documentation so far, but i will keep on looking. I would greatly appreciate any suggestions.
