Hi, read the comments, my question is how many TCP connections can the S7-1200 make? I need 45 IPs in Modbus TCP/IP, thanks. ------------------------------------------------------------------------------------------ |

Hi, S7-1200 can 8 to maximum 12 connections (OUC). Check this: With which devices can the S7-1200 communicate via the integrated PROFINET interface and which protocols does the S7-1200 support?
Regards, Towome |

Hello. The solution to your problem is to use 'dynamic' connections. Defining a TCP connection in the hardware configuration makes the connection a fixed connection. When the communication instructions define the connection (IP address and so on), then the connection becomes dynamic. A dynamic connection has the ability to be redefined.. There is a limit of how many connections can be open at any one time (as mentioned by Mr. Towome). But you can cycle through all the 40 devices within a time-span. Study what you can use from the helpful communication library: ~ |
