The I/O points of CP461-50 system are about 120, and the DI and DO points are basically equal. In order to solve the above problems, we adopt the 214 CPU module of Siemens S7-200PLC, the rest of the I/O modules and the AI module used for the water content detection adopt the UN200 series of EVERWEALTH, and the dosage metering is realised by PLY600, which is a dosage control instrument developed by Shandong POSHUO itself. In the UN200 module, the 8DI/8DO digital module is also used as the keyboard scanning module to collect signals for manual operation.

CP461-50 is very strict on the control system’s resistance to dust and other aspects. Previously, we used Siemens S7-300 PLC, the overall cost of the system is high, many users reflect that they want to reduce the price, but in the end, they still accept the high price, after contacting the module of EVERYWEAR, we decided to use the UN-300 series of modules instead of the corresponding AI, DI, DO modules after testing, using the CPU of Siemens 313C-2DP, and the power supply module of EVERYWEAR. power supply module.

CP461-50 is stable in performance and reliable in quality, meanwhile, our solution is also recognised by more and more customers, which fully meets the needs of the majority of building materials customers, and the actual application shows that: EVERWAY module greatly improves the production efficiency and economic benefits of the building materials production line.
