I exactly want to communicate my CPU 315-2 PN/DP with RF660R reader. I have downloaded the program that has been published at Siemens Automatin web site. There is a VAT table and I have to change some settings that has to be appropiate with my system. Reader and the CPU communicate over TCP/IP with Profinet. These are:
1. IP address of the Reader (eg. 192.168.3.251)
2. Port of the reader (eg.10001)
And there is a local port variable in the VAT table. I think it is the CPU's port. So I think that it has to be changed.
Thats all

I have not used RF660R, but after looking thru the program this iswhat I understand. It uses open TCP communication to PLC. The program uses internally TCON to establish the connection. So the parameters you enter in DB300 are usedas the connecton parameters.

So you need toenter IP address of the RF660 at DB300. DBW 148 to 151

Since you have 192.168.3.251 it will be

rem_start_adr = B#16#FB,

B#16#03

B#16#A8

B#16#C0

And for remoteport # 10001 (this should be same as the port # you configured in RF660)

rem_tsap_id =B#16#11

B#16#27

The local port # is set at

local_tsap_id= B#16#22

B#16#4E

This value 4E22 (hex)= 20002

This is the port number used by TCON in TCP connection. This is not a HW port number. This is a virtual port # used by the connection. So this number is not configured anywhere in HW config.If you have multiple RF660, then each FB300 called for a RF660 will need aunique numberas local_tsap_id.

But for any reason (which I do not understand yet) if you want to change the local port#, all you need to do us change "local_tsap_id".

If you need to lean more about open TCP connection, you can read chapter 23 in the manual given below.
