SPECIFIC WARNINGS

To guarantee the IP protection during the installation, expect to seal the instrument cables (with silicone or foam) after having tightened the cable-gland. Through the installation expect suitable protections to avoid product overheating (eg. a shelter to avoid direct sunlight); similarly for low temperatures. Do not open in case of bad weather conditions (rain, snow, etc). Expect the recurring substitution of the hygroscopic salts. Do not install in small locations and/or without ventilation, with high humidity, in potentially dangerous areas or where is prescribed the use of explosion proof components. Electrical connections on the product must be executed only from qualied and expert personnel, in compliance with actual rules and regulations. For external network powering, the plug at the end of the cord has ground contact; the grounding of the powering is provided from the plug inserted in the socket. The product powering source must be divided from dangerous voltage parts with double insulation and must guarantee an insulation of at least 3000 Vrms. Be sure to have, in the plant, a suitable protection from electric short circuit (for example high sensitivity differential circuit-breaker at the root of the AC/DC power supply unit). Before any maintenance on the product, the powering must be disconnected. Avoid any action that can short-circuit the rechargeable battery poles. To enable the product protections, expect a connection to the ground plant through a proper green-yellow grounding connector; this connector must be connected to the proper ground clamp (or to any bolt if it is a metal cabinet). Verify periodically rechargeable battery voltage; expect a substitution after roughly 5 years and if the voltage measured on the poles is too low (eg. 10.5V for a battery with nominal voltage 12V) and investigate on the causes. Using the product differently from the one expected from the manufacturer can compromise safety conditions. The use of parts other than original spare parts could lead to irregular functioning or even dangerous situations for person and things.

Connections

Front Panel

Figure 2

The majority of connections are located In NI2400’s front panel:

• RS-232: it can be used to connect a 3G Modem to expand connectivity

• Ethernet: This port is used to connect the device to an existing LAN. Internal Web Server can be browsed to configure and download acquired data. It can be used for Internet connection (Cloud, FTP and EMAIL connections)

• USB Host: it allows the user to download measures, events and alarm logs to a pendrive, or to update the firmware

• V OUT: this connector is designed to output the same voltage applied to V IN. It can be turned off automatically when logger is in sleep mode or be kept always on.

• RS-485#2 – V OUT: This is SmartMux port, which allows the connection of 16 SmartMux in daisy chain and offers power supply.

• RS-485#1 – V OUT: This is SmartModbus port, which allows digital sensors connections and offers power supply.

• V IN: This port is to power the datalogger. It’s designed to work in 10-30V range.

• PWR-CONFIG: This port will allow the selection of Power supply. A jumper between two rightmost connections is needed to let the datalogger be powered up.

• ANALOG INPUTS: This 8 terminal blocks is used to connect analog sensors. Starting from bottom-left to bottom-right we find channels from 1 to 12, and from top-left to top-right we find channels from 13 to 24.Every 6 connections, there is a Ground connector designed to be the termination of shielded cables.

Rear Panel

Figure 3

NI2400’s rear panel has 2 Digital Inputs and 1 Digital Output.

• Digital Inputs IN1 IN2 can be configured to read rain meters and anemometers, or similar pulse sensors (optoisolated, Min input voltage is 5V and Min current input is 2mA, while Max input voltage is 24V and Max current is 10mA, Max frequency 1KHz, accuracy 0.1Hz).

• Digital Output is a relay output (for alarms), volt-free closure (low voltage, 30V 2A).

Connecting PSU

The logger should be configured before powering it up. New datalogger are shipped already configured (as it follows) to be powered from external power source. Rightmost pins of PWR CONFIG must be short-circuited to allow the datalogger to use V-IN source. Connect V-IN to the right Power Supply Unit. Picture below shows connections.

Cabling

Overview

This chapter will explain every connection to datalogger, how to optimize connections availability and to use proper connectors to avoid unexpected behavior (malfunctions).

Power Supply

NI2400 can be supplied with 10V to 30V. In order to grant correct functioning of every connected sensor or device, and its internal circuitry, at least 2A PSU is needed. If Analog Sensors, External Modems, RS485 SmartModbus Sensors are powered from NI2400, a more powerful PSU should be used.

Warning: ALL V-OUT connections on the front panel - in the upper terminal block expose the same V-IN applied. If you apply 24V to V-IN, 24V will be exposed. Since NI2400 can work in a wide range of voltage, use has to choose the right one to power external devices connected.

