SIPROTEC PROFIBUS-DP - Communication profile
C53000-L1840-B001-03
The information "Error sum alarm" (ref. to Figure 4-6) is transferred after routing to
"Destination system interface" (i.e. PROFIBUS-DP input message) at byte offset 5
th
(i.e. in the 6 byte), bit position 2
Note:
Only the positions in the PROFIBUS-DP message (byte offset, bit mask) are offered
to the selection on which the information type still can be routed according to the map-
ping file and the current occupancy.
Behavior at not routed positions in the PROFIBUS-DP message:
• In input direction the PROFIBUS-DP master always reads the value 0 from these
positions.
• A write command to not routed positions in the output message is ignored by the
SIPROTEC device.
Binary incoming annunciations (marked with the sign '>' in the name, e.g. ">BLOCK
81-1") cannot be routed directly as "Source system interface".
A control of these objects via PROFIBUS-DP as a substitute for using binary inputs is
however often meaningful.
To do this, taggings (information type: IntSP) routed to "Source system interface" as
well as "Destination CFC" are used.
The binary incoming annunciation which is routed as "Source CFC" is connected via
a CONNECT module in CFC to the tagging.
Control of object ">BLOCK 81-1" using a user-defined tagging "DP 81-1 bl" via PROFI-
BUS-DP:
• In the DIGSI Configuration matrix set the source for ">BLOCK 81-1" to CFC
output.
• Create a user-defined tagging using the Information catalog, rename this
object in "DP 81-1 bl", release it as "Destination CFC" and route it to an empty posi-
tion in the PROFIBUS-DP output message as "Source system interface".
• Open a CFC working page (e.g. "Device, Systemlogic" in run sequence PLC1).
• Insert a CONNECT module and check the run sequence of this module
(PLC1_BEA, MW_BEARB, ...) according to the selected CFC working page.
• Connect the input ("BO X") of the CONNECT module with the operand "DP 81-1 bl".
• Connect the output ("Y BO") of the CONNECT module with the operand ">BLOCK
81-1".
• Save and translate the CFC working page.
The object ">BLOCK 81-1" (and with that the associated protective function) can be
influenced by changing the value of the "DP 81-1 bl" via PROFIBUS-DP now.
