9. Each input/output contact of PLC is referred to as a micro PLC with a number of I/O points less than 64 points, a small PLC with I/O points at 64-256 points, a medium-sized PLC with I/O points at 256-1024 points, and a large PLC with I/O points above 1024 points
Depending on the complexity of the industrial control system, the functions of the required PLC are also different
Low-grade machine: only switch operation, logic operation, timing and counting
Mid-range machine: with switching and analog control, digital operation, interrupt control and communication functions
High-end machine: with switching and analog control, matrix operation, data management, communication networking and other functions
