How can you establish a connection between a S7-1200 PLC and SIMATIC NET. As it is not possible to create a PC Station with STEP 7 Basic V10.5 you need to use the NCM PC tool of SIMATIC NET Edition 2008. Figure 1-1: 1.2 Requirements PG/PC STEP 7 Basic V10.5 SIMATIC NET Edition 2008 – NCM PC tool – OPC Server – OPC Scout S7-1200 PLC. 17 OPC Scout 17 OPC Scout With the OPC Scout, you can test an OPC application or commission the OPC server. The following description assumes that you are familiar with the terminology and mechanisms of OPC (OPC server and OPC client). You will find basic and detailed information on this topic in the Industrial Communication with PG/PC manual /1/.

Can anyone please advise me about OPC Array tags? I'm using SIMATIC NET OPC server, and CITECT OPC Client (the latest OPC Driver, V1.15.18.001). The single Tags work perfectly (much faster even then the S7NT Protocol). But not so with Array tags.I've tried to implement the instructions written in the CITECT driver help, and in KB articles, but couldn't get a result.
My definitions are:
I/O Device Protocol: OPC1 (as is advised by the 'Driver Help'. Since SIMATIC OPC address format contains '[')
Variable Tag: Data type – INT. Address - S7:[Connection_ID]DB450,INT768,18 (following the OPC.SimaticNET address format)
This array address was checked with SIMATIC's OPC Scout, and is communicating perfectly.
I've also tried the advised OPC parameters in my CITECT.INI file, and defined the arrays there. Again, with no success. Doe's anyone have a working example of the required proper definitions to get it going?
Thanks
