CHAPTER 8 - CFW-09 OPTIONS AND ACCESSORIES
- Signaling LEDs indicating the status of the Profibus DP network
Whenpower is applied to the inverter and both on-lineandoff-line LEDs on the
Profibus DP board keep flashing, then a network address configuration or
installation problem may be present.
Check the installation and the network node address.
Use of the Profibus DP/related CFW-09 Parameters. Refer to item 8.12.7.
By using the DP-V1 communication kit, besides the exchange of cyclic data,
which is performedina similarform to that of ProfibusDP-V0,itis also possible
to perform services of reading/writing parameters through DP-V1 acyclic
functions, by the network master as well as by a commissioning tool. The
parameter mapping is done based in the slot andindex addressing, according
to the equationing below:
Slot: (parameter number - 1) / 255
Index: (parameter number -1) MOD 255
Indicates certain faults at the Fieldbus:
- Configuration error: the IN/OUT area size programmed at the board
initialization is different from the size programmed during the network configuration.
- User parameter data error: the size/contents of the user parameter
data programmedatthe boardinitialization aredifferent fromthesize/contents programmed
during the network configuration.
- Enabling error of the Profibus Communication ASIC.
rd is On-line at the Fieldbus.
- the board is off-line and the data exchange is not possible.
- the board is not On-line.
Indicates that the board is Off-line at the Fieldbus.
- the board is off-line and the data exchange is not possible.
- the board is not Off-line.
Valid only for the Profibus DP-V1 interface. It indicates that the board is processing a
- The board is executing a DP-V1 request.
- There is no DP-V1 request being processed.
- LEDs indicating the status of the Profibus DP network
MOD represents the remainder of the integer division.
Forinstance, theparameter P100 will be identified through theacyclicmessages
as being located at slot 0, index 99.
The value for the parameters is always communicated with a 2 byte (1 word)
size. The value is also transmitted as an integer, without decimal point, and its
representation depends on the used resolution.
E.g.: P003 = 3.6 A; value read via the network = 36.
