LED display
Data Value
LEDs for signaling:
-> State of digital inputs 1 yellow LED per channel
-> State of digital outputs 1 yellow LED per channel
-> State of digital inputs/outputs 1 yellow LED per channel
-> Supply voltage available (Supply) 1 green LED
-> Battery 1 red LED (name: ERR) at the CPU
-> Program is running (RUN) 1 green LED
-> Controller-specific errors 1 red LED (name: ERR) at the CPU
-> CS31 bus Indication on CPU display under COM1 (CS31
bus is assigned to COM1 within the CPU)
-> Overload / short circuit of digital outputs Red LEDs on modules DA501/ DA502 and at
the CPU via ERR-LED. An indication on the
display is possible.
High-speed hardware counter
At the counting input, an external resistor of 470 Ω / 1 W must always be con-
nected upstream. For further information on high-speed counters, please refer
to the AC500 documentation.
