4.26

Signaling limit violation

Feature bit
Number of the Feature bit: 29
Signaling limit violation
With this Feature bit, you specify how limit violation should be sent to the respective limit
outputs. This concerns the outputs for the limits of the volume flow (VF_AH_Act,
VF_WH_Act, VF_WL_Act, VF_AL_Act) and the totalizers 1 or 2 (Tot1_AH_Act,
Tot1_WH_Act, Tot1_VF_WL_Act, Tot1_AL_Act or Tot2_AH_Act,
Tot2_WH_Act, Tot2_VF_WL_Act, Tot2_AL_Act)
The default setting is 0.
Bit = 0: Output value of the limit output = 1 (1 active)
Bit = 1: Output value of the limit output = 0 (0 active)
4.27 Resetting depending on the operating mode
Feature bit
Number of the Feature bit: 30
Resetting depending on the operating mode
When the "Protection" interlock, feedback error ("Runtime error", "Control error") or "Motor
protection" signal is present again, use this Feature bit to specify if a reset can be made
depending on the mode only by the operator in manual mode or only by the automatic I/Os in
automatic mode.
Resetting to manual mode is enabled with Feature Bit 31 (Activating reset of protection /
errors in manual mode (Page 63)). Also refer to the "Resetting the block in case of interlocks
or errors" section of the manual of the Standard APL blocks.
The default setting is 0.
Bit = 0: Resetting is independent of the operating mode
Bit = 1: In manual mode, manual resetting by the operator is only possible if Feature bit 31 is
set, otherwise resetting is not required in manual mode.
In automatic mode, only resetting via automatic connections is possible, regardless of
Feature bit 31. This is carried out by a 0-1 change in edge at the RstLi input or - with the
Feature bit 9 set - by a 0-1 change in edge at the automatic inputs e.g. DSrtAut.
