1.2
Messages in output direction: PROFIBUS-DP master to the
SIPROTEC device
The messages in PROFIBUS-DP output direction (ref. to chap. 2.1, 3.1,
4.1 and 5.1) allow:
•
command outputs through the output relays of the SIPROTEC
device (external commands),
•
manipulation of taggings (internal commands), which can be
changed by PROFIBUS-DP.
Note
The allocation of the output relays to the switching devices and to the
output channels is defined during parametrization of the SIPROTEC
devices.
Depending on the device composition there may be less than indicated
output relays (and corresponding PROFIBUS-DP message positions)
available in the SIPROTEC device.
1.3
Messages in input direction: SIPROTEC device to the PROFIBUS-
DP master
The messages in PROFIBUS-DP input direction (ref. to chap. 2.2, 3.2,
4.2 and 5.2) allow:
•
polling of switching devices‘ status and binary inputs,
•
transmission of annunciations, measurands and meter values to the
PROFIBUS-DP master.
1.3.1 Annunciations
Note
The allocation of the input channels to the binary inputs is defined during
parameterization of the devices.
Depending on the device composition and the existing protection
packages not all of the indicated binary inputs or protection
annunciations (and corresponding PROFIBUS-DP message positions)
may be available in the SIPROTEC device.
