Improved FINS Message Communications from CP1W-CIF41
The following functions have been maintained according to the existing Ether-
net Unit models for CP1W-CIF41.
• The maximum number of nodes is 254.
• Communications are enabled even if the host computer's IP address is
dynamic.
• An automatic client FINS node address allocation function makes it possi-
ble to connect online to the PLC even if no FINS node address has been
set for the host computer.
• FINS message communications are enabled in both UDP/IP and TCP/IP,
and it is enabled in TCP/IP with up to 3 simultaneous connections.
→
Previously CP1W-CIF41 is enabled in TCP/IP with up to 2 simultaneous
connections and all can only be set to server.
• Multiple FINS applications, such as the CX-Programmer, on the same
computer can be connected online to the PLC via Ethernet.
