The file transfer error occurs because the module driver is downloaded with the Ethernet module not recognized by the CP

The Loader command mode is fixed to the TCP/IP communication. UDP/IP communication is not supported.

It is possible as long as the protocol is UDP/IP. In the M_OPEN FB, specify 255.255.255.255 as the IP address to be set

The redundant function of the SPH Series provides redundancy only for the CPU and it cannot make the Ethernet redundant.

The IP address of the Ethernet module will become effective when the power supply is turned off once and then turned on
