Ethernet Settings
LYNX has ethernet (RJ45) as optional hardware feature depending on part number. The ethernet port can be used for the following purposes:
Network Connectivity through Ethernet
Ethernet port is used to connect to cloud (or on-premise server). This is enabled by selecting Ethernet in Network Settings. In this case, there is no need to enable Ethernet under Feature Settings of LYNX.
Ethernet supports dynamic IP (DHCP) and static IP option. By default, dynamic IP is assumed in which IP address is assigned by local LAN router. In this case, there is no further configuration in this section. This is the most common use-case for most of the applications.
TCP/IP (or UDP) Communication with field instrument through Ethernet
Ethernet is used to communicate with PLC/HMI or other machines (using Modbus TCP/IP, SNMP, OPC-UA and other industrial protocols).
For this application, Ethernet/LAN has to be enabled under LYNX Feature settings. Subsequently, applicable TCP/IP based protocol has to enabled and configured.
It is feasible to use Ethernet port for both (1) Network connectivity and (2) Field instrument communication, assuming that instrument is connected to main network.
Enabling Ethernet/LAN under Feature Setting is not required when Ethernet is used only for network connectivity over default DHCP settings.
Updating Ethernet Settings in LYNX
Click on "Read Ethernet Settings" to load present settings. After clicking on "Update Ethernet Settings", the settings will updated.
In case, there are not settings present, a popup "Ethernet Setting Not present" will be alerted. This reflects that default dynamic IP address of TCP/IP being used.
For Static IP settings, select the "Static" radio button and fill the IP address details. Please fill either (a) ALL four entries or (B) ONLY IP address (applicable for peer-to-peer connection).
For dynamic IP, select In "Automatic/DHCP" radio button. With this selection, the custom IP address details are not used by LYNX. So, it is ok to leave them filled.
