ioLogik Cellular Micro RTU Controller Utility: ioAdmin
server also relates to the node created in the Active OPC Server.
LAN Settings Panel
The LAN Settings panel is available after you log in as administrator. You will be able to configure IP settings,
Modbus/TCP Alive Check Timeout settings, DNS settings, and SNMP settings.
IP Settings
You can set up a static or dynamic IP address for the ioLogik, as well as the subnet mask and gateway address.
Click Accessible IP if you wish to allow only certain IP addresses to have network access to the ioLogik and
attached sensors. Access will be granted only to the IP addresses that you list in the Accessible IP screen. Any
requests from sources that are not on the accessible IP list will be unable to use Modbus/TCP or ioAdmin to
access the ioLogik.
Modbus/TCP Alive Check Timeout Settings
The Modbus/TCP Alive Check Timeout is designed to avoid TCP connection failure. If the network host is unable
to respond due to hardware failure or a network problem, the ioLogik will continue to wait for a response from
the host. This will cause the TCP port to be occupied indefinitely by the host. On the other hand if Modbus/TCP
idle connection timeout interval is enabled, when the ioLogik’s connection to the server exceeds a specified time period
the device will automatically release its modbus/TCP connection to the server to free up the port for the next connection.