Analog Channels Connection

NI2400 can handle sensors up to a total of wires of 48 Examples: 2 wires sensors: up to 24 channels 4 wires sensors: up to 12 channels 6 wires sensors: up to 8 channels

User can also mix sensors type and the datalogger will shift positions with this rule:

• 6 Wires sensors first

• 4 Wires sensors middle

• 2 Wires sensors last

With this simple rule, it will maximize connection simplicity

Here are few examples:

Open NI2400’s web server, at “Channels Configuration -> Digital Inputs” page. Select Trigger in the IN1 Input field:

Figure 17

Digital Inputs Connection

NI2400 has 2 digital inputs (on rear panel) that can be configured, independently, as “Trigger” or “Rainmeter/Anemometer”. If they are configured as Trigger, a pulse on the channel will start an acquisition of all configured channels. If they are configured as Rainmeter/Anemometer, input frequency will be measured and logged in measure log. Readable signal specifications:

• Min 5V (2mA max)

• Max 24V (10mA max)

• Max Frequency 1KHz

• Accuracy: 0.1Hz Inputs are optoisolated.

S4S5

Figure 19

Edge parameter (Up and Down) indicates if the trigger will raise voltage between poles or drop it, or if it’s a “rectangular” wave, you can choose to use rising front or falling front. Number of reading indicates how many acquisition cycles will be performed after a trigger event. In order to use Triggers the NI2400 should not go in sleep mode. Check Energy Management section to configure the datalogger to avoid switch off (by selecting Always ON). For more information about how to configure Digital Inputs, refer to Digital Inputs section.

Digital Output Connection

NI2400 is provided with a Digital Output (NC / NO), which can drive low voltage (max 30V, 2A). It’s a relay, so it is a volt-free switch. In order to handle higher voltages or currents, use internal relay to drive a rugged heavy duty relay.

RS485 SmartModbus Connection

NI2400 can read digital sensor over the RS-485 SmartModbus port. The port used for sensors connection is RS-485#1.

WARNING: RS-485#2 PORT DOES NOT WORK WITH DIGITAL SENSORS AS IT IS DESIGNED TO WORK ONLY WITH MULTIPLEXERS.

RS-485#1 port presents 5 connections:

• Data – : can be named as B or “inverting pin” or TxD-/RxD-

• Data + : can be named as A or “non inverting pin” or TxD+/RxD+

• GND: it is the reference pin. It is recommended to use GND (SC, C, or reference pin) while connecting RS-485 sensors.

• +V: NI2400 can power RS485 sensors. It provides the same power source applied to NI2400 VIN. Be careful to choose the right supply to power both datalogger and sensor.

• GND: same as +V, is the negative connection of power supply. RS-485 allows daisy chain connections. The example below shows an NI2400 datalogger with four temperature and humidity probes connected in daisy chain.

WARNING: BE CAREFUL ON CABLE DIMENSIONS, AS THEY ARE AFFECTED FROM TOTAL LENGTH AND PROBE NUMBERS. BE SURE TO CHOOSE A CABLE OF THE RIGHT SIZE FOR YOUR PROJECT.

Example

Figure 21

Not all probes have a signal GND (SC) pin, and in the example above, the probe was not connected to signal ground.

Multiplexers Connection

Figure 20

The minimum distance between two nodes (NI2400 to probe, or probe to probe) is 30 cm.

NI2400 offers Analog Sensors expandability through Multiplexers. Multiplexers are expansion boards that can read up to 24 sensors each, with connections logic similar to NI2400 (explained in Multiplexer Section), which will be connected to channel 22/23/24 of NI2400. More than one Multiplexer can be connected to NI2400, up to 16 Units, daisy chained to RS-485#2 and channels 22/23/24.

MODBUS SENSORS

What’s Modbus?

Modbus is a serial communication protocol, made by Modicon in 1979 to link their PLC. It has become a de facto standard in communication protocol, and it’s now a commonly available means of connecting industrial electronic devices. Advantages in industrial sectors are:

• developed with industrial applications in mind

• openly published and royality-free

• easy to deploy and mantain

• moves raw bits or words without placing many restriction on vendors Modbus enables communication among many devices connected to the same network, for example a system that measures temperature and humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Many of the data types are named from its use in driving relays: a single-bit physical output is called a coil, a single-bit physical input is called a discrete input or a contact.

