2.8.6 DCTRL_wFaultNumber
An existing fault can be read using the system variable
DCTRL_wFaultNumber
= C0168.
For the assignment of the error numbers refer to chapter ”Monitoring” of the description of the
automation system.
2.8.7 DCTRL_bExternalFault_b
If
DCTRL_bTripSet_b
triggersaTRIP,thenthestatechangesfrom
DCTRL_bExternalFault_b
toTRUE.
DCTRL_bExternalFault_b
remains TRUE, until either
DCTRL_bTripSet_b
, keypad, GDC or codes
reset the TRIP.
2.8.8 Controller state
The state is binary-coded in the system variables
DCTRL_bStat1_b
...
DCTRL_bStat8_b
(VAR_INPUT).
DCTRL_bStat8_b DCTRL_bStat4_b DCTRL_bStat2_b DCTRL_bStat1_b Action of the controller

2.8.9 Output of digital status signals
Defined signals areoutput at
DCTRL_wStat
as a status word. With C0150 you can display the status
word.
The status word is assembled from the following signals:
• Generated signals in the SB DCTRL
• Signals from system variables, with outputs that you can program
System variables, which you can use to assign defined signals
to the status word
Signals generated in SB DCTRL, that are assigned to the status
word
DCTRL_bStatB0_b DCTRL_bImp_b
DCTRL_bStatB2_b DCTRL_bNActEq0_b
DCTRL_bStatB3_b DCTRL_bCInh_b
DCTRL_bStatB4_b DCTRL_bStat1_b
DCTRL_bStatB5_b DCTRL_bStat2_b
DCTRL_bStatB14_b DCTRL_bStat4_b
DCTRL_bStatB15_b DCTRL_bStat8_b
DCTRL_bWarn_b
DCTRL_bMess_b
The bitwise assignment of the status word can be found in the diagram for the SB DCTRL (see
Abb. 2-15).
