[VIDEO] How to validate and check the hardware conditions of a PLC in the event of a failure

Hi, in this video I want to show you how we validate and check the hardware conditions in the event of a PLC failure

Although PLCs are robust, they often have faults, especially in their peripherals, that is, in the modules for entry and exit.

It often happens that failures in input and output modules generate errors in PLC control processes.

That's why we need to check these peripherals, as this leads to errors in the PLCs.

The PLCs themselves physically display some fault indicators; however, it is recommended to connect to the PLC program and check the fault logs.

We can review these errors through the PLC program, in the log of failures, where we will find a description of the error.

In the following image we can observe the error log of a PLC, and also what causes the error; in this case it shows an error due to an expansion module.

Once the error is recognized, it is necessary to review the module in error, correct it, and then delete the error from the program.

Now you have a clearer understanding of what we can do in the event of a PLC failure.
