The installation mode of PLC system is divided into centralized, remote I/O and distributed with multiple PLCs connected.

The centralized type does not need to set up remote I/O hardware to drive, and the system has fast response and low cost; The remote I/O type is applicable to large systems, and the devices of the system are widely distributed. The remote I/O can be installed in the vicinity of the on-site devices, with short connection, but the driver and remote I/O power supply need to be added; The distributed networking of multiple PLCs is applicable to the situation where multiple devices are controlled independently and connected with each other. Small PLCs can be selected, but communication modules must be attached.

Corresponding functional requirements

Generally, small (low level) PLC has logic operation, timing, counting and other functions, which can be satisfied for equipment that only needs switch control.

For the system with switch control as the main control and a small amount of analog control, the enhanced low-grade PLC with A/D and D/A conversion units, plus and minus arithmetic operation and data transmission functions can be selected.

For complex control, it is required to realize PID calculation, closed-loop control, communication networking and other functions. Depending on the size and complexity of the control, medium or high-end PLC is selected. However, the price of medium and high grade PLC is relatively expensive, and it is generally used in large-scale process control and distributed control systems.

Response speed requirements

PLC is a general controller designed for industrial automation. The response speed of different grades of PLC can generally meet the needs of its application range. If the PLC is to be used across the range, or some functions or signals have special speed requirements, the response speed of the PLC should be carefully considered. The PLC with high-speed I/O processing function or the PLC with fast response module and interrupt input module can be selected.
