Hi all list, I am trying to install an aim* OPC server DA on a windows 2003 server PC (hostid=opc_test). It should retrieve the real time data from an AW70 (Win NT) which has installed AIM*AT. During the installation of the OPC software on the opc_test I have installed also the aim*api admin tool in the same PC. Starting the api admin tool I should find the AW70 host id in the server list (because of broadcasting). But I did not find it. I can ping the two PCs so I can be sure that there is connection between them. Even configuring the data server connection manually in the "EDIT SERVER CONNECTION" button of the opc_test machine, I cannot see the AW70 in the server list. Is it because I have still not licensed the opc_test in the AW70? If I open the authorization tag by using the api adm of the AW70 (which has aim*at server installed) it does not appear the package name "OPCDAO" which I have in the opc_test. I think there appear only the packages installed on the machine. BUT I HAVE TO LICENSE THE OPC SERVER WHICH IS INSTALLED ON THE OTHER PC. How can I then license, in the data server, the OPC (opc_test) machine? After licensing that, user accessing, security etc as written in the manual, will I able to see the RTPs of the AW70 by using the matrikon opc explorer? Please help me.
