2. GENERAL CHARACTERISTICS

• Multifunctional

Device is designed for recording, displaying current or averaged values and presentation of technological parameter trends in graphic form.

• Large data storage capacity

The registered measurement results are recorded in the unit's memory. The capacity of installed memory allows to store:

–

over 500 000 measurements (2MB) for units equipped with RS-485 interface

–

over 2 000 000 measurements (8MB) for units equipped with RS-485 interface and USB Host port.

• Configurable measurement and control input

The unit has up to 8 channels (depending on version) of measurement signals and one digital voltage input with programmable functions, e.g. control of the recording process. Each signal can be freely configured and described. Depending on device version all measured parameters must be available as current type signals (0-20 mA or 4-20 mA standards) or resistance (Pt100, Pt500 or Pt1000 standards). The internal analogue-digital converter has a 12 or 16 bit resolution (depending on input type), which provides high measurement resolution results. Additionally, individual alphanumeric description (text) of each of the recorded channels is possible.

• Fast serial interface

The data logger is fitted with a galvanic isolation RS-485 interface, programmed with ModBus RTU transmission protocol. This enables the connection of a number of data recorders into the network, remote collecting of data from each unit and also remote configuration. The application of the RS-485 interface instead of RS-232 is due to the possibility of achieving high transmission speeds using transmission lines of larger length than is possible with the RS-232 interface.

• Built-in USB Host interface (optional)

Optionally the device can be equipped with built-in USB Host interface, allowing for data transfer to popular USB Flash Drives (PenDrives). This method allows for significant simplification of unit application: it is no longer necessary to connect PC and data logger via RS-485 interface. Significant acceleration of data transfer is an additional advantage: data download can be 10 times faster than using RS-485 interface.

WARNING!

Device should work properly with any standard Flash Drives, but manufacturer can not guarantee proper cooperation with non-standard devices, or with devices developed after data logger release.

User manual - DATA RECORDER SRD-99 and cooperating software

• Wide range of power supply voltage and external sensor power supply

The built-in pulse power supply allows power to be supplied to the unit with

85...

230

...260V AC/DC voltage or 16...24...35 AC, 19...24...50 DC voltage (depending on version). Data logger (version with current inputs only) is equipped with voltage output for powering the sensor and converters: 24V DC ±5% / max. 200mA.

• Legible graphic display

The 128 x 64 points display with a backlight mounted on front of the unit is a big advantage of the data recorder. It allows the display of trend graphs for each channel separately. Different operation modes provide the possibility of selecting and adjusting the method of data presentation depending on the user's requirements. Data recording intervals are selected by the user from the menu level. Additionally, it is possible to set the display to show one current value measured for a selected channel.

• Easy configuration

There are 6 keys on the front of the data recorder that enable the configuration of the unit. The menu assisted with full text descriptions makes the unit configuration process quite easy. However, due to a significant number of configured parameters it is advised to use the attached configuration software for PCs.

4. DEVICE INSTALLATION

The unit has been designed and manufactured in a way assuring a high level of user safety and resistance to interference occurring in a typical industrial environment. In order to take full advantage of these characteristics installation of the unit must be conducted correctly and according to the local regulations.

- Read the basic safety requirements on page 4 prior to starting the installation.

- Ensure that the power supply network voltage corresponds to the nominal voltage stated on the unit’s identification label.

- The load must correspond to the requirements listed in the technical data.

- All installation works must be conducted with a disconnected power supply.

- Protecting the power supply connections against unauthorized persons must be taken into consideration.

4.1. UNPACKING

After removing the unit from the protective packaging, check for transportation damage. Any transportation damage must be immediately reported to the carrier. Also, write down the unit serial number located on the housing and report the damage to the manufacturer.

4.2. ASSEMBLY

- The unit is designed for mounting inside housings (control panel, switchboard) inssuring appropriate protection against surges and interference. Metal housings must be connected to ground in a way that complies with the governing regulations.

- Disconnect the power supply prior to starting assembly.

- Check the connections are wired correctly prior to switching the unit on.

