Hello

I would like use S7 300 + CP343-1 Lean and Zebra printer (TCP/IP). I am beginner. I work in TIA portal. Do you have any documents (example) for TCP/IP communication between PLC 300 and other device in TIA portal?

THX

--------------
Split from TIA V13: Ethernet Communication between S7-300+CP343-1Lean and S7-1200.

Hello,

there is no special Application available. To realize that communication just use the following example, change IP adress and port to your networkconfiguration and define your commands byte for byte as hex-code of ASCII-sign  in sending Datablock!

How di you program the communication blocks FC5 and FC6?

Just migrate that projekt to TIA..

Hello bartosm,

there is a Wizard available for TCP/IP communications:

Wizard for creating connection data for open TCP/IP communication (Open Communication Wizard)

Also check these FAQ:

In the case of open TCP/IP communication via Industrial Ethernet using T blocks with IE CPs and CPUs, why are different amounts of messages sent when the maximum length of 1452 bytes of user data is transferred?

Hello, i have the same problem, but im trying communicate a TELESIS marker  with a CPU 315 2 PN DP with out a CP, somebody  know how use a oc wizard  with other device, the manual of the wizar only has the step to cummunicat others PLCs. 

Regards

 to the first question: 

you need to use the CP? You can also use the intern ethernet interface of the PLC and use open user communication (T-blocks). These blocks are more variable than the AG_SEND, ... blocks.

 there is an online help in STEP 7. You can also use this one and you do not have to use the wizard.
Last time I used the wizard I think you can use the connection to an PLC for other devices, too... but at this point I am not really sure.
