When SILa = SIL0, Should We Still Retain the SIL Rating in the Interlock Loop?

PLC /

In the field of process safety and instrumented system design, one common question often surfaces: “If a safety function has an achieved SIL (SILa) of SIL0, do we still need to retain that SIL rating in the interlock logic?” At first glance, the answer may seem obvious—SIL0 means “no required safety integrity,” so we can

Why RS-485 Struggles to Exceed 10 Mbps: A Deep Dive into Physical and Electrical Limitations

PLC /

RS-485 is a widely used serial communication standard known for its robustness, simplicity, and effectiveness over long distances. However, when it comes to speed, RS-485 has a clear upper limit—10 Mbps under ideal conditions—and most practical applications run well below that. But why is it so difficult to push RS-485 beyond 10 Mbps? Let’s break

Understanding Signal Processing in an Oscilloscope: DC Coupling vs. AC Coupling

PLC /

Oscilloscopes are essential tools in electronics for visualizing electrical signals. One key feature that users often need to understand is the difference between DC coupling and AC coupling. These modes control how the oscilloscope processes the input signal, either displaying all components of the signal or focusing specifically on its alternating current (AC) parts. In

Designing Gas and Liquid Piping Systems: Why A Beautiful Drawing Doesn’t Guarantee a Good Design

Pipeline /

In large-scale chemical, power, and petrochemical projects, piping and instrumentation may seem inconspicuous, but they are the “nerves” and “blood vessels” of the entire facility. When designed properly, systems operate reliably, require less maintenance, and deliver accurate data. When designed poorly, they become sources of error, constant alarms, frequent repairs, or even serious safety hazards.
