fy3000s one-key sequential control intelligent error-proof system is a perfect and reliable error-proof solution exclusively for the one-key sequential control mode. the system consists of an intelligent error-proof host and sequential control error-proof management software. it interfaces with the sequential control monitoring host and the original error-proof system to obtain the status of the whole equipment, and realize the logical verification of the one-key sequential control operation ticket and the instruction execution process of the intelligent monitoring host, so as to ensure the correct execution of the one-key sequential control of the monitoring host and avoid misoperation.