Figure 37

• pushing on EdiT it is possible to set up all sensor parameters, as you do for a local analog

channel. The conguration of an analog channel on multiplexer is not different from that

of a local analog channel.

NOTE: once the conguration of all channels of multiplexer ended, it is advised to push on LOCK. In this way, the conguration is “blocked” and the removal of one or more sensors doesn’t modify the position of those that are cong-

ured yet.

ATTENTION: the addition of a new sensor to a multiplexer that has been already

congured could cause a change in sensors position on multiplexer channels.

In case of sensors that are physically already connected to the multiplexer, it is necessary to check that their positions are the same. If the positions changed, it is necessary to re-wire the sensors to the multiplexer.”

By clicking “Edit” (Fig.2) on the sensor row to congure, the system shows typical sensor (IPI, H-LEVEL, TILTMETER) and a SmartModbus element (Fig.3). SmartModbus is selected if the User has a generic modbus sensor.

Figure 41

Modbus Address is sensor’s modbus address, usually settable from the sensor.

Pre Measure Actions:

Some sensors require either a command or a condition to be true before actually pushing the data in the right register. Send Command enabled orders the NI2400 to push data (Value eld) in a sensor’s register

(Reg Address (hex)). You can “Force Multiple Reg” o “Write Coil”. Wait Condition enabled let the NI2400 check if Coil, Input or Holding are less, more, equal or different from a chosen Value. It allows also to wait for a certain time. Endianess allows to select if the sensor use a Little Endian or Big Endian data type.

Acquire Measures:

This section is the actual data reading from the modbus sensor. On most sensors, this is the only section the User should care of. Measure n enabled allows the NI2400 to read the register (Holding, Input or Coil) at the

specied “Reg Address (hex)”. Data Type is Signed or Unsigned Integer, Float and Fixend

Point. Register Number&Order let the User choose which register and in which order data is stored in. Usually is reported in sensor’s datasheet or instruction manual. Endianess allows to select if the sensor use a Little Endian or Big Endian data type.

Post Measure Actions:

As Pre Measure Actions, this is not always required, but some sensors need a register to be written in order to return in standby or reset. Settings are quite similar to Pre Measure Ac-

tions’ Send Command, which can be enabled or not, and actions are Force Multiple Reg, Write Coil (Register Address is specied in Reg Address (hex) eld) and Wait Time. Endianess allows to select if the sensor use a Little Endian or Big Endian data type.

Output conguration and alarms 1 & 2

This are channel related settings. The user can specify channel name, a short description, and data conversion.

Conversion:

Linear: if sensor output is linear, the systems needs to know Zero Point (Ez) and Sensibility(S)

and Number of Decimals (eld will be enabled). The output will be equal to Sx - Ez

Polynomial: if sensor output is not linear this allows the user to specify sensor output curve, and enable Zero Reading (Ez), Poly.Coeff. A, B, C and D and Number of Decimals. The output will be equal to Ax3 + Bx2 + Cx + D - Ez

Engeneering Units: to complete data with the right engeneering unit like bar,°C, °F, %HR and so on. Number of Decimals: after linear or poly conversion, here are the number of decimal digits the system will round the value at. Skipped: the system will ignore this sensor

Tips

Multiple Sensor in one single Modbus Device

Our System allows the user to connect one single Modbus device providing information coming from different sensors.

What if a sensor has more than 2 channels?

The NI2400 allows to create another sensor with the same Modbus address (Fig.9,10,11), so user can select 4 (or more, creating other sensors) registers to read data from.

Pre Measure Actions (if required) will be set only in rst sensor (relative to the Modbus slave

device) and Post Measure Actions will be set only in last sensor (always relative to the Modbus slave device)”

• Acquisition speed and precision

• IoT Enabling

Serial Number: This is the device serial number. It is composed by 8 decimal digits.

Identification: A short string (16 characters maximum) to identify the datalogger.

Identification is used for USB data export. Admitted characters are: Letters (a-z, A-Z) Numbers (0-9) Only this special characters: ._()[]-{} Non-admitted characters will be substituted with _ (underscore) character.

Measurement Settings (Standard, High Precision, Fast): These are 3 different measure configurations. User can also modify settings, these are recommended settings.

Fast Measurement: The datalogger does not execute analog autocalibration.

