The DCS system causes belt trip issues
Thread Content
Our factory uses an ABB DCS system, and remote I/O is used to control the start and stop of the conveyor belt. The belt often stops automatically when the system is operating normally. No interference was found during on-site inspections, and by analyzing the trends, it was observed that each time the belt stops, the status indicators for \"ready\", \"operating\", and \"driving\" all disappear at the same time. Please help us, experts
It seems to be a problem with software communication; it is recommended to upgrade or take some other action. This is a case of system instability.
Preparation, operation, and drive all disappear at the same time? There must be a sequence involved – it’s possible that the signals for preparation or operation flicker, causing the DCS function blocks to fail to detect that preparation or operation has taken place, resulting in an immediate shutdown while the drive resets automatically
