Ethernet Connection
What you will find in this section:
All devices are equipped with an Ethernet interface with an RJ45 socket.
Other communication interfaces can also be available optionally.
- RS-485
- PROFINET
- EtherNet/IP™
Ethernet Connection
All device versions are Ethernet-capable via an RJ45 interface. The devices support 10/100 Mbit full/half duplex. It is recommended to use at least Cat.5 cables (EIA/TIA-568) for installation.
IP addressing
The EMpro devices can be assigned both a static and a dynamic IP configuration.
Current devices support IPv4.
In the delivery state, the devices use a static IP configuration with the following parameters:
|
IP address |
192.168.1.2 |
|
Subnet mask |
255.255.255.0 |
|
Default gateway |
0.0.0.0 |
|
DNS server |
0.0.0.0 |
The entry IP 0.0.0.0, e.g., for the default gateway, indicates that no default gateway has been configured.
When the dynamic IP assignment is used, the device receives its IP configuration via the DHCP protocol from another DHCP server in the same network.
Configuration of the communication interface
You can adapt the following parameters of the network interface:

Mode |
The mode is used to define whether a static IP configuration from the device memory has to be used, or a dynamic configuration should be performed via DHCP instead. |

IP address |
This setting is only used in static mode. Here, the static IP address of the device is configured. In dynamic mode, this parameter is supplied by the DHCP server. |

Subnet mask |
This setting is only used in static mode. Here, the static subnet mask of the device is configured. In dynamic mode, this parameter is supplied by the DHCP server. |

Default gateway |
This setting is only used in static mode. Here, the static IP address of the default gateway to be used is configured. In dynamic mode, this parameter is supplied by the DHCP server. The default gateway is required to allow communication across network boundaries. This is defined by means of the subnet mask. |

DNS server |
This setting is only used in static mode.Here, the static IP address of the DNS server to be used is configured. In dynamic mode, this parameter is supplied by the DHCP server. The DNS server is used to perform name resolutions, e.g., for an NTP time server. |

Device name |
The device supports the NetBios name service. With this protocol, the device can be addressed using a host name, without knowing the IP address of the device. The device has three NetBios names. Two of these names are manufacturer-specific and cannot be modified. You can change the third name. The following names have been defined: First manufacturer-specific NetBios name: <DEVICE_NAME> (e.g., EEM-MA770) Second manufacturer-specific NetBios name: eem<SERIAL_NUMBER> (e.g.,eem1234567890) User-specific NetBios name: <YOUR_DEVICE_NAME> (default: <DEVICE_NAME>) |