Relay Warmup: Delay time between relay activation and acquisition process

ADC Average Number: Number of average computed by Analog to Digital Converter

Simultaneous Relay Number: number of simultaneously activated relays

Relay time Gain: Relay excitation time (tens of milliseconds)

ADC Speed: ADC Sample rate, in SPS (Sample per Seconds)

Relay Discharge: before acquisition process, all relays are set to short circuit to discharge

capacitors.

Relay Reset: Optimization of relays movements

Turn Off Analog During Warm-up: during sensor’s warm-up, analog board is temporarily

turned off

Analog always on: Analog circuits are turned on at first acquisition cycle (in RUN) and then won’t be turned off (except when CONFIG or STOP mode are set). This allows faster acquisition rates. In Test Measure mode, analog board is turned on temporarily then turned off again. If datalogger will go in sleep mode, analog circuit should be re-initialized at next acquisition cycle.

This page is dedicated to low levels tweaks to improve stability and correct readings.

Enable VW Tracking: This option will speed up Vibrating Wire Excitation by lowering the time needed for frequencies scan.

VW Noise subtraction: It performs a noise analysis of the channel, to have a better SNR after excitation.

VW Excitation: This field enables the excitation of Vibrating Wire. If it’s disabled, no excitation will be applied while reading vibrating wire, thus making the reading impossible. It can be used to test with functions generators.

Thermocouple break check: before TC readings, NI2400 inspects TC circuitry to check total resistance. If value is out of thresholds, TC will be flagged as broken, and NAN, +FS or -FS will be recorded. If Thermocouple break check is disabled, this control won’t be executed. It is useful to disable this control when using calibrators or mV sources connected as thermocouple, since their behavior is not the same as Thermocouple’s wire.

FTP file name format: it allows choice between different file name’s formats.

ALARMS

Overview

• NI2400 can handle alarms of both channel (reading out of a determined range) and device (malfunction, wrong configuration etc.)

• Alarms can be recorded on Alarm logs and can be sent via SMS, EMAIL, FTP or activate through NI2400’s Digital Output (refer to Chapter1 for more info).

• A first configuration must be done in the Alarm Configuration page (on the web server, click on “Configuration” and “Alarms”). The following screen will be prompted. Simple steps to configure alarms:

• Select Output

• Select “Delay”

• Select “End”

Configuration

Low Battery Alarm Threshold: An alarm will be triggered if V IN voltage drops below this threshold.

IOT Configuration IOT Enable: This checkbox, enables the communication with Exosite cloud. Read dedicat-

ed chapter for more info.

WARNING: BEWARE OF ENABLING THIS FIELD. BEFORE ENABLING THIS FIELD, BE SURE TO DELETE ALL MEASURE LOG PRESENT IN MEMORY. IF MEMORY IS NOT CLEAR, AT THE FIRST ACQUISITION, THE DATALOGGER WILL PROCESS EXISTING DATA AND TRY TO EXPORT TO EXOSITE CLOUD. USUALLY THIS OPERATION REQUIRES FEW HOURS AND THE DATALOGGER WILL BE STRUCK PROCESSING THIS DATA FOR NECESSARY TIME. IOT Cik: This field is dedicated to the CIK field, gathered from Exosite cloud after the cre-

ation of a device. Read dedicated chapter for more info.

• Send email will send an email (if RS323 modem OR Ethernet connection with internet is connected) with the Alarm, to specified recipient (see next section)

• Upload on FTP will upload the Alarm Log’s row (if RS232 modem OR Ethernet connection with internet is connected) with the alarm triggered

• Enable Digital Output will trigger the backpanel’s terminal block to control an external Alarm system

• Frequency increase will increase acquisition frequency to gather more information about the event that has triggered the alarm. Acquisition Frequency is set at 1 minute when the channel is in ALARM. If the datalogger is configured to read different sensors, and more than one sensor is in alarm, reading frequency will probably be lower.

There are pretty much the same options in the “NI2400” Section, except for Frequency increase. Event Nr. Dropdown menu will let you choose the number of events in alarm at which the datalogger triggers the alarm. 1 means at the first occurrence, 2 will skip first value in alarm, and if it still in alarm during next acquisition the alarm will be triggered, otherwise there will be no alarm event. End Dropdown menu will let you choose the number of events after which the datalogger will cease to trigger. NEVER is the option to disable this feature, and let the datalogger trigger EVERY set alarm. After configuration, click Save to proceed. If you selected SMS, email or FTP, the relative configuration option will be activated.

