What are the attributes and characteristics that differentiate the DCS system from the PLC. The topic has remained under debate for long, and especially today when we have already entered into new era of Hybrid Distributed Control Systems, it is not an easy task to select and differentiate the advantages and drawbacks one can get from different systems for the intended application. Let us first roll back to the history of DCS and PLC. Process plants used to have long series of panel mounted Single Loop Controllers (PID controllers). In Single loop controllers, the control was non-centric and distributed. In early 80s, manufacturers came up with an idea of integrating all the PID controllers to a central digital system still maintaining the ...

Flow Rate Equations are provided here for general use which are in accordance with: American Gas Association Report 3 American Gas Association Report 5 American Gas Association Report 8 American Petroleum Institute API MPMS 14.3.1 Following equations can be used for Mass Flow Rate, Volumetric Gross Flow Rate, Volumetric Net Flow Rate and Energy Flow Rate 1.  Mass Flow Rate at Flowing Conditions ‘Qm’ (Klbm/hr) Q =(C x EV x Y x  ∏/4 x d2 x sqrt(2 x ΔP x Pf) ) x 3600/ 1000   2.  Volumetric Gross Flow Rate at Flowing Conditions ‘Qv’ (MCF/hr) Qv =  Qm / ρf 3.  Volumetric Net Flow Rate at Base Conditions ‘Qb’ (MSCF/hr) Qb =  Qm / ρb 4. Energy Flow Rate at Base Conditions ‘Qe’ (MMBTU/hr) Qe = ( Qb x HV ) / 1000   Nome...

Whether to migrate to new process control system and decommission the existing one; is a question asked by many plant owners. It is not only a matter of cost but lot of human resources and time is required to accomplish this successfully. Migrating to a new platform whether it is same OEM/vendor or new, is a question to be answered by the persons working for the plant. If this question is asked to vendors/sellers, then no one answer would be obtained.  New seller would provide arguments in the favor of new platform.  He will first focus on the disadvantages of the existing system and may argue following in favor of the migration. Parts will eventually become obsolete and not supported by the OEM. Degrading parts of the system will tend...

Networking and Internet security has become an important issue in the Industry Automation. This blog takes three very basic terminologies which are used by us in routine. Socket A socket is the endpoint of a connection over a TCP/IP network, much like a phone is the endpoint of a connection in the telephone network. A socket is the combination of a TCP port and an IP address. Ports are logical interfaces for applications, and they are assigned numbers. For example, The Web’s HTTP protocol is located at port 80. Using the telephone analogy, the TCP port is then like a telephone number and the IP address is the location of the phone. A socket is like a phone that has been assigned a phone number. However, a typical host can have many socke...
