One trend in discrete part manufacturing is toward faster Node and higher precision part production – more parts per minute and better quality. Traditional control solutions can be stretched to their limits. By replacing traditional control solutions with time-based control, faster and higher precision goals can be realized. The IEEE 1588 standard provides a solution [...]

RSLogix Allen Bradley
Tags are the method for assigning and referencing memory locations in Allen Bradley Logix5000 controllers. No longer are there any physical addresses such as N7:0 or F8:7 which use symbols to describe them. These have been replaced with tags which are a pure text based addressing scheme. This is a departure from the more conventional [...]

Programmable Logic Controller
Before the advent of solid-state logic circuits, logical control systems were designed and built ex-clusively around electromechanical relays. Relays are far from obsolete in modern design, but havebeen replaced in many of their former roles as logic-level control devices, relegated most often to those applications demanding high current and/or high voltage switching. Systems and processes [...]

Programmable Logic Controllers (PLC)
Programmable Logic Controllers (PLC) is an electronic computer that is easy to use (user friendly), which has control functions for various types and various levels of difficulty. Definition Programmable Logic Controller (Capiel,1982) is: an electronic system that operates in digital and designed for use in industrial environments, where the system uses a programmable memory for [...]

The differences of PLC and DCS
In an article saying that the PLC and DCS has the same function. Currently DCS and PLC differences have become blurred as each has another take on the role. DCS PLC took some roles and vice versa. This is very different to that understood all along that: – DCS (Distributed Control System) as the name suggests is [...]

PLC basic elements
PLC is actually a special microcontroller system for the industry, meaning a set of hardware and software adapted for applications in the industrial world. Basic elements of a PLC is shown in the picture. Central processing unit or CPU is the brains of a PLC controller. The CPU is a microcontroller (microcontroller complete mini version). At the [...]
