Discrete Output block
The Discrete Output block is fully configurable and provides characterization for the outgoing signal.
Depending on the value of
OUT_D
the corresponding "True/1" or "False/0" signal is forced at the
electrical output of the connected module relay output module SFC428, SFC432, SFC435 or
SFC438.
Fig. 5-8 Schematic diagram of the Discrete Output block
Procedure
1 In the fieldbus view, right click on the Discrete Output block
Device Tag-DO-n
and select
Off
Line Characterization
. The Characterization dialog opens.
– Press the
ALL
button in the toolbar to display all parameters
2 Expand the
MODE_BLK
node and set the Target Mode to Auto
–
Select the
Target
node then click the
Edit
button
–
Select
Auto
from the drop-down menu, click
End Edit
to confirm the selection
–
Click
Close
to leave the dialog.
3 Set
CHANNEL
to the input connected to the block as defiined in Section 5.3.1
–
Select
CHANNEL
, then click the
Edit
button
–
Enter the CHANNEL value (Rack+Slot+Group+Slot)
–
Click on
End Edit
4 If you want to invert the signal do it as follows:
–
Select the
IO_OPTS
parameter and click on
Edit
–
Select the
Invert
option and click
End Edit
5 For a delayed output on recognition of a fault, use the
FSTATE_TIME
parameter
–
Select the
FSTATE_TIME
parameter and click on
Edit
–
Enter the delay time (s) then click on
End Edit
.
6 Repeat the process for all inputs to DO blocks
Properties
The DO block forces the output signals as shown in Table 5-7. NO (Normally open) and NC
(normally closed) is the state of the relay when power is not applied.
