IP address has been changed, the device will not be able to communicate with the Modbus gateway. Therefore, disabling DHCP and using a static IP address is recommended. Page 22 Vlinx MESR9xx Modbus Gateway Manual Documentation Number MESR9xx-4508m www.bb-elec.com/... -
Page 27: Firmware Version
If DHCP is not selected you must type in a static IP address when configuring Network settings (on the Vlinx Manager Network page). The static IP address remains the same each time the server is powered up or starts/restarts.
