1 Purpose

1.1 Device’s Purpose

Data logger RPM-416 is a microprocessor-based device intended for electrical parameters measuring and monitoring on the data logger display as well as data archiving.

The data archiving is made on the removable memory card (SD / MMC), which can be later analyzed by software program RPM-416 Data Analysis (the program can be found on website www.novatek-electro.com), installed on the standard or portable PC. Data files have extension “RDF”.

Data logger RPM-416 has an inbuilt real time clock with power from a lithium-type battery.

RPM-416 can be connected to Ethernet network via standard 10Base-T or 100Base-T. In this case simultaneously with data recording to memory card, the RPM-416 configuration and data transmitting to the PC is possible.

RPM-416 can connect to the system Overvis (monitoring and remote control www.overvis.com).

The main possibilities of the data logger:

Multi-channeling – one data logger is sufficient for all working data receiving from the controlled device
Versatility – the additional modules can be connected to the data logger which makes it possible to expand the range of incoming signals (voltage, current, temperature, discrete inputs, etc.)
Galvanic separation – incoming signals of high voltage and current are galvanic separated from other inputs which ensures easiness of data logger connection
High fidelity – self-control system and data saving algorithm protect against data loss in case of emergency situations (power supply failure)
Servicing convenience – four-lined symbolic display with illuminating enables to adjust the data logger and monitor its work (the values of recorded incoming signals are shown on the display), the keyboard is used for setting and control of the data logger
Remote monitoring and configuration – if the data logger is installed in a hard accessible place with Ethernet connection it can simultaneously with the data recording on the memory card make data transmitting to PC. It enables to make a remote monitoring of the object. The more detailed analysis can be made on the basis of the data stored on the memory card. Web-interface enables via PC browser to make a remote configuration of the data logger without installing any other additional programs. FTP provides remote access to the memory card to retrieve or delete files.

4. Design and Operation Principle

4.1 Design

RPM-416 is constructively made in a plastic case intended for fixing on DIN-rack 35 mm, case dimensions (91×157×56.3 mm) 9 modules of S type. The case is made of crashworthy, self-extinguishing material.

4.2 Operation Principle

The data logger operation principle is based on measuring values from all sensors connected to the data logger inputs, accumulating the data in the data logger internal memory and data recording to the external memory storage – memory card (SD / MMC).

4.3 Real Time Clock

The data logger is equipped with an inbuilt real time clock which is powered (in case of main power failure) from an inbuilt backup power cell – lithium type battery. The power from the backup supply is sufficient for continuous operation of the real time clock during 10 years (at temperature 25 ºС). In case of data logger operation at temperatures on the limits of the working range, the working period of the clock decreases.

5. Connection

5.1 Preparing for Connection

Unpacking the device (we recommend saving the original package throughout the guarantee life period of the device);
Ensure that the device has no damages after transportation, in case of such refer to supplier or maker;
Check the completeness of set (see section 2), in case of non-completeness refer to supplier or maker;
Study User’s Manual carefully (special attention should be paid to the power supply connection diagram of the device);
If there are issues concerning device’s installation, please refer to the maker by phone indicated in the end of this Manual.

5.2 General Instructions

If the temperature of the device after transportation or storage differs from the environment temperature at which it is expected to operate, then before connection to electric mains keep the device under operating conditions within two hours (because the device elements may have moisture condensation).

To ensure the reliability of electrical connections, one should use flexible (stranded) wires with insulation for a voltage not less than 450 V. Recommended cable cross-sections to measure current is within 1.5 – 2.5 mm², for the rest of connections it is within 0.75 – 2.5 mm². The wire ends should be cleared from insulation for 5±0.5 mm and clamped by a sleeve lug. Fixation of wires should exclude mechanical damages, twisting and abrasion of wires’ insulation.

When reducing the tightening torque, the junction point is heated, terminal block may be melted and wire can burn. If you increase the tightening torque, it is possible to have thread failure of terminal block screws or the compression of the connected wires.

For reduction of electric field influence, the installation of “data logger-sensor” lines should be made as a separate route (or several routes). The routes should be located separately from power cables as well as away from cables which make high frequency and impulse noise. The routes should be planned in such a way that the length of signal lines is minimal.

The connection of expansion modules is made with the help of cable CEM-11-1 (see section 5.4, the cable is supplied along with every expansion module).

The connection of the data logger to Ethernet network is carried out by the cable made according to the standard ANSI EIA TIA 568B (see section 5.5, the cable is supplied along with the data logger).

During use of backup power supply, the connection is made to the same terminals as the main power source. It is necessary to have a scheme ABI (Automatic Backup Input) for switching from the main power source to the backup power supply.

For ensuring continuous data recording, ABI should switch power supply to backup source within a period not more than 0.5 sec.

5.3 Connection Diagram

The connection of RPM-416 is made according to the scheme shown in Figure 5.1.

In order to improve safety in the power circuit, it is recommended to install a fuse with nominal value of 3.15 A.

