P0926GH does not need to be expanded, when the system is larger, it has to be expanded. Products of different companies, the total number of points of the system and the number of expansion modules are limited, when the expansion still can not 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 from various companies, such as single input module, single output module input output module, temperature module, high-speed input module, etc..

P0926GH Before programming the software, you should first familiarise yourself with the software manual of the PLC product you have chosen, and then program it after you have become proficient. If the graphic 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 in the device.P0924JH do not need to expand, when the system is larger, it is necessary to expand.
