Instrument Description
Hardware
The DataVU7 recorder has a modular
design. The basic form consists of a
PSU board (incl. relays) and a CPU
board (incl. Ethernet, RS232/RS485,
RS232 for barcode reader and USB)
Module slots 1, 2 and 3 can be fitted
with the following options, 6 analog
inputs, 3 analog inputs & 8 binary
inputs/outputs or slot 3 can be fitted
with a module with 6 relays.
As an option, the PSU board can be
equipped with PROFIBUS-DP
communications.
Data recording
Measurements are logged
continuously with a 125 ms sampling
cycle, where reports are compiled
and limits checked.
Measurements are transferred to the
main memory of the instrument,
according to the programmed cycle
time and stored value (max, min,
average, min & max, instantaneous
value or economy mode).
The recorder saves the data in
groups, and an input can be
assigned to several groups to a
maximum of 9.
Main memory (SRAM)
The data stored in the SRAM are
regularly copied to the internal
memory in 20 kbyte blocks.
Internal memory
When a block in the main memory
has been filled, it is written to the
internal memory with a capacity of
256 Mbytes.
Every write action is monitored, to
immediately identify any errors in
saving the data.
The instrument monitors the capacity
of the internal memory and activates
one of the "memory alarm" signals
when the capacity falls below the
configurable residual capacity level.
These signals can be used, for
instance, to operate the alarm relay.
The memory is written as FIFO FirstIn-First-Out, i. e. when the memory is
full, the oldest data is automatically
overwritten by the new data.
Data from the internal memory can
be shown as a history presentation
on the recorder. The size of this
memory can be configured.
Limit level to change
operating mode
Data transfer to the PC
Data transfer from the recorder to
external CompactFlash memory card
(not available with stainless steel
front), USB memory stick or via a
communications interface (USB
device, RS232, RS485, Ethernet).
Event operation
Event operation is
activated/deactivated by a control
signal (binary input, group/
combination alarm, ...). As long as
the control signal is active, the
instrument will be in event operation.
Data security
The data are stored in an encrypted
form in a proprietary format. This
ensures a high level of data security.
If the recorder is disconnected from
the supply, then:
- RAM and clock time are buffered
by a lithium battery (standard) 
10 years or with a storage
capacitor 2 days (ambient
temperature -40 to +45 °C),
Timed operation
Timed operation is active on a daily
basis within a programmable time
period. The operating modes have
different priorities.
- measurement and configuration
data in the internal memory will
not be lost.
Recording duration
Depending on the configuration of
the instrument, the recording period
can vary over a considerable range
(from a few days up to several
months).
Report
For each channel of a group, a report
(maximum/minimum/average or
integrator) can be run over defined
periods.
Batch reports
Three batch reports can be created
simultaneously in the recorder. The
measured data, start, end and
duration of each batch can be
displayed together with a batch
counter and freely defined texts, on
the recorder and within the
Evaluation Software on request, a
barcode reader can be used to start
batches and read batch texts.
Over/under limit conditions trigger
alarms. These can be used, for
instance, as a control signal to
change the operating mode.
The storage cycle and recorded
value can be configured separately
for all three operating modes.
An alarm delay function can be filter
out brief occurrences of limit
conditions, so that no alarm is
generated.
Normal operation
If the instrument is not in timed or
event operation, normal operation is
active.
Counters/integrators
27 additional internal channels are
available as counters, integrators,
operating time counters or for flow
measurements.
These counters are controlled
through the digital inputs, the alarms,
or via the logic channels. The analog
channels can be used for the
integrators.
Numerical indication is shown in a
separate window, with up to 9 digits.
The acquisition time can be selected
as: periodic, daily, weekly, monthly,
yearly as well as external, total
(overall count) or daily from ... to.
Up to 6 binary inputs are available as
high-speed counters with a 10 kHz
sampling cycle rate.
Math/logic module (option)
The module for math and logic (18
channels of each) enables, for
example, the combination of analog
channels, and also the combination
of analog channels with counters and
digital inputs. Operators for formulae
are: +, -, *, /, SQRT(), MIN(), MAX(),
SIN(), COS(), TAN(), **, EXP(), ABS(),
INT(), FRC(), LOG(), LN(), humidity,
moving average or !, &, |, ^, as well
as ( and ).
The math and logic module can only
be configured through the setup
program.

