Datasheet

ChanDi object. Representation is set to Bit8, Bit16, Bit32 or Bit64 dependent on the size of the

word, and in Number the bit number that contains the channel value is stated (first bit has number 0

Analog inputs

An analog input is usually transferred as a integer value and specified with a ChanAi object.

Representation matches the integer format in the transfer. In some cases the value is sent as a float,

and the float format has to be stated in FloatRepresentation (FloatIntel or FloatIEEE) in the slave

object. Ranges for conversion to engineering value are specified in RawValRange,

ChannelSigValRange, SensorSigValRange and ActValRange (as the signalvalue is not used

ChannelSigValRange and SensorSigValRange can have the same value as RawValRange).

Digital outputs

Digital outputs are specified with ChanDo objects. Representation should be set to Bit8, Bit16,

Bit32 or Bit64 dependent on the transfer format.

Analog outputs

Analog outputs are specified with ChanAo objects. Set Representation and specify ranges for

conversion from engineering unit to transfer value (set ChannelSigValRange and

SensorSigValRange equal to RawValRange).

Complex dataareas

Many modules sends a mixture of integer, float, bitmasks etc. You then have to combine channel

objects of different type. The channelobjects should be placed in the same order as the data they

represent is organized in the data area. For modules with both in and out area, the channels of the

inarea i are usually placed first and thereafter the channels of the outarea.

Driver

Softing PROFIboard requires a driver to be installed. Download the driver from www.softing.com.

Agent object

Pb_Profiboard

Agent object for a profibus master of type Softing PROFIboard. The object is placed in the

nodehierarchy below the $Node object.

Slave objects

Pb_Dp_Slave

Baseobject for a profibus slave. Reside below a profibus agent object. In the attribute GSDfile the

gsd-file for the current slave is stated. When the gsd-file is supplied the slave can be configured by

the Profibus configurator.
