AB7670-c switch with AB7670-F

Hello on my network I have: PLC siemens profinet/Anybus Gateway AB7670-C /PLC OMRON ethernet IP.
The gateway AB7670-C is broken and is not possible to buy again .So I have tried with a new version AB7670-F and is not working. The configuration of gateway is correct, But the PLC not see on the project the new station. Is it possible to connect the new model without modify the PLC software? The Company that bild the machine told me no is not possible, the technician Anybus have told me is possible and is working without modify the software but is not like this.

Hello,

If the network requires the MAC address to set up the connection, then you will need to modify the PLC software to detect the new Anybus unit. The way profinet works, just doing a swap is not possible to restore the configuration.

Do you have any additional questions?
