ESERV-M12T
(Rev. 1210)
By filling in the drop down menu of ports with slave devices attached, adding IP addresses of slaves, up to 10
address ranges can be routed.
By default all boxes are unchecked, the drop down menu is set to serial port one, and all fill in boxes are blank.
IP ADDRESS
Software or hardware attempting to access the Modbus gateway via the network must know the
IP Address
of the
server. If DHCP is selected, the Modbus gateway requests and receives a dynamic IP address from a DHCP server
when it first connects to the network. If DHCP is not selected you must type in a static IP address when configuring
Network settings (on the Modbus Gateway Manager Network page). The static IP address remains the same each
time the server is powered up or starts/restarts.
ESERV-M12T Modbus gateways come from the factory preset to receive an IP assignment from a DHCP Server. If a
DHCP Server is not available on your network, it will default to 169.254.102.39. 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 the Ethernet Modbus
Gateway 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 dependent 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 its 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 the Ethernet Modbus Gateway 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.