In order to install the unit, a 90,5 x 90,5 mm mounting hole (

Fig. 4.1

) must be prepared. The thickness of the material of which the panel is made must not exceed 5mm. When preparing the mounting hole take the grooves for catches located on both sides of the housing into consideration (

Fig. 4.1

). Place the unit in the mounting hole inserting it from the front side of the panel, and then fix it using the brackets (

Fig. 4.3

). The minimum distances between the center points of multiple units - due to the thermal and mechanical conditions of operation - are 115 mm x 115 mm (

4.3. CONNECTION METHOD

Caution

- Installation should be conducted by qualified personnel. During installation all available safety requirements should be considered. The fitter is responsible for executing the installation according to this manual, local safety and EMC regulations.

- The unit is not equipped with an internal fuse or power supply circuit breaker.

Because of this an external time-delay cut-out fuse with a small nominal current value must be used (recommended bipolar, max. 2A) and a power supply circuitbreaker located near the unit. In the case of using a monopolar fuse it must be mounted on the phase cable (L).

- The power supply network cable diameter must be selected in such a way that in

the case of a short circuit of the cable from the side of the unit the cable shall be protected against destruction with an electrical installation fuse.

- Wiring must meet appropriate standards and local regulations and laws.

- In order to secure against accidental short circuit the connection cables must be

terminated with appropriate insulated cable tips.

- Tighten the clamping screws. The recommended tightening torque is 0.5 Nm.

Loose screws can cause fire or defective operation. Over tightening can lead to damaging the connections inside the units and breaking the thread.

- The separable clamps should be inserted into appropriate connectors in the unit,

even if they are not used for any connections.

- Unused terminals (marked as n.c.) must not be used for connecting any

connecting cables (e.g. as bridges), because this can cause damage to the equipment or electric shock.

115 mm

Page 14

User manual - DATA RECORDER SRD-99 and cooperating software

- If the unit is equipped with housing, covers and sealing to, protecting against water intrusion, pay special attention to their correct tightening or clamping. In the case of any doubt consider using additional preventive measures (covers, roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric shock.

- After the installation is completed do not touch the unit’s connections when it is switched on, because it carries the risk of electrical shock.

Due to possible significant interference in industrial installations appropriate measures assuring correct operation of the unit must be applied. To avoid the unit of improper indications keep recommendations listed below.

Avoid running signal cables and transmission cables together with power supply cables and cables controlling inductive loads (e.g. contactors). Such cables should cross at a right angle.

Contactor coils and inductive loads should be equipped with interference protection systems, e.g. RC-type.

Use of screened signal cables is recommended. Signal cable screens should be connected to the earthing only at one of the ends of the screened cable.

In the case of magnetically induced interference the use of twisted pair of signal cables is recommended. Twisted pair (best if shielded) must be used with RS-485 serial transmission connections.

In the case of measurement or control signals are longer than 30m or go outside of the building then additional safety circuits are required.

In the case of interference from the power supply side the use of appropriate interference filters is recommended. Bear in mind that the connection between the filter and the unit should be as short as possible and the metal housing of the filter must be connected to the earth with the largest possible surface. The cables connected to the filter output must not be run with cables with interference (e.g. circuits controlling relays or contactors).

Connections of power supply voltage and measurement signals are executed using the

screw connections on the back of the unit’s housing.

Excessively high temperatures cause faster ageing of the internal components and shorten the fault-free time of the unit's operation. In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with small amount of detergent or in the case of more significant contamination ethyl or isopropyl alcohol.

Using any other agents can cause permanent damage to the housing.

Product marked with this symbol should not be placed in municipal waste. Please check local regulations for disposal of electronic products.

6. PRINCIPLE OF OPERATION

After turning the power supply on, the logo and basic unit data are showed on the

display, then the unit goes to the measurement mode.

6.1. MEASUREMENT MODE

In the measurement mode the unit executes the measurement of values of signals connected to measurement inputs, hereafter called measurement channels (the number of available channels depends on the unit version). For each channel measurements are conducted at the frequency of 8 times per second (I version

and

U version), 1 time per 2.5 seconds (RTD version) or 2 times per second (TC version). The results of the conducted measurements are shown on the LCD display. The unit computes the measurement results into indicated values proportionally (linear).

All available parameters of the unit’s operation can be configured in the main menu (see

DEVICE PROGRAMMING

) or using the RS-485 interface and software installed on your PC.

Configuration of the device (via menu or RS-485 interface)

do not stops the data

recording process .

Results of measurements conducted for active (selected by the user) channels of the unit are displayed in one of the available result presentation modes (see

)

The range of displayed values, unit of measured value and position of the decimal point

(for presentation in numeric form) and name of channel are defined by the user.

