Jitter Rejection: FATEK M PLC (Hard PLC) Scan Cycle Stability
Reject jitter: FATEK M PLC
Scan cycle stability
In precision machining and continuous production lines, the "scan cycle stability" of the controller is the core that determines product consistency. Once jitter occurs, the action timing will be misaligned. FATEK M PLC With exclusivePure hard core architecture, achieving nearly 0% execution jitter, ensuring system performance remains the same.
FATEK M PLC (Hard PLC) is a programmable logic controller that adopts a pure hardware drive architecture. The control logic is solidified in the hardware circuit for execution and does not rely on operating system scheduling. Therefore, the scan cycle jitter (Jitter) approaches 0%.Its core positioning is to solve the cycle instability problem of traditional Soft PLC (based on PC or system architecture) due to operating system scheduling and resource competition, ensuring that processes such as precision dispensing and high-speed flying shearing that require extremely high timing consistency can still maintain exactly the same scan cycle as the first second after power-on during long-term operation.
Scan cycle stability
The scan cycle jitter of M PLC approaches 0%, while the jitter of traditional Soft PLC fluctuates as high as 30%. There is an order of magnitude gap between the two in timing accuracy.In order to verify the stability of M PLC under long-term high-load operation, we conducted comparative observations between Hard PLC (M PLC) and traditional Soft PLC (based on PC or system architecture) through precision physical instruments.
The signal intervals displayed by the oscilloscope are extremely regular, and the jitter fluctuation is close to 0%.
The signal interval shows irregular deviations visible to the naked eye, and the jitter fluctuates up to 30%.
Why does M PLC run with almost no system lag?
M PLC runs with almost no system lag because it is driven by pure hardware and does not go through the operating system scheduling layer.Since M PLC is a pure hardware driver, itCommon crashes, lags and system errors in the innate immune operating system. Even if it runs continuously for several years, its scan cycle is still exactly the same as the first second after power-on. This "consistent" quality is the cornerstone for the success of processes that have extremely high timing requirements, such as precision dispensing and high-speed flying shearing.The prerequisite is that the control logic must be solidified during deployment; the limitation is that this stability is guaranteed at the hardware level, and it still needs to be matched with correct peripheral circuits and heat dissipation design.
Summary of advantages: long-term and stable business value
The commercial value of M PLC lies in its nearly 0% jitter and performance that does not decay over time, in exchange for the three major advantages of extreme consistency, long-term stability, and easy system maintenance, which directly improves the overall equipment efficiency (OEE).The evaluation criteria are jitter fluctuation rate and long-term performance attenuation; the limitation is that the logic change flexibility of the hardware architecture is low, and the stability of the process logic needs to be confirmed before introduction.
Ultimate consistency
Almost 0% jitter means that every action and every cycle is triggered at a precise time, ensuring consistent production quality.
long term stability
Performance does not degrade over time, eliminating the need to regularly restart the system to free up resources, significantly improving overall equipment effectiveness (OEE).
System is easy to maintain
There are no virus threats and no compatibility risks caused by system patch updates, allowing the control system to return to its purest and most reliable state.
Frequently asked questions: Scan cycle stability and selection diagnosis
Q1: What actual impact does scan cycle jitter (Jitter) have on the production line?
Scan cycle jitter will directly lead to misalignment of action timing, resulting in reduced product consistency and loss of process yield.When the jitter fluctuation reaches 30%, the triggering time points of each cycle are inconsistent. In timing-sensitive processes such as precision dispensing and high-speed flying shear, problems such as uneven glue volume and cutting length deviation may occur. The jitter of M PLC is close to 0%, so that every action is triggered at a precise time point, ensuring that everything is consistent.
Q2: Will the "0% jitter" of M PLC decay after long-term operation?
No, the scan cycle of M PLC does not decay with the running time, and it will still be exactly the same as the first second after power-on for several years of continuous operation.This is because M PLC is driven by pure hardware and does not go through the operating system scheduling layer, so it is inherently immune to system crashes, freezes, memory fragmentation and resource competition and other software layer attenuation factors. In contrast, Soft PLC needs to restart the system regularly to release resources, otherwise jitter and delay will accumulate over time.
Q3: Under what circumstances should M PLC be chosen instead of Soft PLC?
When the production line has extremely high requirements for timing consistency and the control logic is stable and does not require frequent changes, M PLC should be selected.Typical scenarios include precision dispensing, high-speed flying shears, continuous production lines, etc. These processes are extremely sensitive to scan cycle jitter, and require long-term performance without degradation. If the production line needs to be deeply integrated with the IT system, or the control logic needs to be modified frequently online, the software flexibility of Soft PLC may be more suitable. The boundary restrictions that need to be evaluated before importing are: M PLC logic changes need to be done through hardware programming or special tools.
Q4: How to diagnose the problem of high scan cycle jitter?
First, use an oscilloscope to collect the PLC output signal waveform and measure the fluctuation rate of the waveform interval to quantify the degree of jitter.If the jitter is high, common reasons under the Soft PLC architecture include heavy operating system scheduling load, background program competition for resources, insufficient memory, or driver abnormalities. Under the M PLC architecture, since the operating system layer is not passed, the above software factors can be eliminated and the focus can be directly on power quality, peripheral circuit interference, and hardware heat dissipation status.
