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:

≡
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.
Bit 1 DisableVoltage

≡
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.