6.1.5. Recording momentary and averaged data

Values corresponding to the results of current measurement conducted for each channel can be recorded (stored in the non-volatile memory of the unit) for further analysis. The recording of measurement results for all channels is performed with the same frequency, defined by the user in the range between 1 record per second to 1 record per hour ("

Rec. period

" parameter). Recording times are synchronized with the internal real time clock. Recording can be stopped at any moment with selected status on digital input of the unit ("

Triggering

" parameter).

In order to enable more advanced mathematical processing of recorded signals it is possible to set the unit's options to record averaged measurement results. Setting the recorded value type to

averaged value

(parameters "

Channel 1

"... "

Channel 8

", depending on the number of channels in the unit) causes that instead of momentary values the unit records in its memory values that constitute the average results of measurements conducted during the set

recording period

. All measurements conducted by the unit shall be averaged,

irrespective of the set recording frequency.

The principle of recording measurements is presented in

Fig. 6.5

. In the case of recording

Fig. 6.5. Principle of measurement recording

Averaging operation concerns

only

the type of recorded values; it does not concern the method of presentation of current measurement. In all result presentation modes, indications - described in the remaining part of the manual as results of measurements not recorded in the unit's memory - correspond to the momentary value of the measured signal.

Averaged values can be viewed in the data logger only in the "

Measurements list

" and

Graph

" results presentation mode, because these modes enable presentation of values recorded in the unit's memory. Averaged values can also be viewed in the database downloaded by the software working with the data logger.

In the case of multiple changes of type of recorded value (momentary values of averaged values) there is no possibility to distinguish whether data recorded in the memory concerns momentary measurement value or averaged measurement results.

Recording the measurement results in the non-volatile memory can be executed in two modes: "

until full

" or "

cyclic

" ("

Write

" parameter). The first mode enables the recording of such amounts of data as the unit's memory allows for, then the recording is stopped. In the second mode, once the memory is full, the results are recorded from the starting address in the memory, overwriting existing measurement results. The time remaining until the memory is full is displayed once the unit is started and in the "

Device information

" menu, available in the

units main menu.

In the case of both modes, once the memory is full, a warning message is displayed (see description of "

Write

" parameter in the "

Logging setup

" menu). The recorded data should be periodically downloaded to a PC using appropriate software or USB FlashDrive (method recommended for data loggers equipped with 8MB of memory).

All parameters concerning the recording m ode, the influence of digital input on the recording method, the recording frequency and type of recorded value are available in the "

Logging setup

6.3.3. Example of output control

Outputs have limited current rating.

Do not

use outputs to supply external devices that requires a lot of power like heaters, motors or others. Instead, use external supply devices like power relays or others that can be controlled by output.

If simple temperature control in some room is required this device can be used to do this. Assuming there is a heater and cooler that we can control by outputs and single temperature sensor. We must connect a sensor to some input, output 1 to control the heater and output 2 to control the cooler. The input channel where temperature sensor is connected must be configured correctly (in this example it is assumed reading is in Celsius degree).

If lower limit of the temperature when heater should be turned on is 18 degree and upper limit when cooler should be turned on is 27 degree, alarm settings should be as follows (assuming decimal point ”

0.0

”):

”

AL1 mode

” - ”

under threshold

”

Threshold 1

” -

19.0

”

Hysteresis 1

” -

1.0

”

AL2 mode

” - ”

over threshold

”

Threshold 2

” -

26.0

”

Hysteresis 2

” -

1.0

When alarm 1 is generated this means that the temperature reaches 18 degree (

19.0

–

1.0).

When temperature reaches 20 degree (

19.0+1.0

) alarm 1 will disappear. Similar, when

temperature reaches 27 degree (

26.0

1.0

) alarm 2 will appear and when temperature

reaches 25 degree (

26.0

–

1.0

) alarm 2 will disappear.

Now we have to configure outputs to use those alarms. In ”

Outputs settings

” menu

fallowing example parameters must be set:

• All time type parameters which describe outputs, can be set in range 0 ÷ 9999 with resolution of 1 sec.

• Because of computing precision, the time is shorter about 2.5% than the entered value. This means if time is set to 100.0s the real time will be shorter about 2.5s.

