以下的测试将说明如连接远程的数据库：plcjs.技.术_网
Topic One: ODBCW1WW_P4LCJS_COM－PLC－技.术_网
Testing environment:WW.W_PLC※JS_C,OM－PL,C－技.术_网
Primary PC with a WinCC, This PC, we named is Server.——可——编——程——控－制－器－技——术——门——户
Secondary PC with a Access DB, This PC, we named is Client.WWW_PL※CJS_COM－PLC－技.术_网
Server PC and Client PC is connected by Ethernet.WWW_P※LCJS_COM－PLC－)技.术_网
Test step:WW.W_PLC※JS_C,OM－PL,C－技.术_网
1. The Server PC and the Client PC must config the DB server option. This is a veryWW.W_PLCJS_COM－PLC－技.术_网
important ODBC configuration step.P.L.C.技.术.网——可编程控制器技术门户
Control Panel -> SIMATIC Workstation -> Workstation Configuration -> TCP/IPWWW_PLCJS_COM－PLC－技.术_网
Configuration for Multiple Node Systems -> select the DB server option.WW.W_PLC※JS_C,OM－PL,C－技.术_网
2. At the server PC node, active the WinCC project but do not running this project(This actionWWW_PLCJ－S_COM－PLC－技.术_网(可－编程控－制器技术－门户)
is only for the first time ODBC configuration at the client PC) . WinCC will build two ODBCWWW_PLCJS※COM－PLC－技×术_网(可编程控※制器技术门户)
driver connections automatically, one is for RT Database and the other is for RC Database.WW.W_PLCJS_COM－PLC－技.术_网
For example: "CC_u1_01-04-12_15:36:08R","CC_u1_01-04-12_15:36:08".WWW※PLCJS_COM－PL＃C－技.术_网(可编※程控※制器技术门户)
All of the jobs is over at the server PC node.WWW.PLCJS.COM——可编程控制器技术门户
3. At the client PC node, open the contol panel folder and select the "Sybase SQLWWW_PLCJS※COM－PLC－技×术_网(可编程控※制器技术门户)

Database File: \\Bjadlijs\WinCC50_Project_u1\u1RT.db (the "WinCC50_Project_u1" is aWWW_PL※CJS_COM－PLC－技.术_网
share directory by WinCC automatically and the "u1RT.db" is the WinCC RT database name.WWW※PLCJS_COM－PL＃C－技.术_网(可编※程控※制器技术门户)
youd better search the "u1RT.db" file via the Browse button.)WW.W_PLCJS_COM－PLC－技.术_网
At this time, we completed the ODBC configuration.WWW_PLCJS_COM－PLC－技.术_网
4. At the server PC node, Running the WinCC project( Dont forget to select the Tag LoggingWWW※PLCJS_COM－PL＃C－技.术_网(可编※程控※制器技术门户)

5. At the client PC node, you could open an Access and import or link forms via an ODBCP_L_C_技_术_网——可——编——程——控－制－器－技——术——门——户
