Hello! Does anybody know how to establish data connection between PC (WinСС) and remote control PC via TCP/IP? we have to send HMI data from the Boiler's redundant OS servers to the remote control PC. Please, see the attachments.

HiRollex Do the servers and the remote control PC have WinCC installed?

Hi Rollex, I havent heard of Modbus TCP/IP communication between two PCs. You can use the OPC communication to transfer data from wincc server to Normal PC. See below link to know more about OPC communication: https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=22892718&caller=view |

OPC would be an obvious choice if possible for your needs, just adding the remark that Modbus TCP/IP also can work between 2 PC's if one can be set as Master and the other as Slave (prefered with fixed IP). Depending on how much data you want to transfer, is sending csv-files over 3G an option? |

This is very much possible using Modbus TCP since WinCC supports Modbus TCP channel. See attached extract from the WinCC Communications Manual. Modbus TCP is a very robust and fast communication protocol over long distances! AttachmentCommunication.pdf.pdf (245 Downloads) |
