Practical Tips and Techniques
This offers ways in which you can learn PLC programming.
The Click PLC has automatic linear scaling for the analog inputs and outputs. What if the analog input or output is not linear? How do you handle this in the PLC? Look at the following tank. We can measure the height, which is linear, but the volume will not because of the shape of the … Read more
Most programmable logic controller (PLC) programs will include a counter instruction. The Productivity 2000 Series PLC has two different counter instructions for your program. These can be used in several different ways to adapt to your application. Basically, counters are used to count up or down to a specific limit. When the limit is reached, … Read more
The EasyPLC palletizing robot will demonstrate sequencing and robot control using a PLC. This palletization process will fill a box container with six cans. A servo-controlled gantry robot using x and y is used to do this operation. The complete box will then travel along to another conveyor to an unloading area. A robot will … Read more
Logic circuits in a PLC ladder logic program are either on or off. The inputs change, which will affect the outputs. This can be expressed in a timing diagram. The timing diagram or chart will show you how the ladder logic program will respond to the changing states of the inputs and outputs. This visual … Read more
Timers are one of the first things you learn about programmable logic controllers. (PLC) Just about every PLC program will include timer instructions. The Productivity 2000 Series PLC has several different timer instructions for your program. We discussed the timed coil (TMC) and flasher coil (FLS) last time as part of the ladder logic output … Read more
The EasyPLC machining center loading robots will demonstrate sequencing and robot control using a PLC. Two input lines feed blanks to the robot. The robot will alternate taking the blanks and putting them into the CNC (Computer Numerical Control) machine. The robot moves the piece to the finished conveyor when the part has been machined. … Read more
