PLC Test – Form A4

A PLC instrument expert consulted with us to review this test. As a result, the former 50-item test became a new 60-item test, because we added 10 questions in a new category—Relays and Controls. In addition, we replaced five questions and updated seven others. Other categories include: PLC and I/O Basics; Ladder Logic; Programming Basics; Peripherals and Systems; and Troubleshooting.
