and LED for light-emitting diodes. On the left of each group is an accordingly labelled
button. By double-clicking these buttons you can show or hide the individual informa-
tion of the selected group.
In the column Status the current status of the particular hardware component is dis-
played. It is displayed symbolically. The actual states of the binary inputs and outputs
are displayed by the symbol of opened and closed switch contacts, those of the LEDs
by a symbol of a lit or extinguished LED.
The opposite state of each element is displayed in the column Scheduled. The display
is made in plain text.
The right-most column indicates the commands or messages that are configured
(masked) to the hardware components.

Password No. 6 (if activated during configuration) will be requested before the first
hardware modification is allowed. After entry of the correct password a condition
change will be executed. Further condition changes remain possible while the dialog

Test of the Binary
Each individual output relay can be energized allowing a check of the wiring between
Outputs
the output relay of the 7UM61 and the system, without having to generate the
message that is assigned to the relay. As soon as the first change of state for any of
the output relays is initiated, all output relays are separated from the internal device
functions, and can only be operated by the hardware test function. This means, that
e.g. a TRIP command coming from a control command from the operator panel to an
output relay cannot be executed.
