Communication Interfaces: It supports a variety of communication interfaces such as Ethernet and serial communication.
PROFIBUS – DP: It is used for data transmission on the master station control bus. The baud rate ranges from 9.6k to 12M, and the number of bus devices is 126. The main mode between the master station and the slave station is cyclic operation, which complies with the EN50170 standard. The master station can read and write its own slave stations, and can only read the slave stations of other master stations. There is no direct data exchange between master stations. Non-cyclic (DP – V1) operations such as parameter setting and diagnosis can also be carried out between the master station and the slave station, which can be synchronized with the cyclic data transmission between the master station and the slave station.
Modbus RTU: It is an open master/slave protocol and can communicate through the COM1 and COM2 ports (RS232 or RS485) integrated on the AC500. The COM1 and COM2 ports can both work as Modbus interfaces simultaneously, and the Modbus working mode of the interfaces can be set through the engineering tool. The topological structure supports RS232 point-to-point (with a cable length of 15 meters) and RS485 multi-point (one master station and up to 31 slave stations, with a cable length of 1.2 kilometers).

ABB PPC902AE101 | 3BHE010751R0101 | Excitation control module.The ABB PPC902AE101 3BHE010751R0101 is an excitation control module. It is used in industrial control automation systems, specifically in the field of thermal power plants. This module plays a crucial role in maintaining the stable and reliable operation of thermal power units.Implement whole process management for DCS (Distributed Control System) equipment and maintenance. This includes early detection of defects and timely resolution. Enhance the self-diagnosis and fault alarm functions of the DCS system. Real-time monitoring of the DCS operation status should cover not only the main controller but also the status of the main controller network.excitation control module is located. Access the DCS display to track real-time changes in temperature.【ABB PPC907 】If necessary, install an independent air conditioner or dehumidification device to maintain the appropriate temperature and humidity levels in the electronic room.
