A Programmable Logic Controller ( PLC) can use a single START/STOP signal to com-
mand the START of a test cycle and to reset a running test.
The START signal should be a pulse, that can be lowered down when the "TEST RUN-
NING" signal is received.
The START signal must be lowered down before to start a new test.
If the START/STOP pulse is repeated while a test is running, the test is terminated
(reset).
If an input signal is programmed as RESET command, the reset input terminates the
running test and disables the start input (START).
All PLC inputs and outputs are PNP signal ( signal on at 24Vdc).
