After the application of the power supply, the device now powers up again with the default IP address. A new,
fixed, self-defined IP address can now be set again using the web interface (see above).
Information!
With the modular interface adapter, the RESET button on the front can be used to disconnect the power
supply and restart the device.
6.1.1.2 Dynamic IP address
In this operating mode, the device is a DHCP client. The IP address is assigned by a DHCP server (see DIP
switch settings in chapter 4.7.3).
Information!
This operating mode is unsuitable for operation in a network with fixed IP addresses.
6.1.1.3 Operation in the Siemens system network
The Siemens system architecture is designed so that the HMI PRO (Human Machine Interface) software and
the operating system run on one or more NCU (Numeric Control Units)/IPC (Industrial PCs). The TCP/IP
protocol is used for communication.
The EKS communicates with an NCU. Linux is used here as the operating system in the NCU. Simple TCUs
(Thin Client Units) with MCPs (Machine Control Panels) are provided at the control station for operation and
visualization. A control station typically consists of a TCU and MCP. Communication between TCU, MCP and
NCU takes place completely via Ethernet.
The EKS communicates with an IPC. Windows
®
is used as the operating system here. If the EKS is to be
operated remotely from the IPC, the EKS with Ethernet interface can be used.
Each station in a system network is assigned an unambiguous SINUMERIK station name. The EKS can be
integrated into this network. According to the principle of flexible assignment of stations to each other, it is
possible to define which stations are to work together, i.e. which TCU is to access which NCU/IPC with which
MCP. This means that an EKS can be assigned to a specific control station.
A DHCP server runs on the NCU/IPC, and a DHCP client runs on the connected network stations. With this
SINUMERIK DHCP address assignment routine, an unambiguous SINUMERIK station name is made up of an
assigned device name and a number. In the case of the EKS, this station name consists of the identifier EKS
and a consecutive number between 001 and 254 (around 1 byte). The numbers 000 and 255 are not supported
by the SINUMERIK address assignment routine. The station name for a specific EKS would then be EKS027,
for example. No programming device or PC is required for setup within the Siemens network. When carrying out
setup, it must be ensured that each device receives a separate number in a network. An unambiguous IP
address is then dynamically assigned to this name via DHCP. DNS is used to ensure that each device can be
addressed by its name.
The EKS can obtain the IP address corresponding to the SINUMERIK DHCP address assignment routine.
Activation of the SINUMERIK address assignment routine must be set by means of the DIP switch S3 (see
chapter 4.7.3). The 3-digit numbering as part of the station name (i.e. 027 in the example above) can be set by
means of the DIP switch S2 (see chapter 4.7.2).
System integration in the user software is performed by Siemens.
