17-8 Comparison with Previous Models
Note Limited by the CP1W-CIF41 inner bus protocol (Host Link, 7,2,E, 115200 bps), the system response perfor-
mance is longer than the existing Ethernet Unit. Please consider the FINS command processing time and
buffer limitation when using the CP1W-CIF41 Ethernet Option Board.