Operation and
configuration
On the recorder
The instrument is configured from
the control knob (or with stainless
steel front, from the touchpad) on the
front panel under menu guidance.
Shift current menu position
(cursor) to the left or upwards.
Shift current menu position
(cursor) to the right or
downwards.
When the control knob is
pressed, the current function is
executed.
Example:
Integrated user lists (different users
with different authorizations) protect
the recorder against unauthorized
access.
Through the setup program
As an alternative to the configuration
from the control knob on the
recorder, the instrument can also be
configured through the setup
program.
Communication between the setup
program and the paperless recorder
is made through the:

PC programs
PC Evaluation Software (PCA3000)
The PC Evaluation Software (PCA3000) is a program which runs under
Windows 2000/XP/Vista/Win7, and is used to manage, archive, visualize and
evaluate the recorder data.

The data from differently configured instruments are recognized by
the PC Evaluation Software and stored in an archive database. All
management is fully automatic. The user only has to manually allocate an
identifier (supplementary description).

The user can at any time gain access to certain data sets which can
be distinguished by the identifier. It is also possible to restrict the time
periods to be evaluated.
 Any analog or binary channels of a DataVU7 recorder (even from different
groups) can subsequently be combined into PCA groups in PCA3000.
 Since each group is displayed in a separate window, several groups can be shown simultaneously on the screen and
compared.
 Operation by mouse or keys.
 Using the export filter, it is possible to export the stored data, so that they can be processed in other programs such as Excel.
 The PC Evaluation Software PCA3000 has network capability, i.e. several users can obtain data from the same archive file
(*.177) in a network directory, independently of each other.
PCA Communications software (PCC)
 Data can be read out from the recorder via the USB device interface, the serial interface (RS232/RS485) or via the Ethernet
interface. The data can be read manually or automatically (e.g. daily at 23.00 hrs).
 Data can also be retrieved via remote control, through a modem.

USB interfaces
With USB interfaces, a distinction is
made between the host and the
device interface.
A USB memory stick can be
attached to the host interface. The
device interface, in conjunction with
a standard commercial USB cable, is
used to operate the setup program.
The paperless recorder without
stainless steel front has host and
device interfaces connected in
parallel on both the front and back
panels, of which only one of each
type can ever be used. The
paperless recorder with stainless
steel front has only one host and one
device interface at the rear panel.
RS232/RS485 interface
Current process data, as well as
specific device data, can be read via
the RS 232 or RS 485 interface.
Data in the internal memory can also
be read by the PC Evaluation
Software PCA3000 and the PCA
Communications Software (PCC).
The RS 232 interface permits a
maximum lead length of 15 m, the
RS 485 interface 1.2 km.
Connection is by a 9-pin SUB-D
connector on the back of the
instrument. Modbus (master and
slave) protocols are available, and
the transmission mode used is RTU
(Remote Terminal Unit).

start or stop batch reporting, and to

The barcode reader is operated via
the RS232/RS485 interface, and the
RS232 interface for the barcode
reader can also be used as a
Modbus master or slave.
Ethernet interface
The Ethernet interface can be
connected to local networks for
communication between the
recorder and the setup program and
the PCA Communications Software.
The IP address is set permanently
through the instrument configuration,
in the setup program or automatically
received from a DHCP server.
The integrated web server allows
simultaneous access by several PCs
to 3 HTML and 3 batch pages.
Transmission protocol: TCP/IP
Network type: 10BaseT, 100BaseT
PROFIBUS-DP interface
The recorder can be integrated into a
fieldbus system according to the
PROFIBUS-DP standard via the
PROFIBUS-DP interface. This
PROFIBUS version , in particular, is
designed for communication
between automation systems and
distributed peripheral field devices.
Data is transmitted serially according
to the RS485 standard, to a
maximum 12 Mbits/sec.
Using the included project design
tool (GSD generator; GSD = device
master file), an application-specific
GSD file is created, which is used to
integrate the recorder within the
fieldbus system.
External CompactFlash
memory card (CF)
The external CompactFlash memory
card (CF) is used to transfer the data
from the internal memory to the PC,
excluding versions with Stainless
steel front. Configuration data can be
created on the PC and then
transferred to the recorder from the
memory card.
On the PC side, data on the card is
accessed using a read/write device
(CompactFlash reader/writer).
External inputs via
interface
The paperless recorder can acquire
and store up to 24 external analog
inputs and 24 binary inputs.
Furthermore, the interfaces can be
used to enter comments in the event
list of the recorder.
