It does not seem that the files are still available when you follow the link. Does anyone have another link? I am also looking for both the Client and server Modbus TCP for the S7-1200. I looked at the one by Siemens (CE-x22) but it was only designed to communicate via function code 3, 40001 registers. I need to poll 10001 and 30001 registers as well. Any help would be appreciated. |

Do you want to read from the PLC or write to the PLC from another device? |

An alternate approach could be to use a modbus RTU to modbus TCP convertor. I have used the XPress DR-IAP in the past and it has worked well. It just converts modbus RTU protocol to modbus TCP protocol, so it can be client or server depending if you use master or slave RTU. |
