Communication
function
General purpose
communication mode
This function performs commun ication between controll er unit and other node by
using TCP/IP or UDP/IP protocol. It is possible to commun icate with all kinds of node
duetofreedataformat.
Fixed buffer
communication mode
This function performs communication by using the fixed buffer that Mitsuibishi PLC
provides.
Loader command
communication mode
This function sends/receives dedicated loader commands between MICREX-SX
series devices.
FTP server mode Controll er u nit becomes FTP server.
FTP client m ode Con troller unit accesses FTP server as a FTP client by using a dedicated FB.
SNTP client mode Controller unit obtains the current time from NTP server on the network.
Mail fun ction This function performs sending e-mail . (Note1)
Access method CSMA/CD
Transmission protocol TCP/IP, UDP/IP, ICMP, ARP
Max. n umber of simultaneous
communication nodes
(num ber of comm unication ports)
10 stations (ports)/module
Note: The number of communication ports that can simultaneously be opened for one
resource is 56. When other commun ication module exists, be careful that the
number of opened ports per CPU doesn 't exceed 56.
Transmission code Binary/AS CII code
