Modbus RTU

Local Monitoring
Modbus RTU is an electronic device which can be connected with any field instrument such as electrical energy meters, water flow meters, gas meters, fuel meters to monitoring and storing the data directly into the computer. The MODBUS RTU is connected with the field instrument through RS485 or MODBUS Protocol and its connected with the PC with RS232 cable. This is local level monitoring of data where field instrument and the Modbus RTU are installed.

GPRS/GSM Enabled Wireless Remote Monitoring
In case the MODBUS RTU is fitted with a GPRS/GSM circuit & SIM then the data of field instrument can be monitored remotely on a central control room PC. This is call Online Wireless Remote monitoring of field instruments. You need a web interface configured to receive data from the central server and to display it live.

Data can be stored on the remote server also to generate daily reports for review and analysis.

You can connect one MODBUS RTU with each field instrument/device from which data is to be monitored and stored on remote & central server. Data of all the remote devices/instruments can be monitored on one interface or in one account or multipe individual accounts. Just click upon the remote device ID and data is displayed i tabular form. This data is refreshed every one minute. You can also see live graphical trends of the data, excel reports. This is wireless remote monitoring of data where field instrument and Modbus RTU are installe at remote location and date is being received at remote central server room for global access of device data.

The Modbus RTU can be used to monitor energy meters, water flow meters, gas meters, temperature, humidity, pressure, water quality, visitor counter, solar VFDs, solar Inverters, liquid dispensers, weighing machines. Technically any device or field instrument with RS485 communication port can be connected with this Modbus RTU. As this Modbus RTU is GPRS/GSM enabled so you can monitor the data remotely from anywhere in the world. We provide you a web interface and and your unique login details to monitor the data.


Monitor Remote Instruments
You need to connect your remote instruments or devices having a RS485 com-port with the Modbus RTU. Instert a GPRS enabled 2G/3G/4G SIM card in the SIM slot. Connect Modbus RTU with a 12VDC @ 2A. DC supply to Modbus RTU must be off while inserting or removing the SIM. Red LED glows if the DC supply is OK. The Modbus RTU takes 3 - 5 minutes time to initialize and to connect to our New Delhi based central server. Initializtion time of Modbus RTU depends upon the network signals. You can connect energy meters, MF meters, water flow meter, gas meter, solar VFD, solar Inverter, temperature sensors, pressure sensors, water quality sensors, vibration sensors. Take care the field device/instruments/meter must have a RS485 com-port to connect with the Modbus RTU. Once the connectivity with the central server is made and the field instrument/device is working OK, the Modbus RTU start sending data strings to central server at every 60 second interval.

Central Server
Softbit has installed a public secured central server at New Delhi with dedicated internet broadbad lines. This server works around the clock to receivce data strings from all around the globe and store the data in the data bases for report generation, review and analysis later on. Live data is also made available to users from this central server.

In case user is interested to direct the field data from devices and instruments to their own dedicated server then they need to install their own private server with  server application compatible with our Modbus RTU. We can provide the data string protocols if required.

Web Interface - Online Live Data
We have developed a web interface for Wireless Remote Data monitoring through Modbus RTU. Every client/user gets personal login credentials to login into his/her online web account. All the units ne/she buys are allotted to his/her personal account. This enables him/her to access live data of all the remotely installed devices in one account. Just click upon the specific remote device ID and you e can see the live data in tabular form. You can see the location of the remote unit is your SIM card service provider has enebled the SIM with location co ordinates data. You can also view live graphical trends. Generate daily reports in MS Excel.

So this is how the Wireless Remote Monitoring System works using a Modbus RTU.

We design and develop customizes remote monitoring systems as per client requirements and specifications. Our GPRS/GSM enabled Wireless Remote Monitoring RTUs find applicatios in Solar Water Pump Monitoring, Energy Monitoring, Water Flow Monitoring, Remote Water Management, Temperature Monitoring, Pressure Monitoring, Water Quality Monitoring like pH value monitoring, Machine Vibration Monitoring, Sound Level Monitoring. Wireless Modbus RTUs are designed and developed in house by Softbit Team. 

We also manufacture GPRS/GSM RTUs with built in memory slot. You can insert a SD card for storing the data on memory card. This will help you to get all data in case there is a network issue because data is being saved on the memory card continuously. You can download the data on a SIM card reader easily. At sensitive locations where maintain a data record a necessity this SD card slot is very helpful.  Solar water pump suppliers, power distribution companies etc.,.  are now a days going for this facility for storing the data on local level in the RTU. You can use 36GB or more SD card for data storage. Wireless Modbus RTUs are manufactured by Softbit Team.

We at Softbit are capable of designing Wireless Modbus RTUs  as per your specifications. Just share your technical details and application and we will come up with a Wireless Modbus RTU.
