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.

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).

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),

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.

Limit level to change operating mode

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.

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.

Timed operation Timed operation is active on a daily basis within a programmable time period. The operating modes have different priorities.

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.

Ref DS-VU7-1-EN-0212

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:

Rotate control knob to the left.

Press control knob.

Result: The menu for the alarm and event list is called up.

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:

- USB device interface,

- serial interface,

- Ethernet interface,

- CompactFlash memory card or

- USB memory stick.

The configuration data can be archived on a data storage medium and output to the printer.

On the PC side, the web server can be addressed with web browser. For visualizing graphics, an SVG Viewer (from Adobe®, for instance) must be installed on the PC in addition to the Internet Explorer.

Process images (editor)

The setup program can create process images and transfer them to the paperless recorder for display. Up to 25 objects (images, analog channels, binary channels, texts, ...) can be used in a process image.

Rotate control knob to the left.

Press control knob.

Result: The menu for the alarm and event list is closed again.

Operating language

Two languages (see order details) are integrated in the instrument exfactory. The setup program is used to change the operator language. The languages available: English, French, German, Russian, Japanese, Chinese, Italian, Romanian, Czech, Hungarian, Polish and Greek. Other language versions (with Unicode capability) can be created.

Web server

The web server is integrated in the DataVU7 as standard. Four different modes of presentation are available:

online visualization

three freely programmable HTML pages

current batch reports

4-way view (1 to 4 recorders or

different visualizations)

One process image is integrated in the paperless recorder ex-factory.

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).

RS232 for barcode reader

A barcode reader can be used to start or stop batch reporting, and to

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.

Ethernet PROFIBUS-DPExternal

CF card

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.
