I have project in TIA Portal 15.1. It has 20 connections S7-1200/1500 and 9 connections S7-300/400.

I have licenses:

Industrial Ethernet SOFTNET-S7 License Basic

Industrial Ethernet SOFTNET-S7 License Lean

but system don't use its.

After reboot PLCs a connection with them don't recconect.

What licences do we need for stable work the connactions or the problem is different?

Split from Industrial Ethernet SOFTNET-S7 License.

Hi,

For more than 8 connections between the Runtime and S7 controllers, you need to purchase a SOFTNET-IE S7 base license, which allows up to 64 connections. This is indicated in the FAQ below:

Licenses for WinCC TCP/IP Communication

Hi again,

No need, just the new license in the ALM.

Hi,

Yes, that is the license that allows up to 64 connections between Runtime and S7 CPUs. There is no difference between V15 and V15.1 licenses, so you should have no problem. However, please contact your usual Siemens sales contact for this.

I decided this problem. I installed Simatic NET and problems with connections finished.
