CQM1 Master Units
Recognition of Slave I/O
Status at Startup
When the CompoBus/S System is turned ON, the I/O of Slaves connected to
CQM1 Masters may not become effective at the same time as the I/O of
Slaves connected to CS-series, CJ-series, C200HX/C200HG/C200HE-(Z)E,
and C200HS Masters.
CS-series, CJ-series, C200HX/C200HG/C200HE-(Z)E, and C200HS
Masters
The I/O of a Slave connected to a CS-series, C200HX/C200HG/C200HE-
(Z)E, C200HS, or CJ-series Master becomes effective when the Active Node
Flag for the Slave goes ON.
CQM1 Masters
The I/O of a Slave connected to a CQM1 Master becomes effective some time
after the Master’s PLC is turned ON.
In High-speed Communications Mode: (PLC cycle time) + 118 ms
In Long-distance Communications Mode: (PLC cycle time) + 720 ms.
