Simulink OPC Read: Invalid Item ID

Hi!

I'm trying to read data from an OPC server in Simulink using the OPC Read Block of the OPC Toolbox.

Connecting to the servers is working fine, but I'm struggling to add an server item.

The item ID is: CP_Lokal.XXXGroupName.DB14,REAL136

By using a semicolon, Simulink is executing an automatic line break (since you seperate items by suing a semicolon), so I end up having to items in my item list, which are invalid:

(i) CP_Lokal.XXXGroupName.DB14

(ii) REAL136

I've tried the same in Matlab, in order to check the item ID and there it's working

da = opcda('xxxxxxx', 'ArchestrA.DASSIDirect.3');
connect(da);
grp = addgroup(da, 'TRO');
set(grp, 'UpdateRate', 10);
itm = additem(grp, 'CP_Lokal.XXXGroupName.DB14,REAL136','double');
r = read(itm);

Does anyone have a clue, how to solve this problem?

Thanks in advance,

Stefan

Struggling with the same problem. I want to create new Items without using the factory items. Do you handle the problem?
