6.1 Ethernet connection
The interface for the read/write station is compatible with the standards ISO/IEC 61754-24 and IEC 61158. The
device is operated in full-duplex mode with 10 Mbit/s or 100 Mbit/s.
Information!
Only a screened 100 BaseTX cable, twisted pair, Cat 5 or higher, is permitted for use as the
connecting cable. The maximum cable length is 100 m.
It may be necessary to provide additional shielding in conditions with a high level of EMC
interference.
A separate switch may be required for the Ethernet TCP/IP connection.
6.1.1 Ethernet configuration
Using the DIP switch S3, the device can be configured for the following operating modes (see chapter 4.7.3):
With a fixed IP address
As a DHCP client with dynamic IP address
As a DHCP client for a SINUMERIK control system with dynamic IP address based on a fixed station name
(see chapter 4.7.2)
In addition, the following service functions can be set with DIP switch S3:
Reset to default IP address (see chapters 4.7.3 and 6.1.1.1)
Permit or prohibit configuration via a web interface (see chapters 4.7.3 and 7.2)
The individual functions are described below in detail.
6.1.1.1 Fixed IP address and default IP address
Fixed IP address
In this operating mode, communication with the device is via a fixed IP address. In the default setting on
delivery, the factory-set default IP address is 192.168.1.1 and the subnet mask is 255.255.255.0.
Information!
This operating mode is not suitable for operation in conjunction with a DHCP server.
The DIP switches S3.3 and S3.4 always remain OFF in this operating mode (see DIP switch settings
in chapter 4.7.3).
On powering up the device, the fixed IP address last set is always active after the application of the
power supply in this operating mode.
You can assign an individual, fixed IP address via the web interface of the device (see chapter 7.2). To do this,
access via a web browser must be enabled (see DIP switch settings in chapter 4.7.3).
Default IP address
Each device has the factory-set default IP address 192.168.1.1 and the subnet mask 255.255.255.0.
Information!
If you have forgotten your self-defined IP address, you can reset the device to the default address
again. The self-defined address is then overwritten by the default address.
For this purpose proceed as follows. The device can be connected to the network or disconnected from the
network during this routine.
1. Disconnect the device from the power supply.
2. Set DIP switch S3.3 (see DIP switch settings in chapter 4.7.3) to ON.
3. Apply power supply. Wait until the device has adopted the default IP address. This situation is indicated by
the LED flashing red/green.
4. Disconnect the device from the power supply. Set DIP switch S3.3 to OFF (see DIP switch settings in
chapter 4.7.3).
