MESR9xxModbus gateways come from the factory with a default static IP address of
192.168.0.1, but will be reconfigured automatically via DHCP as appropriate.
If you need to change the static IP address and do not know what address to use, consult
your network administrator.
Link Status
Link Status of the currently selected Modbus gateway is shown on the Login page of
Vlinx Manager. Link status indicates the type of Ethernet connection between the
computer and Modbus gateway. It will either display 10BaseT or 100BaseTX in full
duplex or half duplex. Link status is dependant on the LAN, switches, hubs used in the
LAN topology.
MAC Address
The MAC Address is a hardware level address of the Modbus gateway that cannot be
changed. It is assigned in the factory. Every Ethernet device manufactured has it own
unique MAC address. The MAC address of each Modbus gateway is printed on the
device's label. The MAC address of the currently selected Modbus gateway is also
displayed on the Login page of Vlinx Manager.
Modbus Priority
This allows the gateway to move high priority messages to the front of the serial message
buffer. The priority can be based on the originating IP address, the Modbus ID, the
Modbus function code, or any combination of the three. Up to five different priorities
can be set.
The default will have all the check boxes unchecked and all the fill in boxes blank.
Modbus Serial Retries
This is the maximum number of times that the Modbus gateway will retry to send a
Modbus message to a Modbus client, before reporting a 0Bh exception if it is selected.
This should be limited to between 0 and 5.
