Online connection over the Internet (eg VPN connections)

ConnectionPN

Sample configuration for a VPN dial-up router that is connected to a Siemens CPU S7-315PN.

The configuration must be adapted to the local connection.

Possible problems with online connections

  • The response time of the controller is too slow. Measure: Increase the timeout (eg to 5000000)
  • The PLC can not be reached via Ping. This is the case when the ping response is deactivated during the VPN connection. Result: The “Find connection” function is not connected. All parameters must therefore be entered manually and tested using the “Check connection” function.

Online connection via network card (eg CP 343-1 Lean)

ConnectionCP

Sample configuration for a Siemens CP 343-1 Lean.

This configuration should apply to all S7-300 and S7-300 CPs with Ethernet connection.

Note: If you have problems, try setting the CPU slot to 2.

Online connection with NetLinkPro via MPI or Profibus (eg S7-315-2DP)

Connection DP

Using the NetLinkPro adapter from Deltalogic.

If the adapter is connected to the Profibus port, the protocol “DP protocol with NetLinkPro (Siemens S7-300 / 400)” must be set. The remaining settings are valid for the Profibus. For example, the Profibus address of the PLC must be entered at “MPI address PLC”.

Sample configuration for a Siemens CPU S7-315-2DP.

This configuration should apply to all S7-300 and S7-400 CPUs with MPI or Profibus connection.

Online connection via Profinet (eg S7-315PN)

ConnectionPN

Sample configuration for a Siemens CPU S7-315PN.

This configuration should apply to all S7-300 and S7-400 CPUs with Profinet connection.
