18 Network Communication
This chapter describes how operator panels communicate in a network via TCP/IP
(Transmission Control Protocol/Internet Protocol). TCP/IP is a standardized set of
protocols which enable sharing with other systems and units. The operator panels
can be connected in a network in many different ways, through Ethernet or serially.
Not available for E1012 and E1022.
The operator panel’s built-in Ethernet port can be used for TCP/IP connections.
Connections are made according to Ethernet standards. The expansion module that
is available for E1012 and E1022 can only be used for communication with control-
lers using Ethernet drivers and to load/receive projects; not for network functions.
The operator panel network is a client/server network. Only clients can access data
in the network. Servers only supply data to clients. An operator panel can be both a
client and server at the same time, in order to both supply data and access data from
other operator panels. A maximum of 20 different clients can access data from the
same server. A client can access data from up to 16 different servers.
All operator panels must be assigned an IP address. IP addresses from 192.168.0.0 to
192.168.254.254 are recommended for internal networks.
It is possible to use standardized Internet tools, such as a web browser, an e-mail
server, an FTP client and a VNC client, with the operator panel. A web page can be
created in the PC and downloaded to the operator panel. The web page can contain
real-time data from the controller or the operator panel. Values can be changed, sig-
nals can be set, alarms can be acknowledged etc. through scripts, via Internet, using
a web browser. The operator panel can be accessed and controlled remotely by using
a VNC client.
The operator panel can also send e-mail for special events such as alarm and status
reports.
