Before communication is established, it can be necessary to adapt the interface parameters once,
depending on the type of networking.
Network with DHCP server: No adjustment of the factory settings of the interface
parameters of the E-727 is necessary
Network without DHCP server or direct connection (E-727 directly connected to the
Ethernet connection socket of the PC):
−
The start-up behavior of the E-727 for configuring the IP address must be
changed so that the E-727 uses a static address (set IP start to 0).
−
The IP addresses and subnet masks of the E-727 and PC as well as all other
network participants must be adapted to each other (set IP address and IP mask
of E-727 to suitable values).
See “Adaptation of the interface parameters” below for details.
When the IP address is obtained via DHCP server
You should be aware of the following: When a TCP/IP connection is established at which the IP
address is obtained from DHCP server, this address will automatically be written to the
IP Address
parameter (ID 0x11000600) in the volatile memory of the E-727. When you save the current
settings to nonvolatile memory (e.g., with WPA 100) while the current command level is 1, the
obtained IP address will become the new default address of the E-727.
After switching on or rebooting the E-727
The starting procedure of the E-727 must be finished before the communication between the E-
727 and PC can be established. The starting procedure takes about 20 seconds and is finished
when the
Power
LED is continuously lit.
Connection of the network cable when the controller is switched on
Establishing communication via TCP/IP can fail if the network cable was connected to the RJ45
Ethernet socket on the front panel of the E-727 while the E-727 was switched on.
If the establishment of communication fails, switch the E-727 off and back on again while
the network cable is plugged in.
With E-727 firmware version 14.02.01.00 and newer (see response to *IDN?): The network cable
can be connected when the E-727 is switched on. The E-727 will start searching for the DHCP
server in the following cases:
You try to establish communication via TCP/IP in the PC software, e. g., in PIMikroMove or
PITerminal. Note that the E-727 may not be found at the first attempt. Try again after the
first attempt has failed.
E-727 models with EtherCAT interface: The PC interfaces are enabled again after stop of
EtherCAT communication (= the E-727 has left the OPERATIONAL communication state).
Port setting
For communication via TCP/IP, the E-727 only has a single unchangeable port (50000) available,
which cannot be used by more than one connection at a time.
