Abstract

Embodiments of the present disclosure relate to a method for EPA link diagnosis, an EPA device and a storage medium, and relate to the communication field. According to this method, in response to the successful scheduling of the EPA system, periodic messages are sent via multiple ports in the current EPA device within the time slice corresponding to the current EPA device within the cycle time in the macrocycle; for each port: if determined The port is in a connected state, determining whether the periodic message from at least one other EPA device connected to the port in the EPA system has not been received via the port within a predetermined number of macrocycles; When the port receives the periodic message from at least one other EPA device, it is determined that at least one link between the at least one other EPA device and the port is faulty. Thus, the EPA periodic message can be used to detect the EPA link, without additional link detection message, reducing bandwidth occupation.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the communication field, and specifically relate to a method for EPA link diagnosis, an EPA device, and a computer storage medium. Background technique [0002] EPA (Ethernet for Plant Automation) bus, as China's first fieldbus standard with completely independent intellectual property rights, is also an international standard for industrial automation and has been widely used in the field of industrial automation and control. The EPA bus uses the physical layer of Ethernet as the transmission basis, and realizes high-speed, strong real-time reliable transmission through the EPA protocol. As the EPA bus has become more complex and network speeds have increased significantly, device and cable diagnostics have become increasingly time consuming and annoying. Contents of the invention [0003] Provided are a method for EPA link diagnosis, EPA equipment, and a computer storage medium, which can u...
