Please note that some recent Ethernet switch and portable PC automatically cross or
uncross their port.
IMPORTANT - Rules for the use of Ethernet ports:
It is recommended to use preferably the port B. This port can handle the
communication with the software OneProd (XPR, CAST, MSC, VIO) and PLC
via Modbus TCP.
If the Modbus devices are on a different network then connect them on port A
When the connection is OK, a green indicator lights on the RJ45 socket (high & right
corner, see on the upper scheme)
You have to reboot the MVX after any change on the network connection
After connecting MVX to an Ethernet network:
- Startup MVX
- Please verify that the light is green on the RJ45 socket. If this indicator
remains off, the network is off or the cable isn’t appropriate.
6.2 IP addressing mode
6.2.1 Default address mode
As default, the two MVX Ethernet ports are « Dynamic IP » configured:
When starting, MVX looks for a DHCP server on the network in order to get an IP
address.
If a DHCP server is present on the network (dynamic IP addresses network),
MVX IP address isn’t known, and the serial number of the MVX is used as
the « hostname ».
If no DHCP server is present on the network, then MVX chooses an IP free
address in the range 169.254.x.y on its B port, right side. In this case use
also MVX serial number as « hostname » to address it.
This addressing mode can be restored using the Reset button: cf. § 8.4
Warning : from V4.1.x .x MVX firmware, A port doesn’t focus automatically to a
default fixed IP address. You shall use B port or you shall setup A port in fied
IP address mode with CAST
