Industries in India have been directed to install CMS Devices from last more than 10 years and many of these industries have installed such systems.
Instruments required for Continuous Monitoring Systems (CMS) are mostly manufactured in different foreign countries.
Two types of Output signals from these Instruments installed in industries are available Digital outputs and Analog outputs.
CMS Systems
Data use till date
Da ta S

Industries had connected these CMS instrument’s output to their control rooms through PLC (Programmable Logic Controllers) to check on emission/effluent levels (Every process-wise, parameter-wise Limits are already prescribed by SPCBs/CPCB) to check the performance of plant and if required have changed the combustion element ratios.

1. To Install CEMS Parameter Specific Effluent and Emission Monitoring Systems. 2. To connect and upload online data at SPCBs/PCCs & CPCB server in a time bound manner. 3. Industries have to ensure regular maintenance and operation of the online systems with tamper proof mechanism having facilities for online calibrations.
Hence, to manage these systems and provide information as mandated has become a real challenge.

Effluent: (08 ) pH, BOD, COD, TSS, Cr, As, NH3, Aox
*Parameters to be monitored are industry specific.
How to get these systems connected in the network?
Da ta S
ubmis s ion
Old Instruments with Analog Technology …….. Can not be calibrated online, hence to be replaced with New Instruments.
Old Instruments with Digital Technology …….. Capable of online calibration need to be connected.
New Systems …. Have to have compatibility of online calibration than a procedure has to be defined so that these new systems gets immediately integrated into the network.
New Systems

The advanced CMS system are providing digital output.
These advanced CMS systems not only provide the parametric value but also provide information about system. This includes Diagnostics features such as lamp voltage, frequency of operated chopper, cooling temperature of Photomultiplier tube, vacuum inside reaction chamber and many more which provides information about health of instruments.
Beside diagnostics, advancements in the technologies have provided us a capacity to monitor the Instruments kept at a remote location and to configure and calibrate theses instruments with a click of button remotely.

Data Transmission
Da ta T
rans mis s ion
Exchange of information between two devices.
For exchange of Data to occur communication devices
must be a part of system made up of hardware and
software.
Exchange can occur on some form of Media like
internet or wire.
Types of Data Transmission
Da ta T
rans mis s ion
– Parallel –all the bits of data transmitted simultaneously on separate communication lines.• Fit for shorter distances like printer connection.• High speed
– Serial…..fit for long distance data transmission
• Synchronous –bits transmitted in a line one after another-- requires one communication line with start & stop bits.
Example are: PS2 Mouse or Keyboard • Asynchronous—sends one word at a time with start and
stop bit.Example is : RS 232 Simple terminal serial communication

Components of Data Communication
Receiver: It is the device which receives the data.
Sender: It is the device which sends the data.
Message: Information being transmitted text files, audio, video etc.
Medium: It is the physical path by which the a
message travels from sender to receiver.
Protocol: It is set of rules that governs the data communication.
Protocol’s functionality
Da ta T
rans mis s ion
A protocol is a set of rules which governs the transfer of data between computers. Protocols allow communication between computers and networks.
Handshaking is used to establish which protocols to use. Handshaking controls the flow of data between computers
Protocols will determine the speed of transmission, error checking method, size of bytes, and whether synchronous or asynchronous
Protocols exist at several levels in a telecommunication connection. For example, there are protocols for the data interchange at the hardware device level & at the application program level. Protocols are often described in an industry or international standard.
Layers of OSI model
Open Systems Interconnection In the standard model known as Open Systems Interconnection (OSI), there are one or more protocols at each layer in the telecommunication exchange that both ends of the exchange must recognize and observe

Data File is divided into 4 groups-
1. The Identification Group –Name, Address of the industry, etc.
2. The Description Group – Parameters information, no of sites, no. of parameters, Units used, Sampling Height, Lat and Long coordinates, Upper and Lower limits etc.
3. The Data Group – All about the Data Generated e.g. parameter code, site code, data duration, sampling time, samples per time interval, multiplication factors, etc.
4. The comments Group – Comments providing additional information
Protocol in Nut Shell
Suppli er s of C
MS
A procedure through which :1. Hardware devices recognize each other2. Devices understand the encryption & decryption of
data3. Devices verify the data4. System recognizes the data sent and data received5. Set of data for specific parameter like Data +
Diagnostics data+ calibration data+ configuration data
6. Set of data recognizing stations, channels, and various other details
7. Set of commands which shall provide the control to run calibration and configurations etc.