This page will let you select SMS recipient for triggered alarms. Number: the recipient(s) of the SMS Sensor Alarm: if you have selected SMS in sensors alarms this will let you use the current recipient for the sensor alarm NI2400 alarm: if you have selected SMS in NI2400 alarm this will let you use the current recipient for the datalogger’s alarm Add Measure in alarm: it will attach measure value to the SMS.

Channel Alarm Types

Thresholds in NI2400 alarm settings are here described. WARNING: all alarms evaluations are computed AFTER linear or polynomial conversion, if any.

Low and High Thresholds

Thresholds are basically limits to sensor’s ranges. If a threshold is overcome (lower value so low threshold, or higher value so high threshold), the alarm is triggered.

Derivate

Derivate alarm will analyze, at n sample, value of n-1 sample and compare to n sample. If value(n)-value(n-1)>threshold, an alarm is triggered.

The NI2400, with this conguration, in case it receives a positive voltage on digiTAl inpuT in1, does 5 consecutive acquisitions of all congured channels.

A practical example of the use of trigger function is that of associate NI2400 to a Seismic Station. The majority of Seismic Stations has the possibility, in case of a seismic event, to activated a digital output (an output voltage). If this signal is connected directly to the digi tal input IN1 of the NI2400, when a seismic event happens the Seismic Station furnishes a digital output on the digital input of the NI2400. The NI2400 starts to acquire all connected sensors to verify the monitoring area after the event.

VIRTUAL CHANNELS

Overview

This chapter is focused on Virtual Channels (VC from now on), to understand why VC are implemented on OM datalogger and how to configure them.

1. Why are Virtual Channels implemented in OM Family? – This paragraph shows benefits of Virtual Channels

2. Scripts – Scripts are a fundamental section of Virtual Channels’ architecture.

3. Virtual Channels configuration – “HOW TO” use and configure Virtual Channels’ with analog and digital sensors, digital input and multiplexers.

4. Common Errors – Here are shown common errors made during virtual channels creation, and how to avoid them.

Why are Virtual Channels Implemented?

We usually use sensors to get a measure. Anyway, we could need a way to modify that number because we need either a derived measure (airflow/airspeed) or an expression cal-

culated on more than 1 sensor (dewpoint or Δt between two zones for instance). We can

calculate this with spreadsheet or just let our datalogger do the work. OM Family has this feature with Virtual Channels. Virtual Cannels allows operations to be made on a single channel or between channels. OM group them into Scripts, with a maximum of 5 scripts containing 16 virtual channels each. Each Virtual Channel can handle up to 9 elements (including Virtual Channel beloning to the same script).

an: selects an analog channel (prompts a dialog box to input channel number) dig: selects a digital channel (prompts a dialog box to input channel number) mux: selects multiplexer position (prompts two dialog boxes, the 1st for channel number, the 2nd for mux address) cv: selects a virtual channel (only those included in the same script, prompts a dialog box for CV number) Apart from this we have mathematics operations, like +, -, *, /, sin, cos, tan, pi-value. Logical operations allow operations between alarms states. Every channel (analog, digital, virtual and mux) provides a checkbox in alarm configuration, VC Alarm with Logical Operations. This enables alarms to be handled by virtual channels.

The following Virtual Channel will trigger an alarm only if one of the two channels is in alarm.

MODBUS TCP (SCADA INTEGRATION)

Overview

Modbus ADU (application data unit) is sent in form of TCP packets. All Modbus TCP ADU are sent via TCP to registered port 502. Modbus over TCP allows NI2400 integration in LabVIEW and SCADA systems. By reading holding registers, it’s possible to gather all sensors data (analog, smartmodbus, multiplexers, digital inputs), events and alarm, datalogger status and information.

• It’s possible to read sensor’s alarm status.

• By integrating NI2400 in a SCADA, industrial plant remote monitoring and logging are possible without the need on-site visits.

• Maintenance costs are reduced through centralized control and monitoring to minimize downtime.

• Centralized alarms to improve operational effectiveness.

• Data could be available in mobility (depending on used SCADA).

Communication Bus

Communication bus for this module is Ethernet interface. Port used for TCP communication is 502 (Modbus TCP Standard Port) Modbus function to use for registry reading is ReadHoldingRegister.

