Earthing and Grounding are very important criteria in designing a PLC system. It must be noted that impropergroundingcan result in physical hazards, electrical equipment damage, and worst case, even death. A PLC has grounding points in its power supply and input and output terminals. When you a...

Failure of a central module or a power supply.Initial situation: The S7-400H is in system state Redundant. 1. let the CPU0 fail by switching off the power supply.Result: At the CPU1 the LEDs REDF, IFM1F and IFM2F are on. The CPU1 goes into solo operation and the user prog...
In this system, two push-button switches are connected to discrete inputs on a PLC, and the PLC in turn energizes the coil of a motor contactor relay by means of one of its discrete outputs. Anoverload contactis wired directly in series with the contactor coil to provide motor over-curr...
Counting down is another operation that is widely used in PLC programming. In some cases you want to know how many counts are remaining before the limit is reached. With the up counter you can use some math to do it. But you can do it easily with a down counter. ...
PLC has a fast scan time (near about 10-15 ms for compact PLC). It requires very less operation time to perform any task. PLC gives a fast response to the connected system. PLC provides high accuracy as compared to the relay network. ...

This option can be used with --diff to perform line count diffs between git commits, or between a git commit and a file, directory, or archive. Use -v/--verbose to see the git system commands cloc issues. --git-diff-rel Same as --git --diff, or just --diff if the inputs are...
Analysis of Factors Which Reduce Operation Time in Performance of Single Incision Laparoscopic Cholecystectomy Conclusion: We found 3 factors related to a reduction in operation time: (i) avoidance of iatrogenic perforation of the GB, (ii) application of ... NL Yu,WY Kim,EH Choi - 《Journal ...
