Siemens "LOGO" 12/24RCEo

Has anyone tried to use AHMI to connect to a Siemens LOGO 12/24RCEo PLC? The s-7 driver will not work so far?

Thanks Larry

Try using ModbusTCP server in Siemens. If you have to transfer something different than integers, you will have to write some code to convert data, depending on the format. It works pretty well.

Thanks for the reply.  I am just testing. I will give the modbusTCP a try tonight.

This is not easy to find the right addressing, I have tried the siemens addressing. Error "Invalid first digit in address"
Tried the AHMI 10001 or 40001. Error "Time out"
Laptop = master  Siemens "LOGO" = slave.  Looking for some example of addressing. I will post if I find the trick.

Got it working.  The Siemens Logo needs to be set as the Server and then the addressing is normal for the AHMI.

Inputs = 00001 - 00024  Outputs = 08193 - 08212
Holding Reg   = 40001- 40592
