Process Automation Training | PLC SCADA Training

Processing based industries recruit engineers for their Operations and Maintenance based requirements and they will naturally look for the engineers who have the right aptitude, knowledge and skills in the area of Process Automation related field. All the petro-chemical industries, refineries, pharmaceuticals, chemical industries, etc., thus need engineers who have knowledge and skills in the relevant field. Scope for engineering personnel therefore is high with the expanding industrial landscape involved in Process Automation Training in chennai. Process Automation Control Training – covering PLC & SCADA systems, is also very essential, especially for industries processing inflammable fuels, hazardous & toxic chemicals which will result in a serious life risk related mishaps if controls are absent or if they do not properly made to operate with zero defects.

PLC Programming

PLC Training : PLC programs are typically written in a special application on a personal computer, then downloaded by a direct-connection cable or over a network to the PLC. The program is stored in the PLC either in battery-backed-up RAM or some other non-volatile flash memory. Often, a single PLC can be programmed to replace thousands of relays.[7]


Under the IEC 61131-3 standard, PLCs can be programmed using standards-based programming languages. A graphical programming notation called Sequential Function Charts is available on certain programmable controllers. Initially most PLCs utilized Ladder Logic Diagram Programming, a model which emulated electromechanical control panel devices (such as the contact and coils of relays) which PLCs replaced. This model remains common today.
IEC 61131-3 currently defines five programming languages for programmable control systems: function block diagram (FBD), ladder diagram (LD), structured text (ST; similar to the Pascal programming language), instruction list (IL; similar to assembly language) and sequential function chart (SFC).[8] These techniques emphasize logical organization of operations.[7]
While the fundamental concepts of PLC programming are common to all manufacturers, differences in I/O addressing, memory organization and instruction sets mean that PLC programs are never perfectly interchangeable between different makers. Even within the same product line of a single manufacturer, different models may not be directly compatible.