Fig. 7.28. ” Outputs settings” menu.

7.4.10. ”Date & time settings” menu

Menu allows to change date and time of internal clock (RTC):

”Time”

- current time according to the unit’s real time clock,

”Date”

- current date according to the unit’s real time clock,

”Apply”

- this option enables the internal real time clock to be set according to values of the

“

Time

” and “

Date

” parameters.

After entering the menu the current indications of the internal clock are displayed. The changing of parameters (

“Time”

“Date”

) stops the indications updating. Changed

parameters must be stored using the

“Apply”

option.

Reversing the Data Logger unit’s clock (date and time) shall delete all data recorded by the unit, the recording time of which was later than the new time. In order not to lose the recorded data, it must be downloaded to a PC before the clock is reversed.

7.4.11. ”RS485 port settings” menu

This menu contains options to configure the RS-485 interface:

”Address”

- this parameter specifies the unit’s address, according to the Modbus protocol (in the range of 0 to 99). If the address is set as 0, then the unit responds to the FFh address.

”Baud rate”

- this option defines the RS-485 serial interface transmission speed. 8 possibilities are available: ”

1200

”, ”

2400

”,”

4800”, ”9600

”, ”

19200”, ”38400

”, ”

57600

”, ”

115200

” b/sec.

Default baud rate value is 115200 b/sec. Some RS-485 converters may not work properly with this setting. In such a case set lower baud rate (according to converter data sheet).

”Resp. delay”

- this parameter defines minimal (additional) delay between the Modbus message and the answer of the device (received and sent via RS-485 interface). This additional delay allows the device to work with poor RSconverters which do not works properly on baud rates higher than 19200. This parameter can be set to one of values:

”stand.”

- device responds without any additional delay

”+10 ch.” ”+20 ch.” ”+50 ch.” ”+100 ch.” ”+200 ch.”

The unit response with additional delay equal to transmission time of 10, 20, 50, 100 or 200 characters.

In the most cases parameter

”Response delay”

should be set to

”Stand.”

(no

additional delay). Unfortunately for some third party RS-converters

”Response delay”

should be adjusted experimentally. Table below contains most

frequently used values.

”Baud rate” parameter

7.4.12. ”Access setup” menu

This menu contains options controlling access to the unit’s adjustable parameters and to

data downloading function (using USB Host port):

”Password for menu access”

- menu access password (4-digit number). If the parameter is

set to “

0000

” the password is disabled. If the parameter is different from

“

0000

” then menu access requires password to be entered.

If the user do not remember his password, the access to the menu is possible by the

“one-

use password”

. To get this password please contact with Marketing Division. Please set new

user password immediately after use of the

“one-use password”

”Password for USB disk write”

- password for data downloading to the flash disk (4-digit

number). If the parameter is set to “

0000

” the password is disabled. If

the parameter is different from “

0000

” then data downloading to

unregistered flash disk

- PenDrive requires password to be entered

(registering can be done using

”Register the disk”

option).

”Register the disk”

- this function allows registering (unregistering) single USB type

FlashDrive (PenDrive). Data can be stored on

registered

flash drive

without entering of the password.

Fig. 7.31. “Access setup” menu

7.4.13. ”USB options” menu

This menu contains options which allows copying of device configurations between PC

and data logger unit, and automatic data transfer using USB type FlashDrive (PenDrive):

Page 58

User manual - DATA RECORDER SRD-99 and cooperating software

After selection one of options above device waits for plugging in of FlashDrive. If disk is found then device displays the message which allows approving or cancelling selected operation.

Fig. 7.32. “USB options” menu

To return to

”USB options”

menu, after finished reading or writing of configuration,

FlashDrive should be unplugged or any key pressed.

If error occurs while reading or writing proper message is displayed. User have to confirm this message using

[ENTER]

”Automatic write of registered data”

- this option allows activating of automatic data storage to the Flash Drive plugged to USB socket.

Automatic data writing is made periodically, after recording about 70 kB of new data,

what keeps the usage of internal memory below about 1%.

Autostorage frequency depends on recording settings (number of channels, and recording period). Minimum period between successive data storages is about 50 min. (8 channels recorded every 1 sec.).

