Grand contribution Sir, thank you very much!

[@electricalautomation]

Thanks my friend, glad the video could be helpful, Welcome!

[@rangaswamy8604]

Good video in comm. Series.

[@electricalautomation]

Thanks and welcome!

Does the plc s7 1200 comunicate with CompactLogix 5300 need a extend module? I have only 1 plc compactlogix 5300 and 1 plc s7 1200. Thank you

[@electricalautomation]

no need the extra module, please find the detailed step of the implementation in the video.

When I use visual studio 2017 in Twincat 3 then no option available for rename or delete in gvl and dut

[@electricalautomation]

Your software might has problem. Try to use the version >= TwinCAT 3 4024

Hello, how can Client acts as Master and Server acts as a slave. Plz correct it. Client is Slave and Master is server.

[@electricalautomation]

My friend, Client is the role to actively send or receive the data, it is MASTER . Server is role passive, it is SLAVE. Please see the link www.simplymodbus.ca/TCP.htm

Is there a way to transfer string data？

[@electricalautomation]

A string includes 255 bytes (max), so sending bytes

[@xiaochunfeng4073]

So I need to split the string and send it separately? Addition, if I have the Siemens as a Client, which tag type (like 16#00C1) can transmit alphabet ？ Thank you so much in advacne!
