Communication

4.3 TCP/IP Connection

The TCP/IP connection is available on the E-517 front panel of the

controller, via the RJ 45 socket with the network icon. The access differs

depending on the network availability, which can be as follows:

■ Network with DHCP server

■ PC equipped with an Ethernet connection or network without DHCP

server

For the default IP address, IP mask and startup behaviour settings of the

TCP/IP interface see

"Default and Current Settings" (p. 46).

CAUTION

With TCP/IP and USB connections, communication can not be

maintained after the E-517 is power-cycled or rebooted. The

connection must then be closed and reopened.

NOTES

Make sure that your network administrator has not set the network to

forbid unknown devices like the E-517 from logging on.

Only one TCP/IP connection is allowed at any one time: Presently, only

one port (50000) is available at the E-517 so that only one application

at a time can use the TCP/IP connection. The default port setting can

not be changed.

4.3.1 Network with DHCP Server

NOTES

For successful connection, the E-517 startup behaviour for IP address

configuration must be set to "Use DHCP to obtain IP address"

(IPSTART=1; default selection).

You can check the IPSTART settings with the IFS? command

(power-on default setting) and the IFC? command (current setting).

If the IPSTART setting is "Use IP address defined with IPADR"

(IPSTART=0), send

IFS 100 IPSTART 1

The change becomes active with the next power-on or reboot.