• In case of error while auto data writing, device displays a proper message and waits for user acknowledge. While waiting for acknowledge,

DEVICE DOES

NOT EXECUTE ANY AUTOSTORAGES

, but all data is recorded to internal memory of the device. Due to the possibility of occurrence of: write error, FlashDrive or USB malfunction, and other incidental problems, autostorage function should be controlled by user from time to time. Lack of control can cause overwriting of data in internal memory or stopping of data recording due to impossibility of data storage on FlashDrive.

• If “

Password for USB disk write

” parameter has been set, then after power off / on sequence it is necessary to enter this password to run “Auto data write” function. To omit this requirement it is recommended to use function “

the disk

” or disable of “

Password for USB disk write

”.

• While “Auto data write” is active and FlashDisk is plugged to USB connector,

pressing the

[ENTER]

key in any presentation mode will force the storage of

current data to the Flash Drive (other functions of

[ENTER]

key are disabled).

To allow default functions of

[ENTER]

button, it is necessary to unplug Flash

Drive from USB connector.

• Depending on the recording settings, periods between successive storages can

be long. To be sure that current data (up to now) had been written, force data storage (pressing

[ENTER]

in any data presentation mode) before disconnecting

the Flash Drive from USB (see the previous note).

" and

“

Upper ext.

”, “

Lower ext.

” parameters then 01h ÷ 08h registries shall contain limit values for the allowable range.

Exceeding the allowable measurement range shall be signalled by setting appropriate bits of the 09h registry. 2 - after writing registry 20h the unit replies with the frame starting from the old (unchanged) address 3 - after writing registry 22h the unit replies with the frame sent according to the new baud rate 4 - status of “

Triggering

” parameter in “

RS485 port settings

” submenu also relates to the writing of this parameter; therefore it is possible to block writing of all registries using the RS-485 port, but unblocking can be made only through the device's menu.

9.2. TRANSMISSION ERRORS HANDLING

If during reading or writing one of registries an error occurs then the unit shall return the frame containing the error code (according to the Modbus protocol, see: example No. 5, page 71).

Error codes should be interpreted as follows:

01h

- illegal function (only functions 03h, 06h and 10h are available),

02h

- illegal register address

03h

- illegal data value

08h

- no write permission (see: “

Config change

” parameter in the “

RS485 port settings

”

menu)

Downloading of registered data

Downloading of data stored on internal memory can be done in two ways:

• using USB FlashDisk (PenDrive)

• using RS-485 interface

Data downloading from Flash drive and selected localisation

The USB FlashDisk will be automatically detected if inserted to PC USB port, and the user will be asked for confirmation of data download (if any data available on the inserted disk).

Loggy Soft

allows to download data from any localisation (selected directory) by means

[Download data (file)]

button. This method should be used only if the logged data was

previously copied manually from FlashDrive to PC hard drive.

Data downloading via RS-485 interface

Default settings of data downloading via RS-485 allow to import only newest data, stored since last downloading. This method prevents user against multiply downloading of stored data, and reduces time of data downloading. Date of last download is automatically stored to internal memory of logger while downloading initialised by pressing of

[Download data

(RS485)]

button.

In some cases there is a need to download already downloaded data again (failure of the device, errors in database, lost of downloaded data). In such situations it is possible to download data more than one time, but only if data is not overwritten or damaged.

Page 96

User manual - DATA RECORDER SRD-99 and cooperating software

To download data again enter

Advanced Settings

(password is required), then disable

Auto

option and select date of the begin of required data (

Fig. 3.16

). After that click

[Download

data (RS485)]

button.

Fig. 3.16. Downloading data using RS-485 interface (advanced options active)

If data downloading is broken unexpectedly or data is incomplete it can be result of database damage. In such situation try download data again but omit damaged part of data (range of time). For example if data were logged every 15 minutes, and data downloaded lastly were stored

2009-07-28 17:15

, then set parameter

„From date:”

omitting one or more

data points. To omit one point only, set

again.

Data can also be downloaded automatically at specific time intervals. Although the memory capacity of device allows data logging at least for day, this functionality is especially useful for continuous data protection on the server. A more detailed description of automatic data download can be found in chapter

Page 98

User manual - DATA RECORDER SRD-99 and cooperating software

Typical methods of grouping measurement channels:

• measurement channels recording the measurements of the same physical value (e.g. temperature or humidity),

• measurement channels recording the measurements from sensors located in the same places, e.g. “Assembly room”.

One measurement channel can belong to different groups.
