PLC & HMI programming
A machine needs a control program and operator screens that match how the line actually runs, with the sequence documented and tested before it reaches the shop floor. I write the commented PLC program and HMI screens, hand over the I/O and tag list and a sequence description with an offline test report, and support commissioning on site around Coimbatore.
