A Reference Signal is used to:
▪ Control an output based on the state of another output
▪ Represent the state of an output, input, safety function or logic block on another page.
When output SO2 is On, the SO2 reference signal state is On or High. The function block above
shows reference signal SO2 connected to the Reset Enable node RE of Latch Reset Block LR1.
LR1 can only be reset (turned On) when ES1 is in the Run state and SO2 is On.
