WebbThe PLC test is a tool to access one's knowledge and skills in the maintenance and repair of programmable logic controllers (PLC). The test usually covers the core aspects of PLCs, such as programming, I/O devices, etc. Another substantial part of the test is dedicated to the interpretation of ladder diagrams and troubleshooting. WebbMTTF= T/N where T = total time and N = Number of units under test. Example: Suppose 10 devices are tested for 500 hours. During the test 2 failures occur. The estimate of the MTBF is: Whereas for MTTF MTTF= (10*500)/10 = 500 hours / failure. If the MTBF is known, one can calculate the failure rate as the inverse of the MTBF. The formula for
