If VIK/NAMUR telegram is selected with P0922 = 20, the parameter P2038 "Selection of
actual profile" will be set to VIK/NAMUR automatically.
It is also necessary to set the ident number (GSD) via parameter P2042:
● SIMATIC Object Manager (Slave-OM)
For drives configured with SIMATIC Object Manager (Slave-OM) parameter P2042 has to
be set to 0 (default).
● VIK/NAMUR GSD (Device Data File)
For all other configurations the setting of parameter P2042 must be changed to 1
(NAMUR). That means that the VIK/NAMUR ID of the PROFIBUS Nutzerorganisation
(PNO) will be send to the PLC.
Note
If changing PROFIBUS standard telegrams to VIK/NAMUR telegram or back
(parameters: P0922, P2038 and P2042) the drive ID is changed. A power cycle is
necessary for the Control Unit CU240S to take the changed drive ID effective.
To change back from VIK/NAMUR to Standard telegrams it is necessary to set
P0922 = 999 (Free BICO connection) and then reset P2038 and P2042 to PROFIdrive
Profile. If P0922 = 999, it keeps the actual BICO connection parameters but now BICO
parameters can be changed.
