Product description
1.1 Function
The VEGACOM 558 interface converter is
used for conversion of VEGA-specific
protocols of the DISBUS and LOGBUS into
the TCP/IP protocol. It enables the connection
of VEGA signal conditioning instruments
VEGAMET series 500 and 600 and the
VEGALOG 571 processing system, and
through this, the connection of VEGA transmitters to an Ethernet network. When connecting signal conditioning instruments, the
data of the VEGA protocol "DISBUS" are
used, with the processing system, the VEGA
protocol "LOGBUS" is used.
VEGACOM can be used as a web server,
making the measured values of the connected VEGA instruments available in html
format on the Ethernet. At the office level, the
measured values of VEGA instruments can
be displayed with an internet browser on
each computer connected to the network.
The data of VEGACOM 558 can also be
called up via the WWW. Furthermore, it is
possible to send emails containing measured
values at predefined times and dates. For
integration in process control or visualisation
systems, VEGACOM 558 provides a
Modbus / TCP server.
Network participants provided with the adjustment software VVO (VEGA Visual Operating) (e.g. service technicians) can adjust the
VEGA instruments via Ethernet. With the
visualisation software VV (Visual VEGA), it is
also possible to access via network connection VEGACOM 558 and thus the measured
values of the VEGA instruments.
Note:
To enable VEGALOG to work together with
VEGACOM 558, the CPU card of VEGALOG
must be equipped with the software version
1.30 or higher.

4.2 Adjustment software
There are two ways to adjust VEGACOM 558
with the adjustment software VVO, either via
the RS232 interface or via the Ethernet interface. In both cases, VVO version 2.80 or
higher is necessary.
For settings on VEGACOM 558 relating to
certain internet services (e.g. web server,
Mail-Client, etc.), an internet browser, e.g.
Internet Explorer or Netscape Communicator,
must be used instead of VVO. Adjustment
with an Internet browser, however, requires
that VEGACOM 558 and the PC be connected via a network (Ethernet).

5 Configuration of VEGACOM 558
The configuration of the instrument is done with the adjustment software
VVO (VEGA Visual Operating), version 2.8 or higher, and can be realised via the standard serial interface or Ethernet connection. Connect
VEGACOM 558 to the PC (as described in chapter "4.1 Ways to connect"). Start VVO and choose Planning.
Enter in each of the following fields (name and password) vega and
then choose mode Direct cable connection.
12 VEGACOM 558 Ethernet
Configuration of VEGACOM 558
If necessary, confirm the following message (if VEGALOG or VEGAMET
was already previously connected to VVO, another message appears)
and wait until data transmission is finished.
VVO now shows the connected instrument, in this case a VEGALOG with
a VEGACOM 558 which is connected via the standard serial interface to
the PC. Click to Configuration and to Measuring system.
VEGACOM 558 Ethernet 13
Configuration of VEGACOM 558
Click in the following window to VEGACOM 558 and then the button
Configuration (VEGACOM can, however, be located in other positions
than shown here).
The following image shows the configuration window of VEGACOM 558.
By clicking different registers, all parameters of VEGACOM 558 can be
reached.
14 VEGACOM 558 Ethernet
Configuration of VEGACOM 558
5.1 Adjust communication mode with VV O
During installation, VVO is set to "serial communication" (standard). For
access via Ethernet to VEGACOM, VVO must be switched over. Click in
the VVO main window to Configuration > Program > Communication.
Choose in the window "Communication" TCP/IP. VVO searches the network for existing VEGACOMs and enters the result (IP addresses) in
the list box. Then the requested VEGACOM can be selected out of the
list. If it is not found by VVO (because it is probably switched off or not
already connected), the IP address must be entered manually. After
confirmation with OK, VVO searches the network and makes a connec-
tion to the instrument.
If a connection to a VEGACOM 558 (whose IP address has already
been entered) should be made at a later time, you only have to select it
from the list.
VEGACOM 558 Ethernet 15
Configuration of VEGACOM 558
5.2 IP address
If the instrument is to be connected to the network, it must have an IP
address for identification on the net. As default, VEGACOM 558 has IP
address 192.168.200.200.
Generally, the system administrator assigns a unique IP address for
each network participant. To assign this address on VEGACOM 558,
move to the configuration window of VEGACOM (here it doesn’t matter if
a serial or a network connection exists). There you click the register
Ethernet Port. In the fields, you enter the IP address and a host name,
if necessary also the subnet mask and DNS server addresses. Make
sure that the host name does not contain special or blank characters.
The baud rate can remain at Autodetect. Then you have to Save. With
Quit (push twice) you return to the VVO main window.