Connection diagram of RPM-416

FU1 – The fuse (circuit breaker) for current 3.15 A

Figure 5.1 – Connection diagram of RPM-416

5.4 Connection of Expansion Modules

Up to 4 expansion modules can be connected to the data logger at the same time. At attempt to add more than the specified quantity of modules, the RPM-416 stops perceiving all modules and switches them off.

The expansion modules installation should be carried out with the data logger power being switched off.

The module connection should be made with cable CEM-11-1 (not supplied with the data logger).

The number indication of cable CEM-11-1 terminals is shown in Figure 5.2.

Number indication of cable CEM-11-1

Figure 5.2 – Number indication of cable CEM-11-1

One end of the cable is connected to the socket RJ11 located in the data logger as shown in Figure 5.1, the other end of the cable is connected to the socket RJ11 located in the expansion module.

The connection linkage is made automatically after power input to the data logger.

The cable CEM-11-1 is supplied with every expansion module.

5.5 Connection to Ethernet Network

Connection of the RPM-416 to Ethernet network is carried out via the cable made according to the standard ANSI EIA TIA 568B category Cat.3 and higher (supplied with the device).

The numeral indication of such cable is shown in Figure 5.3.

Numeral indication of cable for connection to Ethernet

Figure 5.3 – Numeral indication of cable for connection to Ethernet

One end of the cable is connected to the socket RJ45 located in the data logger as shown in Figure 5.1, the other end of the cable is connected to the socket of network adapter located in the PC or other network device.

LED indicators, located near the socket RJ45 indicate:

green – data interchange;
yellow – communication.

For communication connection via Ethernet interface, the data logger and PC should be in the same IP-subnet.

Programming of the RPM-416 while connected to Ethernet network is described in Appendix A.

Programming of the RPM-416 while connected to Internet network is described in Appendix B.

6.1.5 Data Recording at Event

RPM-416 can make data recording at event (this mode is described in the Setting of Event Recording Mode section).

If the data recording at event is switched on, the values measured by the data logger are continuously being recorded in temporary buffer storage with a user defined periodic sequence (parameter “Discreteness” at default is 1 ms). Maximal length of temporary buffer storage is 1480 recordings.

The buffer storage is sequential data, where the reading is performed from “beginning” and recording is made to “end”. When the buffer is full, the data deleting is performed from “beginning” and the new data is located in “end”.

In RPM-416 there are five available sources of events, every of which can be set individually to any of the data logger inputs.

Until the event happens, the data logger continuously checks the measured values with the up and down limits specified by the user during the event setting. If the measured value is higher (up limit) or lower (down limit), the event is generated.

After the event happens, the data recording is performed in three stages, as shown in Figure 6.9.

Data recording at event (stages)

Figure 6.9 – Data recording at event (stages)

At the first stage, the values accumulated in the temporal buffer storage are recorded.

At the second stage, the value generated the event is recorded.

At the third stage, after event changed values are recorded.

After completion of all stages of recording, the data logger goes to stand-by mode waiting for a new event.

The number of values recorded before and after the event is set by parameters “Points before” and “Points after” in the menu of events setting (see Setting of Event Recording Time).

If the limit of the event is set for a single recording (“ONCE”, see Setting of Upper and Lower Thresholds), then there will be no generating of the next event if the measured value is lower (up level) or higher (down level) of specified limits.

If the event limit is set on continuous recording (“LONG”, see Setting of Upper and Lower Thresholds), then after the event happens the data recording will continue, until the measured value is higher (up level) or lower (down level) of specified limits.

For entering the data logger main menu: on the main screen by buttons ◄ (left) or ► (right) select item “MENU/МЕНЮ”, and by button ◙ (enter) confirm the selection. If the password was set before, the data logger asks to enter the password (Fig. 6.10 Screen of password entering).

6.2 Use of HTTP Server (Web-interface)

For access to Web-interface of the data logger, a PC with an installed Web-browser is required.

In the Web-browser, enter the IP-address of the data logger (factory setting 192.168.0.2) and press the button to access this address.

On the PC screen there will be a welcome page of the data logger RPM-416 with offer to enter the password (factory setting “admin”).

After the password entering and pressing the button “Enter”, if the password is correct, there will be the main screen of the data logger. If the password is not correct, there will be a password error message on the PC display.

On the main screen you can monitor the current state of the data logger, make settings, control and restart.

After resetting RPM-416, press the button “Save setting”. The entered settings will be checked. In case there are no errors in the setting parameters, they will be saved in nonvolatile memory of the data logger. In case there are some errors in the setting parameters, they will not be saved.

After the completion of the work with Web-interface, press the button “Exit”. The main page will be closed and the welcome and password page will be opened.

If there is no activity of the user during 5 minutes (this period is specified by the user, see Setting of HTTP Connection Timeout), the data logger automatically closes the communication. In this case it is necessary to enter IP-address of the data logger and password again.

6.3 Use of Modbus TCP Server

Connection protocol Modbus TCP enables connecting the data logger to the network organized by standard Ethernet. The use of the data logger in network enables to perform the following operations:

data receiving in SCADA systems;
programming the data logger via PC (by program RPM-416 Data Analysis);
remote control of the data logger.

