Flags
*1 In CJ2, CS1-H, CJ1-H, CJ1M, and CS1D (for Single-CPU System) CPU Units, the Equals and Negative Flags are left unchanged.
In CS1D CPU Units for Duplex Systems, CS1 CPU Units, and CJ1 CPU Units, these are turned OFF.
Function
When the execution condition for IL(002) is OFF, the outputs for all instructions between IL(002) and
ILC(003) are interlocked. When the execution condition for IL(002) is ON, the instructions between
IL(002) and ILC(003) are executed normally.
The following table shows the treatment of various outputs in an interlocked section between IL(002)
and ILC(003).
Note Bits and words in all other instructions including TTIM(087), TTIMX(555), MTIM(543), MTIMX(554), SET,
RSET, CNT, CNTX(546), CNTR(012), CNTRX(548), SFT, and KEEP(011) retain their previous status.

INTERLOCK IL --- 002
Interlocks all outputs between IL(002) and
ILC(003) when the execution condition for IL(002)
is OFF.
