Omron PLC is a compact PLC with perfect functions, which can provide high value-added machine control for industry-leading conveying and decentralized control; It also has the ability to upgrade through a variety of advanced built-in boards, large program capacity and memory units, and efficient software development in the Windows environment.
1. Selection of PLC memory type and capacity
The memory used in the PLC system is basically composed of three types: PROM, E-PROM and PAM, and the storage capacity is changed according to the size of the random device, the maximum storage of the general small machine can be less than 6kB, the maximum storage of the medium machine can reach 64kB, and the maximum memory of the large machine can be up to megabytes. When using, you can choose the appropriate model according to the storage needs of the program and data, and if necessary, you can also specially expand the memory design.
Second, the consideration of economy, when selecting PLC, the performance-to-price ratio should be considered. When considering economy, we should consider the scalability, operability, input-output ratio and other factors used together, compare them, and finally select a more satisfactory product. The number of input and output points has a direct impact on the price. Each additional I/O card requires a certain fee. When the number of points is added to a certain value, the corresponding memory capacity, rack, motherboard, etc. must also be added accordingly, so the addition of points has an impact on the selection of CPU, memory capacity, and the scale of control functions. Full consideration should be given to the budget and selection, so that the entire control system has a more reasonable performance-to-price ratio.
