Understanding Plc Cycle Time Optimize Your Automation One is using pulse stretch function shown in fig. 21.26. this function extends the length of the input signal until the plc looks at the input during the next scan, i.e. it stretches the duration of the pulse. Pulse stretch function. this function extends the length of the input signal until the plc looks at the inputs during the next scan. ( i.e. it stretches the duration of the pulse.).
Understanding Plc Cycle Time Optimize Your Automation A quick response module, sometimes known as a pulse stretcher, can be used to interpret extremely fast inputs. this module extends the signal such that it can last for at least one full scan. Pulse stretching is a function for stretching a short, digital input signal to the parameterized length. if the input pulse is already longer than the parameterized length, the pulse is not stretched. Understanding how quickly a programmable logic controller (plc) responds and how much work it can process is essential for optimizing industrial systems. response time and throughput are key metrics that help evaluate the efficiency of plc controlled processes. Pulse stretch function. this function extends the length of the input signal until the plc looks at the inputs during the next scan. i.e. it stretches the duration of the pulse.

Pulse stretch function. this function extends the length of the input signal until the plc looks at the inputs during the next scan. i.e. it stretches the duration of the pulse. It’s fine in this application, as plc #1 provides a near ideal pulse. however, real world signals such as switch bounce will trigger unnecessary hardware interrupts which could degrade the plc’s real time performance. What is the difference in response time when the output uses cyclic refresh and direct refresh? the time required from when the plc receives an input signal to when the plc outputs a control signal to the output terminal is the plc response time. By adding plc based process control units to the basic system configuration, plc process control functions can be simply added on to the basic functions already installed in the plc. This paper presents an application that can be used for determination of the response time of plcs that are used to perform the laboratory classes of the discipline that deals with the study of plcs.
