8 DTU3005P Profibus Application Notes

46 Siemens Energy & Automation, Inc.

1. Two additional words precede the real-time

data, increasing the amount of data transferred

by two words. The first word contains the

Device Number (0-31) as configured on the

DTU3005P’s device list and the second word

will contain the device type code as follows:

1 = SAMMS LV

2 = SAMMS LV

3 = 4300 Power Meter

4 = 4700 Power Meter

5 = 4720 Power Meter

6 = Statis Trip III

7 = ISGS Switchgear

8 = S7 I/O

9 = SB EC

2. If the input configuration size is greater than the

number of words in the real-time data list for a

particular device, the unused input words at the

end of the data transferred is set to 0.

3. If the input configuration size is smaller than the

number of words in the real-time data list for a

particular device, the words at the end of the list

are not sent (they are truncated).

For examples of the real-time input data transferred

to the Profibus-DP host for SAMMS devices see

Section 8.7.

8.5 Example: Real-Time Data for

SAMMS MV Devices

For an Input Configuration Size of 20, see Tab le 8 . 3 .

For an Input Configuration Size of 16, see Ta b l e 8. 4 .

Note: The Control Parameters and Ambient

Temperature will not be sent because all

20 input words are already used. An input

configuration size of 24 Words is required

to receive all currently used data for the

SAMMS devices.

8.6 Profibus Output Data

Output data transferred from the Profibus host to

the DTU3005P is used to tell the DTU3005P to

issue commands to the devices. Examples of these

commands are Reset KWH Counters, Turn a Relay

On or Off, or Change a parameter value like the Tim-

ing Byte for the SAMMS device. Use of the output

data from the Profibus host to the DTU3005P is

optional. When output words are configured, exactly

four words will be transferred from the Profibus-DP

host to the DTU3005P. For the format of these

words, see Ta ble 8.5 .
