Siemens PLC Technician – SPT
What is Siemens PLC Programming?
PLC stands for Programmable Logic Controller. It is an industrial microprocessor based control system used to automate machines and processes in factories and plants. Siemens PLC programming is the process of creating structured control logic using Siemens automation software to control industrial machines and processes.
Siemens PLC systems are widely used in: Mining plants, Manufacturing industries, Water treatment systems, Food and beverage processing, Power plants, Oil and gas facilities.
Who needs this training?
This training is designed for fresh graduates in Electrical and Electronic Engineering, instrumentation technicians, industrial electricians, automation engineers, maintenance engineers, plant supervisors, and engineering students.
