VEA 3CGi
1. General
Installed to 35mm DIN- RAIL
Steel plate case
Powered from the VAMP relay via serial cable (from the
LOCAL port of the relay) or from an external power supply
interface. There is a screw terminal (6 , see figure 1) for
connecting an external power supply.

2. Ethernet port : 10 Mb/s, RJ-45 connector
3. 4 LED indicators:
Power: Powered by VAMP relay
Error: Internal error
A/B Future feature
4. Act: Communication active
5. Link: Ethernet link is active
6. External power supply and grounding interface:
Range: +12..24Vdc
Power:1W
Connection: Removable terminal block
Grounding help limit the effects of noise due to
electromagnetic interference (EMI) Run the ground
connection from the right most connector of the 3-
contact terminal block to the grounding surface prior to
connecting devices.

1.2. Application
Figure 1.2-1 Application
VAMPSET data over Ethernet
Read / write of relay settings
Upload of disturbance recordings
Time synchronization of relays with NTP-server
NTP time server connects to Ethernet
NTP server gets its time from GPS or Internet
VEA 3CGi gets synchronized via the server, using SNTP
The relay is synchronized to VEA 3CGi via the Local
interface
Modbus TCP over Ethernet
Read / write of relay data in Modbus registers
The applicable Modbus register numbers for each VAMP
relay type can be found from documents called “ Modbus
parameters”.
The same data which is available via serial Modbus RTU
protocol is also available via Modbus TCP.

1.3. Operation
Figure 1.3-1 VEA 3CGi operation principle
Function
Open the communication tunnel between Port 23 / Telnet
and Local port, which enables the VAMPSET connection to
VAMP relay.
Open the communication tunnel between Port 502 and
Remote port, which enables the use of Remote port
protocols, e.g. Modbus TCP.
Initialization
After resetting, the VEA 3CGi performs the following the
initialization sequence:
1Opening the Local port and configuration to speed 38400
b/s.
2Obtaining the necessary setting from the relay through the
Local port.
3IP setting in accordance with the information obtained from
the relay.
4Opening and configurating of the Remote port according to
the information obtained from the relay.
5Initialization of communication through Port 23 and 502.
6Initialization of NTP query if IP address of the NTP server
has been obtained from the relay.

3. Configuration
3.1. The Ethernet settings of the relay
Connect cable VX003 to relay’s front panel (see Figure 3.1-1).
Find the Ethernet-menu of the relay with VAMPSET and give
proper values to parameters " IP Address " and " NetMask".
The other parameters can be left to their default values when
testing the communication.
To learn about possible IP addresses you may have to talk with
the system administrator responsible of the Ethernet network
you are going to use for communications. A fixed IP address
must be used because DHCP is not supported in VEA 3CGi.

3.2. VEA 3CGi to the relay and Ethernet
network
Connect VEA 3CGi to a 200-series relay’s LOCAL serial port
with cable VX003 . Connect the VEA 3CGi and the PC to an
Ethernet Switch (see Figure 3.2-1 ). Connection to 100-series
relays is done with VX015 cable and connection to VAMP 40 is
done with VX030 cable.
