RES-5006
Version 1
After the desired GSD file has been integrated into the design tool, one of the three communication modules
(“compact”, “expanded” or “complete”) must be selected. This determines the protocol over which the RES-5006
communicates with the PROFIBUS master.
To take advantage of the controller’s complete range of functions, the right GSD version must be
used. The GSD version to be used is noted on the controller’s rating plate.
The RES-5006 is completely downward compatible with its predecessor device RES-406 and can therefore also
be operated with earlier GSD versions. But not all functions are available then.

PROFIBUS protocol
The PROFIBUS protocol can be configured as follows:
• “compact” (16 bit for input and 16 bit for output data)
• “expanded” (2x16 bit for input and 2x16 bit for output data)
• “complete” (2x16 bit for input and 4x16 bit for output data)
The protocol is determined during project design by selection of the corresponding module (“compact”, “expanded”
or “complete”). The compact protocol enables efficient communication with the RES-5006. In the expanded pro-
tocol, the setpoint and actual value of the RES-5006 are separated from the status information and control func-
tions, so simpler decoding in the PROFIBUS master is possible. The complete protocol also provides the start tem-
perature at the time of activation of the ST bit and permits selection of one of the up to eight calibration data sets.
Bits 0…7 are low byte, bits 8…15 high byte (“INTEL format”).

from the PROFIBUS master to the RES-5006 contain the setpoint value and control func-
tions and are structured as follows:
