User Register
Via the [User Register] of the PROFIBUS-output-data the outputs DO1 (pin X6.1) and DO2 (pin
X6.2) may be operated. If the
{DO1}
-bit in the
[User Register]
is set to 1 the output DO1 on
connector X6 is pulled to ground, if set to 0 the output is high impedance. The
{DO2}
-bit
functions accordingly for output DO2.

In case of a PE35B-cabinet the outputs are used as follows:
DO1 is connected to the cabinet-operation-indicator (1 = indicator on, 0 = indicator off).
DO2 is connected to the cabinet-alarm-indicator (1 = indicator on, 0 = indicator off).
