1.5.2 Control mode REMOTE
Control mode with control authority is REMOTE, option of unlocked
control with PROFIBUS-DP.
•
Changing the “Control mode REMOTE“ to UNLOCKED permits one
unlocked control operation via PROFIBUS-DP. After execution of
the command, the “Control mode REMOTE“ in the SIPROTEC
device will automatically be reset to LOCKED.
•
A programmed test “Switch in position“ for unlocked control
operations will always be executed.
•
If, after changing the “Control mode REMOTE“ to UNLOCKED, no
command is received via PROFIBUS-DP for a period of 5 minutes,
then the “Control mode REMOTE“ is automatically reset to
LOCKED.
•
If the “Control mode REMOTE“ was automatically reset to LOCKED
by the SIPROTEC device then this status can be recognized by the
corresponding bit in the PROFIBUS-DP input message. In this case
the status of “Control mode REMOTE“ in output direction has to be
updated by the PROFIBUS-DP master.

1.5.3 Changing the setting group
In order to change the setting group, the value “10“ = ON must be
transmitted for the corresponding pair of bits and afterwards be reset to
“00“ = “quiescent status“ (controlled by an impulse from the PROFIBUS-
DP master).
Switching ON one setting group automatically switches OFF the current
active setting group. Transmission of the value “01“ = OFF is
insignificant for the change of the setting group and is refused by the
device.
A change of the setting group is only possible via PROFIBUS-DP if the
parameter
C

A
NOTHER
S

G
ROUP
(parameter address =
302) has the value "Protocol".
