Software or hardware cause analysis of PLC crashes - Database & Sql Blog Articles

KKST SMD Plug-in Active Passive Crystal Magnet Hot Sale 4.915200MHZ

When plc is running, there may be a crash, which causes unpredictable loss to industrial production. Therefore, first understand the cause of the PLC crash, and troubleshoot the cause. Software or hardware errors may cause the PLC to crash. Introduction:
1. Hardware (1) I/O power, PLC automatically detects I/O error and enters STOP mode.
(2) If the I/O is damaged, the program runs to the feedback signal that requires the I/O, and the instruction cannot be executed downward.
(3) Expansion module (function type, such as A/D) line interference or open circuit.
(4) There is interference or malfunction in the power supply section.
(5) The connection module of the PLC and the address assignment module have failed.
(6) The fault caused by the cable.
2. The software aspect (1) triggers an infinite loop.
(2) The program rewrites the contents of the system parameter area, but there is no initialization part.
(3) Protection program startup: hardware protection, limited use time (recovery for payment)
(4) Data overflow, too large step size, watchdog (can modify DOG time) action.

Through-bore Slip Ring

A through-bore slip ring is an electrical device that allows current to pass between two points in a rotating assembly without a physical connection. There is no break in the circuit. This is accomplished by passing the current through a rotating brush that contacts a stationary metal ring. The metal ring is mounted on the shaft of the assembly and provides a continuous path for the current.

Through-bore Slip Ring

It is an integrated circuit component that consists of two conducting rings that are separated by a gap or spacer. When the rings are brought into contact, current can flow between them and produce a rotational motion. Slip rings are used in various applications where high efficiency and low power consumption are essential, such as communication systems, motor control systems, and energy harvesting devices.


The through-bore design allows for rotation of the assembly while transmitting power or data. They are often used in applications where there is a need to rotate an object while keeping a power or data connection open, such as on a wind turbine or radar antenna.


The Oubaibo's through-bore slip ring is a newly designed product that has many advantages over other products on the market. It is small and lightweight, making it easy to install and use. The through-bore design also allows for a high degree of flexibility, making it ideal for use in difficult or tight spaces. Additionally, the Oubaibo through-bore slip ring is very efficient, providing a high degree of power transfer with minimal loss.
