Intro to program control instructions
- [Instructor] Program control instructions are used to enable or disable a block of logic program or to move the execution of a program from one place to another. Basically, these instructions are used to control the flow of the ladder logic program. The use of program control instructions can shorten the time required to complete a program scan or alter the program scan from its normal sequence. In the PLC simulation software, you will find the program flow instructions under the program control tab.
