Intfbk_In / Intfbk_Out (M1S Only, Max Number = 8); Terminator - Reer MOSAIC M1 Installation And Use Manual

INTFBK_IN / INTFBK_OUT (M1S only, max number = 8)

This operator can be used to create logical loops or to connect the output of a function
block to the input of another function block. IntFbk consist of IntFbk_In and IntFbk_Out;
after one M1S logical cycle delay, every IntFbk_In assumes the same logical value of the
corresponding IntFbk_Out.
INTFBK_IN
(scheme
side SX)
The element "IntFbk_Out" must have a number which, invoked by the corresponding
"IntFbk_In", allows the desired link.


If not carefully designed feedback loops could trigger dangerous system oscillations and as a
consequence makes the system instable. An instable system may have severe consequence to
the user like severe injuries or death.

TERMINATOR

This operator can be used as a terminator for
inputs not used in the scheme.
The input connected to the TERMINATOR operator
appears in the input map and its status is
transferred to the BUS.
