Description
TRUE: At least one locally assigned output of the
TwinSAFE group has an error
FALSE: All of the locally assigned outputs of the
TwinSAFE group have no errors
Description
TRUE: The function blocks assigned to the
TwinSAFE group are executed. When the
input is not linked it is in the TRUE state
FALSE: All of the TwinSAFE group assigned
function blocks are at a STOP state and
thus all associated outputs are in a safe
state.
All pending errors in the assigned function blocks and
in the TwinSAFE connections are acknowledged by
the FALSE->TRUE->FALSE signal sequence.
