IP address assignment

The EP6601-0002 can assign IP addresses to connected devices and works as a DHCP or BootP server for one device. The settings for this must be made in the System Manager (EP6601-0002 --> Advanced Settings --> Mailbox --> EoE) as follows:

• Default setting "Switch Port".
  The EP6601-0002 works like a normal switch and transparently forwards Ethernet frames to TwinCAT/Windows.
  
• Setting "IP Port".
  The EP6601-0002 works with address assignment to one connected Ethernet device. Enable a DHCP or BootP client in the Ethernet device (see Network adapter settings in the operating system). The EP6601-0002 responds to the DHCP or BootP request from the Ethernet device by assigning the specified IP address/subnet mask to the Ethernet device. In the DHCP procedure, this address is regularly requested again by the client and assigned by the DHCP/BootP server (EP6601-0002).
  

Please note:

• do not use the "DHCP" checkbox - the checkbox "IP Address" enables the DHCP/BootP function in the EP6601-0002.
• the gateway, mask and server settings are also communicated to the client/device.
• only one address can be assigned, i.e. no switch with connected Subscribers may follow.
• the address range must match that of the EtherCAT adapter.
• DHCP server identifier: some DHCP servers require a ServerID in the answer telegram.
  Solution for EP6601-0002: The value 0x1000 must be entered in CoE 0xF800:01. If a default gateway is entered in the EP6601-0002, this is then used as the DHCP server identifier.