Measure Register

For each sensor (analogs, digitals, multiplexers and virtual channels), 16 registers will be exported. Input A’s last acquired measure (Offset 0-1), input b (Offset 2-3), sensor’s temperature (Offset 4-5), Acquisition’s timestamp (Offset 6-7-8-9-10-11-12-13-14) and different flags to show acquisition status and alarm status (Offset 15). Measures will be communicated in float IEEE754 standard. Endialess can be user configured by writing 0-1-2-3 values into configuration register at 0x5000 address.

Following table will represent 4 endianless configurations: IEEE754 = AA:BB:CC:DD AA = MSB DD = LSB Configuration=0 (default)

Timestamp details

Timestamp is composed by 9 registers, with offset 6 (MSB) to 15 (LSB). Timestamp is an ASCII string 18 bytes long, in the following format: “dd/mm/yy hh:mm:ss”

Sensor Acquired

This register is set to 1 when sensor is acquired and a new data is available. SCADA (or Modbus Master) reads the updated register and reset it to 0 by using Coils Functions. In this way the system is ready to note the presence of a new acquisition. This BIT is also accessible through read/write coils functions. Coils are mapped on flag “Sensor Acquired” having referral to base address of each sensor. To obtain Coil address of a sensor, Use the following formula: Coil Address = Base Address/10 Base Address computation will be shown in next pages.

Example 1

Channel: CH4 Base Address: 30 Coil Address: 3

Example 2

General

All this registers are read-only. Only “Sensor Acquired” BIT is read-write, using Write single/multiple coils.

1. Verify that you installed the last version of rmware

2. Verify that you have an adequate power supply (from photovoltaic module or external power supply) on the V IN clamp of the NI2400; check if the voltage is within the range accepted by the NI2400 and stable.

IF THE NI2400 DOESN’T TURN ON.

Follow this step, testing after each:

1. remove power supply on V IN clamp for 10 seconds and try to reconnect.

2. verify the presence of jumper cables on the “PWR CONFIG” clamp

3. control that the power supply system works, is correctly sized and respects the characteristic declared on datasheet

4. make sure you hadn’t set the NI2400 in Timed mode using the webpage “Energy management”

NOTE: if on the display appears TELNET MODE, contact directly NEXT Industries Assistancetechnical support for assistance.

Follow this step, testing after each:

1. remove the power supply on V IN clamp for 10 seconds and try to reconnect.

2. reboot the PC and try to connect

3. make sure you congured appropriately the network card of the PC, that is it is part of the same subnet mask of the NI2400.

4. make sure you are using the correct LAN cable according to the type of network you chose.

5. make sure the NI2400 is not congured in “Timed”. In this case the network card remains switched off. It is necessary to turn it on manually from SYS menu.

6. make sure the NI2400 is not used by another user. The NI2400 accepts only one connection at a time.

7. make sure that the last user that logged on the NI2400 had logged out. Otherwise, it is

necessary to wait until the automatic log out. This happens after the time congured in

page “Energy management” has passed. You could also reboot the NI2400, in order to not wait for the log out.

8. in case of use of remote communication devices (ex: HSPA router connected to the NI2400), remove them and do a test of direct connection between PC and the NI2400. This is necessary in order to exclude problems with communication interfaces.

Follow this step, testing after each::

1. verify that the NI2400 is not acquiring. In this case, wait until the end of the acquisition or go in “DL” menu and select “Stop DL”

IT IS NOT POSSIBLE TO DOWNLOAD DATA ON USB FLASH-DRIVE

This paragraph provides NI2400 e-mail sending troubleshooting tips.

THE E-MAIL TRANSMISSION INVOLVES DIFFERENT DEVICES. IN THIS DOCUMENT, WE TRY TO DETERMINE WHICH DEVICE COULD CAUSE THE PROBLEM AND THEN WE TRY TO SOLVE IT.

The “system” is composed as follows:

1. NI2400

2. Internet Service Provider (ISP): allows the communication between NI2400 and the email server

3. E-mail Server (ESP): allows to send and to receive e-mails

IF THE NI2400 DOESN’T SEND ANY E-MAIL ALTHOUGH IT IS CONFIGURED.

Follow this step, testing after each:

1. verify the events log and refer to manual “Codes Alarms-Events” to understand eventual logs

2. verify that the SIM is properly inserted in its slot into the communication device (HSPA

router or 2G modem) or that your network devices are properly congured to permit the e-mail sending (rewall, port, etc)

3. verify that you inserted your SMTP server account correctly (“SMTP Server Conguration” page)

4. verify that the SMTP account is a simple authentication. The NI2400 doesn’t support SSL.

