I need to write my own program using C#.NET and connect to S7 CPU via Simatic.NET OPC server. So I allways thought that I need SOFTNET license. Now I look at catalog and see that there is OPC server licenses. What is that? What really license do I need?
	Best regards, Darius

So you use SOFTNET you don't need the hardnet licenses (Only necessary when using a special CP like CP5613, CP1623, etc.) Everything below is based on SIMATIC NET 2008. Profibus: SOFTNET S7: 6GK1704-5CW71-3AA0 S7 Communication over ProfiBus SOFTNET-DP: 6GK1704-5DW71-3AA0 PROFIBUS-DP S5-compatible communication(FDL) SOFTNET-DP Slave: 6GK1704-5SW71-3AA0 PROFIBUS-DP (slave) Industrial Ethernet: SOFTNET S7:6GK1704-1CW71-3AA0 S7 communication S5-compatible communication(SR) Max. 64 Connections SOFTNET S7 Lean: 6GK1704-1LW71-3AA0 S7 communication S5-compatible communication(SR) Max.8 Connections ProfiNet: PN IO OPC Server: 6GK1704-1HW71-3AA0 PC with regular Ethernet card will function as PN IO Controller PN CBA OPC Server: 6GK1706-0HB71-3AA0 ProfiNet CbA Communication Network Management: SNMP OPC Server Basic: 6GK1706-1NW71-3AA0 SNMP Diagnostic of SNMP Supporting devices (SNMP v1) Max. 20 IP-Addresses SNMP OPC Server Extended: 6GK1706-1NX71-3AA0 SNMP Diagnostic of SNMP Supporting devices (SNMP v1) Max. 200 IP-Addresses So depending on the protocol the PC needs to communicate with you need to pickout your IP-Address. All this types are OPC Server although some of the names are maybe a bit confusing. More information about OPC and SIMATIC NET: Successful OPC Foundation Certification for SIMATIC NET OPC Servers
