RS_STATE
The current state of the device. TableC-13 lists device states.
SAFEGUARD_CL
An interlock input. When in Discret_State_1, the output of the block is
forced closed (Discret_State_0). This interlock input has priority over
all other interlock inputs.
SAFEGUARD_OP
An interlock input. When in Discret_State_1, the output of the block is
forced open (Discret_State_1). This interlock input has priority over all
other interlock inputs except SAFEGUARD_CL.
SET_FSTATE
Allows the user to set the device faultstate to active. This, in turn, forces all
output blocks into their own faultstate behavior.
SHED_OPT
Controls the way blocks enter mode shedding. Each option listed below has
a companion No Return option. The No Return shedding options change
the target mode of the device to the shed mode and prevent the device from
re-entering RCas or ROut mode after the shed condition has ended.
TableC-14 lists shed conditions. Refer to Appendix D, Advanced Function
Block Behavior, for more information about mode shedding.