5. If you use a communication device base on mobile network, verify that there is a mobile coverage (according to the adopted technology e.g: 2G, 3G or 4G) on the site where the NI2400 is installed.

6. If you use a 2G (GSM/GPRS) modem, verify that there is a good 2G signal where the NI2400 is installed. In some place there is only a 3G or 4G coverage. 2G modem is not compatible with 3G, 4G and CDMA networks.

NOTE: it may be that the ISP (Telecom, Vodafone, AT&T, Verizon, etc.) doesn’t

coincide with the ESP (Gmail, AOL, etc.)

Resolution

FIRST OF ALL, INSURE WITH YOUR IPSP THAT:

1. The SIM card or your network is enabled to the internet

2. The e-mail transmission is allowed on the used APN or on the used network

SECONDLY, INSURE WITH YOUR ESP THAT:

1. there are no momentary breakdowns on ESP server

2. the username and password of your e-mail account are valid and accepted

3. that the e-mail account you want to use is active

2. Verify that you have the correct power supply (from photovoltaic module or external power supply) on the V IN clamp of the NI2400

THIS PARAGRAPH PROVIDES FTP SERVER SENDING DATA TROUBLESHOOTING TIPS.

The FTP transmission involves different devices. In this document, we try to determine which device could cause the problem and then we try to solve it.

The “System” is composed as follows:

1. NI2400

2. Internet Service Provider (ISP): allows the communication between the NI2400 and FTP server

3. server FTP: physical space in which it is possible to memorize les

Follow this step, testing after each:

1. verify the events log and refer to manual “Codes Alarms-Events” to understand the possible logs

2. if you use a HSPA router or 2G modem verify that the SIM card is properly inserted in its slot.

3. verify that you have inserted your FTP server account correctly (“Measure log data transfer” page)

4. verify that the FTP server is a basic authentication FTP (for example not MD5, KERBEROS etc.) and that doesn’t utilize any secure layer (for example SSH/SSL, FTPS/SFTP etc.). The NI2400 does not support secure layer and encrypted authentication (encrypted username and password).

5. if you use a mobile device, verify that there is a good coverage on the site were the NI2400 is installed.

6. if you use 2G (GSM/GPRS) modem, verify that there is a good 2G (GSM/GPRS) signal on the site were the NI2400 is installed. In some place there is only a 3G or 4G coverage. 2G modem is not compatible with 3G, 4G and CDMA networks .

MEASURE

NOTE: the FTP server could be completely transferred to societies that oer an

hosting FTP service. It could also be internal. In this second case, you have to ask for information to your IT manager.

FIRST OF ALL, INSURE WITH YOUR ISP THAT:

1. The SIM card or your network is enabled to the internet trafc through APN

2. The data transmission on FTP server is allowed on the used APN or on the used network

INSURE WITH YOUR SYSTEM ADMINISTRATOR OR WITH THE SOCIETY THAT SUPPLIES THE HOSTING FTP SERVICE THAT:

1. there are no momentary breakdowns on FTP server

2. the username and password of FTP account are valid and accepted

3. the FTP account and the same FTP server that will be used are active

THESE POINTS DO NOT DEPEND ON NEXT INDUSTRIES AND NEED TO BE RESOLVED THROUGH YOUR ISP OR ESP

If you don’t have any problem with the ISP and the FTP server, you could proceed looking for causes on the NI2400.

IF THE NI2400 DOESN’T SEND ANY DATA ON FTP SERVER ALSO IF CONFIGURED.

Number of Inputs: 24 differential analog inputs, individually configured. Channel expansion provided by multiplexers. There are 8 terminal blocks (each terminal block can handle up to 3 sensors). NI2400 is designed to work with 2 to 6-wire sensors. You can connect 2-wire sensors on each channel and read 24 sensors, or 4-wire sensor and read 12 channels. The system will order sensors depending on how many wires they use, placing 6 wires sensors first, 4 wires in the middle, and 2 wires last. Once software configuration is done, a click on “Wiring scheme” button on the web interface near the sensors will show how to physically connect the chosen sensor to the block. It shows “relative” position, so if you start connecting sensors from the first you will not have to leave “unused” positions (except for the ground connection of every block, if not used).
