Set True / False
Digital input / output /
bit memory
STATUS_ERROR
Sets the output to 1 on a positive edge (0 → 1).
With the setting "True", the output remains permanently
at 1. Resetting via the "Reset" input is then only possible
when "RS/SR priority" = RS.
With the setting "Unused" or "False", the output is only
controlled by the inputs "Reset" and "Trigger".
Reset True / False
Digital input / output /
bit memory
STATUS_ERROR
On a positive edge (0 → 1) resets the output to 0 when
"Set" = 0 or when the "RS/SR priority" = RS.
With the setting "True" "Set" is permanently reset and the
output remains permanently set to 0.
With the setting "unused" or "False", the "Set" input is not
reset.
With the setting "Unused" or "False", the output is only

STATUS_ERROR
The edge change 0 → 1 of "Trigger" has the following
effect:
•
When "Set" and "Reset" = 0, the output is set to 1.
• When "Set" and "Reset" = 1 and the "RS/SR priority"
= SR, the output is set to 1.
•
When "Set" and "Reset" = 1 and the "RS/SR priority"
= RS, the output is set to 0.
• If only "Set" = 1, the output remains at 1.
•
If only "Reset" = 1, the output remains at 0.
The edge change 1 → 0 of "Trigger" has no effect:
