I am trying to read data from PLC via OPC server provided by Rockwell Automation using "opc read block of simulink". When I browse tag on my OPC sever, its navigation list is as shown below:
>opc server name
>> offline
>> online
>>>input1
>>>INPUT2
But when I am browsing in OPC read toolbox, when I click on "online", I am not able to navigate down to input1. It shows that " name space browsing is not available". How can I rectify this problem and navigate further in the list??

Hello,
if the OPC-Server is not local on your computer and runs on the "older" protocol OPC-DA, the dcom configurations of the server and the client have to be configured.
For more info go to https://de.mathworks.com/help/opc/ug/troubleshooting.html or search for "dcom configuration" on google.
