Bus status via PLC
(Bus status via PLC)
0 … 3
{ 0 }
This parameter decides whether the control word for the master function and the status word of
the frequency inverter are further processed by the PLC.
Setting:
0 = Off:
Control word for the master function (P503≠0) and the status word continue to be
processed by the PLC.
1 = Control word for master function via PLC: The control word for the master function
(P503≠ 0) is set by the PLC. For this, the control word must be redefined in the PLC by
means of process value "34_PLC_Busmaster_Control_word" (Section 4.2.2 ).
2 = Status word for Bus via PLC: The status word for the frequency inverter is set by the
PLC. For this, the control word must be redefined in the PLC by means of process
value "28_PLC_status_word" (Section 4.2.2 ).
3 = Control word and status word via PLC: See settings 1 and 2