While connecting to the data logger, the access to the command registry and recording function is blocked (reading function is not blocked). To unblock the access to the command data logger and recording function, write in registries 51-63 the modbus password in ASCII symbols (factory default “admin”). In unused registries, there should be written zero values (0x0000).

In case the modbus password is correct, the data logger will unlock the access to the command registry and recording function.

The data logger control is carried out via the command registry (see Modbus Registers Reference).

After completing data logger resetting, carry out the command of recording in the nonvolatile memory (0x472C). For the changes to take place, the data logger should be restarted (0xF2C5).

If the functions of recording and register of commands are not used for a long period of time, block the access to them by writing in registries 51-63 values differing from the modbus password (for example, 0).

If there is no data exchange for 60 seconds (time is set by the user, see Setting of Modbus TCP Connection Timeout), the data logger automatically breaks the connection with the client.

In the data logger, all values with a decimal point are converted to whole numbers. That’s why while processing the data, it is necessary to use additional mathematic operations.

To the request of reading the value with a dot (for example, 1.000) the data logger will return the whole number value 1000, for adjusting to the correct format it is necessary to divide the number by 1000.

Before recording the value with a dot (for example, 1.000) it is necessary to bring the value to the whole number by multiplying by 1000, then make recording of the value in the data logger.

The coefficient of changing to whole number is defined by the number of digits after the dot (1.0 – 10; 1.00 – 100; 1.000 - 1000).

The types of parameters and their names are given in the Parameter Types table.

The list of supported Modbus functions is in the Supported Functions table.

The command registry address is in the Command Registry section.

Addresses of additional registries are in the System Registries section.

Addresses of the registers of the measured parameters of the base channels are given in the Base Channel Registers section.

Addresses of programmable parameters are in the Programmable Parameters section.

For the complete Modbus register map including supported functions, command codes, parameter types, system registries, and channel addresses, see Appendix E: Modbus Registers Reference.

6.4 Use of FTP Server

File transfer protocol FTP uses the double connection. One channel is a control channel through which the commands from the data logger come in and responses go out (default TCP-port 21), and via the second channel comes data communication (TCP-port is defined by the data logger by random choice).

Use of FTP protocol enables via TCP-networks to receive remote files recorded by the data logger on the memory card.

Files receiving is carried out with the help of program “RPM-416 Data Analysis” or any other software which supports file receiving via FTP.

In the data logger, server FTP operates in passive mode (waiting for the client’s connection).

At connection to the data logger via FTP it is necessary to write the name of the user “ftp” and password (factory default “admin”).

Supported FTP commands:

ABOR – Abort the file transmitting
CDUP – Change the directory upward
CWD – Change the directory
DELE – Delete file
LIST – Restore the list of current directory files
MKD – Make directory
MODE – Sets the transfer mode (“S” – Stream)
NLST – Restore the list of current directory files in brief format
NOOP – No operation (is used for timeout reset)
PASS – Password for the server
PASV – Enter in passive mode and restore address of connection
PORT – Specifies an address and port to which the server should connect
PWD – Restore the current directory
QUIT – Switch off
REIN – Re-initialize the connection
RETR – Download the file (before RETR operation there should be a command PASV)
RMD – Remove a directory
STOR – Accept data and store data as a file at the server site
STRU – Set file transfer structure (“F” – file)
SYST – Return the system type (UNIX)
TYPE – Define the type of file transmitting (“I” – binary)
USER – User’s name for input on the server

If there is no data exchange during 300 seconds (time period can be set by the user, see Setting of FTP Connection Timeout), the data logger automatically breaks the connection with a client.

6.5 Use of Overvis Client

Overvis is a system for monitoring, visualization and remote control of technological processes.

Overvis enables:

to read the data from the instruments, including with the recording system;
to perform 24-hour cyclical readout of data;
to save the data automatically in its own database;
to display the data in the convenient form;
to receive alarm reports in the form of SMS or E-Mail.

More detailed information can be found at the official website www.overvis.com.

Overvis system acts as a collection server of data from the recording system and other devices connected simultaneously, and it provides access to data in real time only with the permission of the owner of the recording system.

Factory settings of the recording system are prepared to connect to the server of Overvis, in this case the Overvis client in the recording system is disabled and should be enabled manually by the user.

To connect the recording system to the system of Overvis it is required:

Configure the recording system to access the internet
Enable Overvis Client
In the Overvis settings, make sure that there is connection to the server and the activation code is received
Using the instructions at Overvis website, connect to the recording system with the activation code

6.6 Inserting and Pulling Out of the Memory Card

Insert the memory card in the slot situated on the side wall of the data logger, as shown in Figure 5.1 and press it till there is a click.

In order to pull the memory card out, press it till a click and release it – the memory card will go out from the slot about 3-5 mm, after that you can pull it out.

During inserting and pulling out of the memory card do not use much effort.

6.7 RPM-416 Data Analysis Software Installation

For proper work of the software on the computer there should be installed Operational System Windows Vista or Windows 7/8/10/11. The installation is initiated by starting the installation file “rpm416da_setup.exe” (not included in the supply scope).
