Watch PLCs from past and present

Welcome back to Om-ron PLC dot com ,Today i have article that story in PLCs,Twenty-five years I was in my last year with Allen-Bradley PLC and a specialist and educator. I grew up with the PLC in 1774, the PMC. What a trip through the PLC-2, PLC 3, PLC 5, computer-based programming instead of a luggable terminal and a 10 MB hard disk for the PLC-3 GA module for remote data collection and programming remotely through the RM modules.

plc STORY

A laptop for programming (Data General) was more than $ 8,000. Hard drive space is outrageous expensive, and Windows will not be used. PCs were ahead, and programmers learned useful DOS software.
From 1977 to 1985 there was an enormous growth pattern that most had not imagined. Remote I / O, HMI, SCADA, and similarly, the PLC to the DCS world compromise. Servo Control was also available. Special keyboards set them up.

Bit-flipping was an art.

We had to do in ASCII module interfaces, and network modules with interfaces for mini-computers like the DEC VAX and PDP-11. (more…)

PLC programming for 3 phase motor starting

PLC programming today will be present operation of the circuit in the 3 phase motor with more horsepower will have to control Star - Delta, to prevent current surges.
1. When the ON switch input 00002 (S2) output will be 00200 and 00201 output status ON.
2. Motor is a delta function.
3. Now outputs 00200 and 00202 to work with the output ON state simultaneously.
4. To stop the switch to ON input 00001 (S1).
5. When the input overload condition 00003 will work to stop motor rotation.
