As the field of surgical robotics continues to evolve, it is important to keep patient safety in mind. This paper describes a safety control architecture aimed at moving an experimental system in the direction of intrinsically safe operation. The system includes safety features such as: a small number of states, Programmable Logic Controller (PLC) state transition control, active enable, brakes...

A stage suspended boom system is an automatic steeve system orchestrated by the PLC (programmable logic controller). Security and fault-recovering are two important properties. In this paper, we analyze and verify the boom system formally. We adopt the hybrid automaton to model the boom system. The forward reachability is used to verify the properties with the reachable states. We also present ...

The article is concerned with the issues of practical utilization controllers for automation in various technical fields as example Mitsubishi MELSEC FX1N and FX3U series. Any task, which requires electrical control devices, easy to solve by means usage programmable logic controllers. By using software programming package GX Developer, user has possibility program controller or input changes in...

There is a chance of leakage in the plumbing caused by water pressure pipes, improper installation pipe connections, or external influences, such as earthquakes. Plumbing that detected too late can cause damage to other systems. It necessary have detection system detect leak plumbing. Therefore, this research, designed with level detector (WLD) controlled programmable logic controller (PLC) typ...

A digitally programmable analogue Fuzzy Logic Controller (FLC) is presented. Input and output signals are processed in the analog domain whereas the parameters of the controller are stored in a built-in digital memory. Some new functional blocks have been designed whereas others were improved towards the optimisation of the power consumption, the speed and the modularity while keeping a reasona...
