Process data assignment for fieldbus communication

The fieldbus communication is connected (preconfigured) to the previously selected
technology application by selecting the corresponding control mode in C00007:
 "30: CAN" for the connection to the system bus (CAN)
 "40: MCI" for the connection to a plugged-on communication module (e.g. PROFIBUS)
The assignment of the process data words does not depend on the applied bus system but
exclusively on the application:

• Only available for control mode "40: MCI".
Function
1 ≡ Change to the "SwitchedOn" device status
• This bit must be set in the CAN/MCI control word to ensure
that the device changes to the "SwitchedOn" device status
after mains connection without the need for a master control
specifying this bit via fieldbus.
• If control via a bus system is not wanted (e.g. in the case of
control via terminals), the wDriveCtrl output signal of the
LS_ParFix system block can be connected to the control word
inputs.
1 ≡ Inhibit inverter control (IMP - pulse inhibit)
1 ≡ Activate quick stop (QSP).
Activate/Deactivate quick stop ( 83)
1 ≡ Enable controller (RFR)
• If control via terminals is performed, this bit must be set both
in the CAN control word and in the MCI control word.
Otherwise, the controller is inhibited.
