How should the troubleshooting method for non-standard automation equipment be designed
Non-standard automation equipment is customized according to the individual needs of enterprises and falls under the category of non-standard products. So, how should we design solutions for malfunctions in non-standard automation equipment? Next, Shenzhen Jiukes non-standard automation manufacturer will introduce this to everyone.

Classification of the disadvantages of Fengbiao Automation
From the perspective of the causes of defects in non-standard automation equipment, defects can be divided into hard defects and soft defects. Hard defects mainly refer to components, internal leads of integrated circuits, circuits, jumper wires on printed circuit boards, etc., that cause defects. Soft defects mainly refer to changes in the internal logic status of surface equipment and the design of related system software and application software. Some defects are both hard and soft defects, such as communication defects.
The disadvantages of non-standard automation equipment can also be divided into static disadvantages and dynamic disadvantages. Static disadvantages refer to persistent and repeatable errors in the output of non-standard automation equipment given a fixed input. Dynamic disadvantages, on the other hand, are random or intermittent errors that only occur when there are changes in the signal. The former is relatively easier to investigate, detect, study, and eliminate compared to the latter.
The solutions to major malfunctions of automation equipment are as follows:
(1) Alarm. According to the actual needs of the automation equipment system, users can specify automatic alarms to be issued when certain events occur or when protective actions are taken. Generally, alarms can be set to be issued in the following situations: sudden change in switch value (such as protective tripping action); misalignment of circuit breaker position; analog value exceeding the set value; transformer protective action (such as gas and temperature). The over-limit value of the analog value can be modified online. Each alarm is displayed with time, alarm information, and confirmation status.
(2) Events. All action events in the automation equipment system, such as automatic protection actions, operations of circuit breakers, disconnectors, and grounding switches, can be automatically printed and stored in the system's hard disk memory. Each event is accompanied by time and relevant information in text form, and can be automatically printed and recorded.
(3) Protection functions and setting values that can be modified through the automation equipment system host or centralized control cabinet. All remote modification functions are online, and the modified setting values will be directly transmitted back to the corresponding storage device. Operation locking. The system can set locking functions for all operation objects to prevent misoperations by operators.
