Can we have four physical Serial and Four Physical Ethernet Ports in one AC900F Controller?
Client requirement is two have four ethernet interface(IEC 60870-5-104) and four serial( Modbus) interface onboard a controller.
We have proposed Freelance 900F Controller which has 4 Ethernet and 2 Serial interfaces on board, but to get two more serial interfaces can we use the CAN Bus card CI 910F as a serial interface by using any firmware update?

You cannot use the CI 910F. CAN bus uses a completely different physical interface than RS-232 or RS-485. These are not compatible. That means even a different firmware would not help, as it also requires a different hardware interface (transmitter/receiver chip).
