Affects IN_STOP
Output level
Meaning of OUT_READY 0 V = not ready
Meaning of
OUT_LINE_END
OUT_TEMP_PLC
OUT_FAULT_PLC
Output signal
channels 1–4
The signal levels / potentials of the binary input and output signals can be provided by the internal power supply of
the PICO controller or by a separate source (PLC, power supply unit, or similar device).
The switch stages of the binary input and output signals of the PICO controller are galvanically isolated from the
power supply at the factory. Depending on which source of potential is chosen, the following instructions must be
complied with when connecting to the 25-pin D-subconnector (Channels 1 to 4).
