QUESTION 5 The differences between a standard PLC and a safety PLC are: A standard PLC has one microprocessor, FLASH and RAM. A safety PLC has redundant microprocessors, FLASH and RAM. O Standard PLC inputs provide no internal means for testing the functionality of the input circuitry. O Standard PLC outputs provide no internal means for testing the functionality of the output circuitry. Safety PLCs have an internal output circuit associated with each input for the purpose of testing the input circuitry O Safety PLCs use power supplies designed specifically for use in safety control systems and redundant backplane circuitry between the controller and I/O modules All the above None of the above
