PLC Work

After PLC is powered on, the system self-check and the initialization of memory should also be carried out to prepare for the normal operation of PLC.

Scanning works by running the program over and over again to achieve control.

PLC is the basic way of working.

In addition, in order to cope with urgent tasks, THE PLC also interrupted the working mode.

In interrupt mode, the task to be processed requests an interrupt first, and the running program is stopped after being responded to, and then the interrupt work is processed (running the service program related to the interrupt).After the interrupt is processed, it returns to run the original program.

The INTERRUPT mode of a PLC task, or event, is hierarchical.When two or more interrupt events occur at the same time, the higher priority is processed first, followed by the lower.

Until all interrupt tasks have been processed, proceed to scan.

PLC for a large number of controls are used to scan the way to work, and for individual urgent processing, with interruption.

In this way, all controls can be taken care of while individual emergency tasks can be handled in a timely manner.

Of course, the actual working process of PLC is more complex than here, analysis of its basic principles, there are also some theoretical problems.

But if you can make clear the idea introduced above, also know how to work PLC.
