• Operation of Differentiated Instructions in an MILR(518) Interlock
If there is a differentiated instruction (DIFU, DIFD, or instruction with a @
or % prefix) between MILR(518) and the corresponding MILC(519), that in-
struction will not be executed after the interlock is cleared even if the dif-
ferentiation condition of the instruction was established. (The system
compares the execution condition’s status in the cycle when the interlock
started to its status in the cycle when the interlock was cleared.)
In the same way, a differentiated instruction will not be executed if its exe-
cution condition is established at the same time that the interlock is started
or cleared.
• Example
When a DIFFERENTIATE UP (DIFU(013)) instruction is being used
and the input condition is OFF when the interlock starts and ON when
the interlock is cleared, DIFU(013) will not be executed when the in-
terlock is cleared.

1. When CIO 000000 is OFF (interlock starts), the DIFU's CIO 000001 input condition is OFF.
2. The DIFU's CIO 000001 input condition goes from OFF to ON while CIO 000000 is OFF (DIFU interlocked),
3. When CIO 000000 goes from OFF to ON (interlock cleared), DIFU is not executed even though CIO 000001 is still ON.
