Modbus RTU vs Modbus TCP: Frames, Wiring, Speed and When to Use Each
Modbus RTU and Modbus TCP carry the same function codes and the same register model, defined in the Modbus Application Protocol specification. RTU sends compact binary frames over a serial line, usually RS-485, with one master, a slave address and a CRC-16. TCP wraps the same request in a 7-byte...
How to Build an OEE Baseline in Indian Plants Before You Buy an MES
To build an OEE baseline, pick one constraint machine or line, fix the definitions of planned time, ideal cycle time and a good part, then log downtime, output and rejects every shift, by hand if you have to. Calculate OEE as availability × performance × quality and keep the loss breakdown,...
How do you keep proving data center noise compliance after the site is built?
To keep proving compliance, an operating data center needs continuous boundary logging that compares day and night Leq with the CPCB zone limits (CPCB Noise Rules 2000) while chillers, dry coolers and DG tests change the plant from hour to hour. Log at fixed property line points facing the nearest...
OEE Monitoring System: What to Measure on Shop-Floor Machines
A setup that collects run state, part counts and reject counts from machines, and calculates availability, performance and quality, and their product, Overall Equipment Effectiveness (OEE)An OEE monitoring system needs three groups of signals from each machine: a reliable running or stopped state...
Digitise a Bursting Strength Tester: Peak Hold to Wi-Fi Log
A manual bursting strength tester can usually be digitised without replacing the machine. You add a pressure transducer on the hydraulic line, a controller with a display that shows live pressure and holds the peak at the moment of burst, a peak reset and tare, a field where the operator enters...
Retrofitting Legacy Machines and PLCs with OPC UA or Modbus
You can retrofit legacy machines without touching their control logic. Classify each machine first: PLC with Ethernet, PLC with serial only, relay or electromechanical, or no controller at all. Then read the PLC over Modbus or OPC UA using read functions only, or add sensors outside the control...
Data Center Noise Monitoring: Measure Against Indian Limits
Use a third-party sound level meter that meets IEC 61672-1 (Class 1 for compliance and disputes, Class 2 for screening), measure A-weighted Leq over day (6:00 a.m. to 10:00 p.m.) and night (10:00 p.m. to 6:00 a.m.) This is defined in India's Noise Pollution (Regulation and Control) Rules, 2000,...
Data Center Noise Levels Inside: Protect Staff Hearing
Data center noise levels inside the white space commonly sit in the mid 80s to mid 90s dBA, close to where long shifts start to damage hearing. In Maharashtra, Schedule XXIV of the Maharashtra Factories Rules, 1963 sets 90 dBA for 8 hours with a 5 dB exchange rate; NIOSH recommends 85 dBA for 8...
What is the CAN Bus? – The Ultimate Beginner’s Guide
The Language of Machines: A CAN Bus Journey The Silent Symphony Dawn broke over the city as Maya stepped out of her apartment building. The streets were quiet, save for the occasional hum of a passing car. She checked her watch; 6:30 AM. Perfect timing. Her friend Ethan would be arriving any...
Public, Private & Hybrid Cloud Types! Also Community Cloud!
Cloud computing has become an essential part of modern business, providing organizations with the ability to scale their computing resources on-demand and reduce costs. Among the various types of cloud computing, public, private, and hybrid clouds are the most commonly used by organizations....
How for organizations – it is cloud compliance that creates value and trust in security.
Cloud computing is a term that refers to the delivery of computing resources and services over the internet. It enables organizations to access and use computing resources, such as storage, processing power, and software, on-demand and without the need to invest in and maintain their own...
Why manufacturers don’t like cloud computing!
Some manufacturers may believe that their data is less secure if it is stored off-premises in the cloud, as opposed to being kept locally. However, studies have shown that the majority of security issues are a result of problems with in-house processes, rather than the cloud itself. There are...
