3500/60-01-05 Weighing and frequency converter communication adopts a new generation of automation bus standard Profinet communication based on industrial Ethernet technology, and the field adopts ring network communication mode. Touch screen communication adopts traditional Modbus TCP/IP communication. The whole communication has the characteristics of high speed, real-time, flexible topology and scalability, and meets the high requirements of industrial automation for communication.

For the communication of on-site weighing equipment, the PN slave station group ring network communication scheme is adopted, and the floor ring network switch is used to connect each floor weighing equipment to the PN master station, and the redundant characteristics of ring network are fully utilized to ensure efficient and stable communication. Due to the dense floor distribution characteristics of the pipeline and weighing equipment on site (each floor is equipped with an average of 50-60 devices, and a total of about 600 devices are distributed in three workshop3500/60-01-05 s), the project uses network cables to connect the weighing equipment on each floor end to end, and connects to the floor loop network switch to simplify wiring and improve system reliability.

For the communication of stirring equipment (frequency converter), the mode of star connection to the ring network switch is adopted, and the star connection to the ring network switch is connected to the PN master station through the PN slave station. Taking into account the characteristics of the centralized arrangement of the inverter, this scheme is more convenient for troubleshooting and has a small influence range.

Custom PDA scanning function on site

PDA scanning function according to the actual needs of the project customized design and application to optimize the field operation. In view of the complexity of the process of the field pipeline equipment, it is not enough to rely on the DCS central control room operation. After the introduction of PDA scanning code, it not only effectively alleviates the operating pressure of the central control room personnel, significantly improves the efficiency of the field operators, but also greatly enhances the ability of error prevention and error control. At the same time, the PDA scanning fu3500/60-01-05 nction collaborates with the Batch software and combines with the touch screen to realize the instant viewing of the formula information, ensures the efficient execution of the automatic dosing task, and promotes the full automation of the production process.
