Installation of Ethernet devices
6.4.1 Connection
Before devices can be connected to an existing Ethernet network, you have to ensure that they
will not disturb the normal network service. The rule is:
None of the devices to connect is allowed to have the same IP address
than another device already installed
The factory setting of the IP address of A
PLUS
is: 192.168.1.101
The standard RJ45 connector serves for direct connecting an Ethernet cable. If the PC is directly
connected to the device a cross-wired cable must be used.
The network installation of the devices is done by means of the CB-Manager software (see
6.4.2
) or
directly via the local programming on the display. As soon as all devices have a unique network address
they may be accessed by means of a suitable Modbus master client.
Interface:
RJ45 connector, Ethernet 100BaseTX
Mode:
10/100 MBit/s, full / half duplex, Auto-negotiation
Protocols:
Modbus/TCP, NTP
Function of the LED's
LED 1 (Green)
ON as soon as a network connection exists
Flashing when data is transmitted via Ethernet connection
LED 2 (Orange)
Flashing with 4 Hz during start-up
ON during Modbus/TCP communication with the device
To have a unique identification of Ethernet
devices in a network, to each connection a
unique MAC address is assigned. This
address is given on the nameplate, in the
example 00-12-34-AE-00-01.
Compared to the IP address, which may be
modified by the user any time, the MAC
address is statically.
