Operating Instructions, 03/2021, C79000-G8976-C494-05
Operating modes
You can operate the optical reader in the following modes:
•
DHCP client (via "X1 LAN1" and "X2 LAN2")
• Manual (via "X1 LAN1" and "X2 LAN2")
• DHCP server (when using the "CONNECT" button via "X1 LAN1")
• PROFINET mode (via "X1 LAN1")
These operating modes enable operation of the optical reader:
•
As a direct connection with a PC with or without a DHCP server.
• In a network with several nodes with or without a DHCP server.
• As a PROFINET device in a PROFINET network (via "X1 LAN1").
You can change the network settings in the "Settings > Communication" menu of the WBM
after initial commissioning of the device.
Operating optical readers as DHCP clients ("X1 LAN1"/"X2 LAN2")
In "DHCP" IP mode, the optical reader obtains its network address from a DHCP server. To do
this, specify the Ethernet interfaces to be used as the default gateway in WBM ("Settings >
Communication > Interfaces > Ethernet").
NOTICE
MAC address must be known to DHCP server
Note that, depending on the network structure, the DHCP server must be informed of the
MAC address, the unique device identifier of the optical reader. You can find the MAC
address of the "X1 LAN1" interface on the nameplate of the optical reader, for example. The
MAC address of the "X2 LAN2" interface is +2 higher than the "X1 LAN1" interface.
NOTICE
Ethernet interfaces in different subnets
Note that you must operate the Ethernet interfaces "X1 LAN1" and "X2 LAN2" in two
different subnets. If you do not comply, you cannot save the changes in the WBM, or if you
use SINEC PNI, the IP address of the "X2 LAN2" interface is discarded.
If your network administrator has assigned a DNS name (Domain Name Service) for the
optical reader, you can address the device using its name via the Intranet server.
