Production operation in case of failure of upper computer in concrete mixing station

Author: admin Release time: June 9, 2017 Number of visits:

When the upper computer of the concrete mixing station cannot be started, the PLC and buttons on the panel can be used to continue to control the production, but the production data and delivery order need to be manually recorded and filled in. At this time, continuous automatic and single plate automatic production mode can be carried out. If the PLC is powered on again, the number of disks for continuous production is four. If it is not powered on again, the number of disks continuously produced is the number of disks transmitted before the upper computer fails. The formula data should be manually set in the batching instrument. The target quantity of materials in the meter is the demand of a plate, not the demand of a square material.

About the function of disable and disable.

When a material in the formula is set to zero in the upper computer, the program will automatically set this material as disabled and pass it to PLC, which will skip this material and execute the program downward in the production process.

When the upper computer fails, if a certain material is not used, the target quantity of the material should be set to zero in the instrument, and the material should be disabled. The method of setting is as follows: first, press the "emergency stop" button; second, set disable or disable. When a certain material is disabled, press the stop button of the conveyor belt and the batching button of this material at the same time for more than 1 second. When it is disabled, press the start button of the conveyor belt and the batching button of this material at the same time for more than 1 second.

When the discharge door of the concrete mixer is opened, it will always be in the open state. At this time, the discharge door of the mixer can be manually opened and closed according to the needs, so as to fully clean the mixer door.
