[HELP] CitectSCADA S7NT Driver limitation?

[af.naderi]

Hi every body,

I have a big problem with CitectSCADA and SIMATIC Net.
I must communicate between Citect and about 20 SIEMENS PLCs ( S7-300 and S7-400), so i follow instructions and create connections. every thing is good until eleventh connection. Citect can't communicate more than ten Siemens PLC.

Now, i want know:
1- Is there any limit on the number of connections between Citect and Siemens PLCs (or between Simatic Net and Siemens PLCs)?
2- If "YES", What can i do?

Additional notes: I use CitectSCADA version 7.2 SP1 Demo license and SIMATIC Net version 5.4 full license.

Best regards

CitectSCADA Knowladgebase. Q3784 Configuring CitectSCADA Projects for Optimal Communication to Siemens S7 PLCs Using the S7 Driver: "...The Siemens Softnet V6 only allows a maximum of 10 connections or "channels" for external applications such as Citect. It can however support up to 64 Devices/PLC's to be shared among these 10 connections. If you require more than 64 PLC's on a single I/O Server, you can alternatively use the PSDIRECT driver."
