(2) Connection of MC protocol devices
The message format of SLMP is the same as that of the QnA compatible 3E or 4E frame format of the MC
protocol. Therefore, external devices that support the MC protocol can be connected to CC-Link IE Field Network.
(3) Communications using the specified IP address over CC-Link IE Field Network
(IP packet transfer function) ( Page 105, Section 7.3)
With this function, communications using the specified IP address can be performed over CC-Link IE Field
Network. For example, a personal computer can communicate with the FTP server. Two networks of CC-Link IE
Field Network and Ethernet are not required, resulting in reduced wiring cost.
The IP packet transfer function allows an IP packet to be transferred from an external device to a request destination. An
Ethernet adapter module cannot be used as a request source or a request destination.
