9.2.6 Node address
The Profibus DP node address has to be set in the field. This can be done in two ways:
• Two rotary switches on module can be set for 1...99.
• Setting the switches to 00 tells the module to use the address configured in the converter
menu. It can be set from 1...125. To set up address you go into the converter menu by
pressing ENTER and ↑ for 5 seconds together. Then go down to "Setup" and press ENTER.
Scroll down to "EXP. Module" and press ENTER. Screen will say "NODE ADDRESS 002".
Change address between 2...125 and then press ENTER to exit (The reason to start with no
002 is that the main control system normally is addressed as 001).
Do not forget to terminate box if this is the first or last item in loop as shown above.
9.2.7 GSD file
Each device on a Profibus DP network is associated with a GSD file, containing all necessary
information about the device. This file is used by the network configuration program during
configuration of the network. The latest version of GSD file can be received by contacting us.
9.2.8 Data structure
The data to and from the converter is structured as described in the table below. Total length for
input data is 84 bytes and for output data 4 bytes. We use "Big Endian".
INFORMATION!
The node address is not changed just by adjusting the settings. The converter must be turned off
for 10 seconds and then powered up for address to be recognized.
In/Out Type Length Name Content
In 57 16 byte Id Four bytes ID for each sensor. First byte (U8) is sensor
type (which is also the first part of the serial number),
second byte (U8) is middle part of serial number, the two
last bytes (U16) is the second part of the serial number.
In 51 4 byte Status One status byte per sensor slot.
Bit 0 Online, sensor is connected and measures.
Bit 1 Online, the sensor is flushing or brushing.
Bit 2 Frozen, the sensor value is frozen after
cleaning.
Bit 3 Alarm, the sensor has triggered a local
alarm in the converter.
Bit 4 Currently not used.
Bit 5 Currently not used.
Bit 6 Currently not used.
Bit 7 Currently not used.
In 40.5F 64 byte Value Four IEEE float values per sensor slot. First value is the
sensor output value, the rest is sensor dependant.
Out 61 4 byte Control One control byte per sensor slot. Currently not used.
