Parameters that can be congured on this screen are:
• SWELL Thr: This corresponds to the threshold value, in %, to detect an overvoltage event.
• SAG Thr: This corresponds to the threshold value, in %, to detect a hole event.
• iNTEr. Thr: This corresponds to the threshold value, in %, to detect a short circuit event.
• SWELL Hys: Hysteresis, in %, over the programmed value in the detection threshold.
• SAG Hys: Hysteresis, in %, over the programmed value in the detection threshold.
• iNTER. Hys: Hysteresis, in %, over the programmed value in the detection threshold.
The value of the hysteresis is always, in part, more restrictive. It is not a
symmetric hysteresis. The detection value is over the programmed value, as a
%. The hysteresis applies in the disconnection or the disappearance of the event.
If the event is for a maximum (over v Thd), the hysteresis will be applied when
the signal drops. If the event is for a minimum (hole Thd and short circuit Thd),
the hysteresis will be applied when the signal increases again.

4.7.3.4. Expansion card parameters
To see the parameters of the expansion card, you have to intro in menu, select cards, and go
to the card to see the parameters.
The picture shows the status of the inputs of the cards or the number of impulses that has
congured each one.
To access the Ethernet and μSD memory card conguration, enter the conguration menu
(menu ---> setup.), and in the EXP.CARD menu, select the position where the card is inserted.
CONFIGURATION
In the Ethernet and μSD memory card conguration screen, it is possible to delete every le
saved to the memory. The data saved is basically separated into two formats as seen in the
gure: quality events with the *.EVQ extension and the standard registries with the *.STD
extension.
A single *.EVQ events le is generated, in which are stores all the quality voltage events. The
*.STD les are automatically generated every day.
60
CVMk2
WARNING: When an μSD card is installed in the system, it is automatically
formatted. It is recommended not to install cards with documents that should
be preserved.
The card format should be FAT 16 and the maximum capacity is 2 Gb.
Neither FAT 32 nor HCSD formats are accepted.
To modify the card conguration parameters, press the EDIT button (F4). Select the option to
be congured and press SET to begin editing.
It is possible to select between yes or no values using the up/down arrow buttons, and the
selection is conrmed with the ok key.
Edit screen options follow:
ESC: Exit the current menu without saving changes.
OK: Save the changes made and exit the edit screen.
Parameters that can be congured on this screen follow:
Delete std: Delete the last day stored in μSD memory (*.STD).
Delete evq: Delete the quality le stored in μSD memory (*.EVQ).
Format: Delete all les stored in μSD memory.
4.7.4.1. Network and communications Protocol
The CVMk2's Ethernet card and μSD memory are specically designed to communicate in
Ethernet networks with Modbus/TCP protocol.
With this system, all the RS-485 communication BUS wiring is extraordinarily optimised, thus
optimising the IT infrastructure already created and facilitating its installation.
4.7.4.2. IP Address Conguration
WARNING: The IP assigned to the CVMk2 with the arp commands is
temporary and the system will recover its original IP when it loses the power
supply. To save the new IP in the system, enter the conguration menu, verify
the modications and exit the menu after saving changes. Accordingly, the
new IP will be saved in the analyzer.
The ARP commands can be used to congure the Ethernet card's IP address.
As for the Windows ARP command, the PC ARP table must have at least one IP address
dened in addition to its own IP address. If the ARP table is empty, the command will return
an error message. From a command window, type in "arp-a", to verify that there is at least one
entry in the ARP table. If the ARP table does not exist or the machine using it is the only one
in the table, ping any other IP address on the network to generate a new entry in the table.
As example if you want to congure the IP address 172.16.14.254 and the MAC address of
the card is 00-20-4A-8D-66-66
CONFIGURATION
61
CVMk2
a) Once that is done, enter the following command to assign the IP address to the
expansion card connection.
c:\ arp -s 172.16.14.254 00-20-4A-8D-66-66
b) Now, execute a telnet to port 1. ( For some versions of Windows the command Telnet
come deactivated). The connection attempt will always fail, but the CVMk2 will change
its IP to the one previously assigned.
c:\ telnet 172.16.14.254 1
c) Finally, execute a telnet to port 9999 and congure all the required parameters. Then,
it is possible to begin conguration of the expansion card's Ethernet converter. It is
very important to save the changes before exiting the conguration menu. Example:
c:\ telnet 172.16.14.254 9999
The conguratios screen is as follow
62
CONFIGURATION
In this menu you can configure all options of CVMk2 ethernet card. Once the desired
conguration exit the application must exit saving changes
The speed set in the conguration menu CVMk2 ethernet port must match the
speed congured on the device itself (see chapter 4.6 Communications). If no
match, the device did not communicate properly with the application or master.
Connection with the master system is made with Ethernet cables consisting of four pairs of
twisted pair wires (screened). The card is connected on one end while the corporate network's
electronics (hub or switch) is connected on the other end.
If a computer or device is directly connected through its Ethernet port, the Ethernet cable wiring
should have a special provision for said communication.
It is also possible to congure the CVMk2's expansion card IP address using Power Studio or
PowerStudio Scada by CIRCUTOR. (Said software can be downloaded from www.circutor.
com).
Once installed, the CVMk2 Ethernet Modbus/TCP device should be selected, as illustrated in
the gure:
CVMk2
You must assign a name and the desired IP address. The IP address must be in the same
address limit than does the computer. This step will fail because they do not nd the device
with the IP that was assigned and display the next screen to request the MAC address of the
card.
You must enter the MAC address of the ethernet card and click accept. The software sends the new IP
address to the expansion card analyzer
4.7.4.3. μSD card conguration
