For S7-300 you can have a look at the article "How can you establish OPEN MODBUS / TCP communication from a SIMATIC S7 and where can you find further information?":http://support.automation.siemens.com/WW/view/de/22660304. |

Hello Asa Juan; To complete Alex's reply, you will ind information on the S7-1200 interface for Modbus TCP in chapter 12 of the following manual: SIMATIC S7 S7-1200 Programmable controller Modbus TCP communication Modbus TCP (Transmission Control Protocol) is a standard network communication protocol that uses the PROFINET connector on the CPU for TCP/IP communication. No additional communication hardware module is required. Modbus TCP instructions in your program · MB_CLIENT: Make client-server TCP connection, send command message, receiveresponse, and control the disconnection from the server · MB_SERVER: Connect to a Modbus TCP client upon request, receive Modbus message, and send response Hope this helps, Daniel Chartier |
