Hello All,

I have couple of PLCs connected to the switch.

I want to add AccessPoint and be able to connect to the PLCs through wireless lan.

The current situation is:

- when my PG/PC is set to <network.card>.TCPIP.Auto i am able to go online in FB/FC,

- when my PG/PC is set to <network.card>.ISO i am NOT able to go online in FB/FC, moreover i am NOT able to search station through network (for instance, when i am choose from top Simatic Manager menu: PLC -> Upload station to PG, Simatic is not able to search  any PLCs).

What i am missing?

Hello SuHu,

do you connect PLC behind a WLAN-Client?

With TCP, you address the partner over IP address.
ISO (I think) is Layer 2 with MAC address.

If you want to reach the PLC behind the client with MAC, you have to configure a Layer2Tunnel in WLAN-Client. Otherwise, the Access Point only knows the MAC of the WLAN-Client.

Have a look in Chapter 4.6 of this manual

Hello

the Protocol that is used for this is called DCP. You need a router or Access Point that can handle a DCP Forwarding.
