CURRICULUM
Day One
- Relay Logic and Diagram. Conventional ladder diagram: power ladder and control ladder diagram. Design examples: self-latching, box sorting system, forward-reverse three-phase induction motor etc
- Memory map. Sensors and output devices. Sinking-sourcing concept. Input/output lines. Instruction set command: input instructions, output instructions, control instructions and timer/counter instructions
- data comparison instructions, data movement instructions, increment/decrement instructions, logic instructions, high-speed counter control instructions, expansion functions and special system instructions.
- conversion from conventional ladder diagram to PLC ladder format.
Day Two
- applications of input/output units, timers, internal relay, looping and branching
- application of counters, differentiate up/down, and latching
- applications of reversible counters, auxiliary relays (AR), special relays (SR) and expansion functions.
- circuit protections, power handling limitation, cabling, sensors, switches, push button, colour sensors, relays, single-phase AC motor, three-phase AC motor (DOL), DC motor and light indicators.
