14.6 Communication Functions
Ethernet Communications
Connection: Ethernet (10BASE-T)
Protocol: TCP/IP
E-mail transmission function:
Recipient addresses: 2 address groups (multiple addresses
can be specified using up to 150
characters for each group)
Notification types: Notifies the following information through
e-mail. Select notify or not notify for
each address group.
Alarm notification, appointed hour
notification, and report notification
Web server function: Displays screen images, alarm information, instantaneous
values, and other information on a browser application
(Microsoft Internet Explorer 5.0)
FTP client function: Automatically transfers data files from the CX2000 to a server
FTP server function: File transfer and directory operation and file deletion on the
external storage medium from a request by a PC on the
network
Real-time monitor function:
Real-time monitoring of CX2000 measured/computed data is
possible using a dedicated protocol
Serial Communications
Used for ladder communications, Green series communications, and Modbus
communications
Connection: EIA RS-232(CX2 0- -1- )
EIA RS-422/485(CX2
0- -2- )
Protocol: Dedicated protocol or Modbus protocol
