Terminal bus fault (operating
voltages VVEN, VAUS or VSEN
below the tolerance, short

Check the operating
voltages at Pin 1 and Pin 2.
•
Eliminate short
circuit/overload.
* When the operating voltage for the terminal is switched on, the LEDs NET,
GRR and I/O flah simultaneously (switch-on and initialization phase). If they
do not cease to flash, the set field bus address is already occupied by
another slave. Error handling: Switch off the operating voltage and set another
(unreserved) field bus address in the node of the terminal.
