Ladder log is the programmable language used to frame codes for PLC. Using Ladder Log the circuits can be created and represented in ladder form. The programmable logic controls can be commenced wielding the Ladder Log.
Ladder log yields programs for PLC as it is the basis of hard real time systems. Its applications can widely be seen in electromechanical industries. It is the backbone for assembly devices and robotic lines in manufacturing industry. This in wider sense contributed in eliminating the use of those hard wire bounded system and marks the way to a relatively new era of flexible devices capable of tolerating all weather conditions.
Ladder log is implemented in traffic lights where strict time constraints needs to be followed as just a midget can lead to a great defilement.
