Common PLC modules are.

Power Modules

Provides internal power to the PLC, and some power modules can also provide power to the input signals.

I/O module

Is the input / output module module, I represents the input, o represents the output. i / o modules can be divided into discrete modules, emulation modules and special modules. These modules can be mounted on rails or racks with multiple slots, and each module is inserted into one of the slots depending on the number of points.

Memory modules

Mainly storing user programs, some memory modules can also provide auxiliary working memory for the system. Structurally, all memory modules are connected to the CPU module.

Baseboard, rack modules

As the name implies, in the installation of various PLC modules, the baseboard and rack modules act as the baseboard, providing the bus for communication between modules. Some connections between multiple baseboards use interface modules, and some use bus interfaces. It varies from manufacturer to manufacturer, but PLCs vary by type.

The specifications of the main chassis of a box-type small PLC vary depending on the number of I/O points that can be provided by grouping the above modules in one chassis. Box-type PLCs do not contain a CPU, and also have an I/O expansion box that is used only as a power supply and I/O unit. The specifications of the expansion box vary depending on the number of I/O points.

In addition to the above modules, PLCs have special intelligent or functional modules. For example, A/D (model) module, D/A (model) module, high-speed counting module, position control module, temperature module, etc. These modules have their own CPUs, and by pre-processing or post-processing the signals, they can simplify the control of the PLC CPU and simplify the amount of complex program control.

The types and characteristics of intelligent modules also vary greatly. PLCs with excellent performance have a wide variety of types and excellent performance.

Communication modules connected to PLCs can communicate between PLCs and computers, between PLCs and PLCs, with other control units such as inverters and temperature controllers, and also form local area networks. The communication module indicates the network function of the PLC and indicates an important aspect of the current PLC performance.
