Which programming language is used in PLC?
Ladder logic
Ladder logic is the most common programming language used for programmable logic controllers (PLCs) in the U.S. Instruction list, function block diagram, structured text, and sequential function charts are all useful programming languages and may be more appropriate than ladder, depending on the application.

What is a sequencer in programming?
A sequencer is a highly convenient feature for programming machines or processes which operate in fixed sequences. These machines operate in fixed, clearly distinguishable step-by-step order, starting from an initial step and progressing to the final step and then restart from the initial step again.
What is a 16 step sequencer?
In most EDM, 16 steps is basically one measure (usually dance music is 120 BPM, with each beat subdivided into 4 16th notes. Sometimes, a song is 8th-note oriented, so if you set the sequencer to 8th’s, that’s two measures).
What is the 3 programming constructs?
The three basic programming constructs sequence is the order in which instructions occur and are processed. selection determines which path a program takes when it is running. iteration is the repeated execution of a section of code when a program is running.
Which is the second step in PLC programming?
Basic steps in PLC programming for beginners (photo credit: cyberspaceandtime.com) The second step in control program development is to determine a control strategy, the sequence of processing steps that must occur within a program to produce the desired output control. This is also known as the development of an algorithm.
How to start a PLC program at home?

Which is the second step in control program development?
The control task specifies what needs to be done and is defined by those who are involved in the operation of the machine or process. The second step in control program development is to determine a control strategy, the sequence of processing steps that must occur within a program to produce the desired output control.
