Siemens S7 1200 Modbus TCP communication with Windows client

Do I need to buy a Modbus TCP license or it is included with TIA Portal V14?

Hi ,

I pull all input, output and analog signal in 1 DB for server , so my client read still need create different register ? Example read output from server ip is 10001 , then another block for client just 40001 ? It this possible create all combine dB by using 1 dB ?
Please advise

hi,
Can S7 1200 use Modbus TCP and Modbus RTU simultaneously?

Thank u. Now, what do I have to do for communicate with several TCP slaves.
If I change the address (MB_DATA_ADDRESS) while PLC is running, the module holds the communication only with the initially configured slave. I mean, the module only communicates with the originally configured device.

hi. I'm using Tia portal V14. The master Modbus block in my software dont have parameter "connect" as yours. Whether the library was wrong? Thank

Hi do you know what it may cause error 80C5 in status ? I follow your video and change ip adress in modbusclient but i don't know what is happening, for now i am just using S7-PLCSIM for simulating my program, is it necessary to use the physical plc?

Nice video, where can i get this nice Modbus slave program?

Nice video, how about Communication PLC to DCS, can we use moodbus as protocol ?

The firewall of my private network has blocking the communication, but i can connect the modbus poll and modscan with the modbus tool when my firewall is on, but not my plc, thx for the video!

Awesome

thanks a lot for the well illustrated and explained video, really appreciated. what is the name of the modbus tool i need to download it

I had to stop/start the CPU, works great, thank you.

Hello and thanks for your helpful video.
When I click on the link for the tool, it doesn't lead to a link for downloading or buying the software. Is there any other link you can share here to download? Thanks a lot.
