1. Storage capacity
Storage capacity refers to the capacity of user program memory. The user program memory has a large capacity and can be used to program complex programs. Generally speaking, the user memory capacity of a small PLC is several thousand words, while the user memory capacity of a mainframe is tens of thousands of words.
2. I/O points
The number of input/output (I/O) points is the sum of input and output signals that the PLC can accept, and is an important indicator to measure the performance of the PLC. The more I/O points, the more external input and output devices can be connected, and the larger the control scale.
3. Scanning speed
Scanning speed refers to the speed at which a PLC executes user programs and is an important indicator of PLC performance. The scanning speed is generally measured by the time required to scan a 1K word user program, usually in ms/K words. The PLC user manual generally provides the time taken to execute each instruction, and the speed of scanning can be measured by comparing the time taken by various PLCs to perform the same operation.
4. Function and quantity of instructions
The strength and quantity of instruction functions are also important indicators for measuring PLC performance. The stronger the functionality and quantity of programming instructions, the stronger the processing and control capabilities of PLC, and the simpler and more convenient user programming, making it easier to complete complex control tasks.
5. Types and quantities of internal components
When programming PLC, a large number of internal components are needed to store variables, intermediate results, hold data, timed counts, module settings, and various flag bits. The more types and quantities of these components, the stronger the PLC’s ability to store and process various information.
6. Special functional units
The number of types of special functional units and the strength of their functions are important indicators for measuring PLC products. In recent years, various PLC manufacturers have attached great importance to the development of special functional units. The types of special functional units are increasing and their functions are becoming stronger, leading to the expansion of PLC control functions
7. Scalability
The scalability of PLC includes the expansion of I/O points, storage capacity, networking functions, and various functional modules. When choosing a PLC, it is often necessary to consider its scalability.