5.3 Connection via modem
If VEGACOM 558 is to be adjusted via modem, you have to adjust the
mode Modem (as shown in the following three images).
VEGACOM 558 Ethernet 17
Configuration of VEGACOM 558
For modem operation, also note the settings in the configuration window
of VEGACOM. As default, the modem initialisation is switched on and the
baud rate is set to 9600. These settings relate to the local modem.
For detailed information on modem operation, see operating instructions
"Remote parameter adjustment".

5.4 VEGACOM 558 on DISBUS
If VEGACOM 558 is operated in conjunction with VEGA signal conditioning instruments (e.g. VEGAMET 515, VEGAMET 614), it is a participant
on the DISBUS. Max. 15 VEGAMETs can be connected to the DISBUS,
in addition, two participants can be a VEGACOM 558.

Configuration of VEGACOM 558
5.5 Real time clock
Since VEGACOM 558 can send time-controlled emails, the current time
must be available. In the CPU card of VEGALOG 571 there is a batterybuffered real time clock which is used by VEGACOM. In the illustrated
configuration window, you can set time and date manually or they can
be transferred with the button PC system time from the PC to the RAM
memory of the CPU card.
With Save, the time is permanently saved and and remains even in case
of mains failure.
Note:
If VEGACOM 558 is used in conjunction with DISBUS, no buffered real
time clock is available. After a supply interruption to VEGACOM, the time
must be readjusted.

Configuration of VEGACOM 558
5.6 Activate password protection
To avoid unauthorised access to VEGACOM 558 and the connected
processing systems VEGALOG or VEGAMET, they can be protected
by a password. Especially when VEGACOM is adjusted via network
and is therefore accessible to each network participant, it can be important to preclude unauthorised adjustment. Click to Configuration >
Measuring system, in the window "Configuration Measuring system"
you click to the VEGACOM 558 and then to Access protection.
VEGACOM 558 Ethernet 21
Configuration of VEGACOM 558
In the following window, you have to choose Activated and enter a
password for access with VVO as well as with VV (adjustment software
Visual VEGA). Then Save the setting.
However, the access protection is not yet activated, and only with the
next VVO start (and with switch-over of the communication mode from
standard to network and vice versa) will you be asked to enter the
password.

6 VEGACOM 558 as Modbus / TCP server
VEGACOM 558 collects measured values of
the VEGAMET 513, 514, 515 and 614 signal
conditioning instruments (via DISBUS) or
VEGALOG 571 (via LOGBUS) and stores
them temporarily for collection via MODBUS /
TCP.
The way the measured values are stored in
the temporary storage of VEGACOM 558 for
the higher-priority processing system depends on the selected configuration. It depends on whether VEGACOM 558 is
connected to DISBUS or LOGBUS.
VEGACOM 558 follows the "Open MODBUS /
TCP Specification" release 1.0 from Schneider Electric. This standard is supported by
many process control systems, remote IO’s,
visualisation programs and OPC servers.
Note:
When connecting to DISBUS, the storage of
measured values can be determined additionally via the HTML configuration page
"General".
Beside the measured values, it is also possible to call up the status of the contact inputs
and outputs via VEGACOM 558.
Call up of the measured values via:
- Function code 04 (= Read Input Registers)
6.1 Storage of measured values when connected to DISBUS
The addressing of the measured values for
Modbus systems is "word-oriented". In
VEGACOM 558, a measured value is represented by two words, the first word includes
the real measured value, the next higher
word the associated status information. In the
standard, the term "register word” is also
used instead of the term "word”. The addressing is done via existing library calls of
the process control system (e.g. Modicon).
As already mentioned, the storage of measured values for VEGAMET signal conditioning
instruments can be influenced by the user.
For this purpose, a connection to VEGACOM
558 must first be provided via a web
browser. By activating the entry "DCS 1-7
from MET 1, …" in the section "storage of
measured values for MODBUS / TCP” in the
HTML page "General", the measured values
are saved in rising sequence acc. to the
VEGAMET addresses.
