4351B Dual power supply module

4351B has restrictions on the total number of system points and the number of expansion modules, when the expansion still cannot meet the requirements, the network structure can be used. Individual commands of some manufacturers’ products do not support expansion modules, therefore, it is necessary to pay attention to the software compilation when adopting analogue modules such as temperature, etc. Each manufacturer also has some regulations, please see the relevant technical manual. There are many types of expansion modules available from various companies, such as single-input modules, single-output modules input-output modules, temperature modules, and high-speed input modules.

When 4351B carries out network design, it is much more difficult than PLC stand-alone control Firstly, you should choose a model that you are more familiar with, and you should have a deeper understanding of its basic and functional instructions, and you should also have a careful understanding of the execution speed of the instructions and the storage capacity of the user programme. Otherwise, it cannot adapt to your real-time requirements and cause system crash. In addition, the communication interface, communication protocol data transfer speed should also be considered.

4351B in the preparation of software, you should first familiarise yourself with the software manual of the selected PLC product, to be skilled before programming. If the graphical programmer or software package programming, it can be directly programmed, if programmed with a handheld programmer, you should first draw a ladder diagram, and then programming, so that less error, speed is also fast after the end of the programming first air-conditioning programme, to be normal after each action, and then debugging on the equipment.
