3. SYSTEM CONFIGURATION
(d) When a QnACPU is mounted on a main base unit for A38HB/A38HBEU high-
speed access, the QnACPU can access special function modules, intelligent
special function modules and link modules to write/read at greater speeds.
QnACPU cannot input/output to the I/O module at greater speed.
(e) The following shows how to connect graphic operation terminal units to a
QnACPU.
(f) The accessible range for an AJ71UC24 computer link module comprises the
CPU to which the AJ71UC24CPU is mounted (the host station) and the other
stations in the network to which the host station is connected.
It is not possible to access other stations in other networks by using the
MELSECNET/10 network system routing function.
The access range for an AJ71QC24N serial communication module is the host
station, other stations in the network connected to the host station, and other
stations in other networks accessed through up to 7 relay stations by using the
routing function.
(g) When accessing from intelligent communication module AD51H-S3 to other
station QnACPU on the network, only Format 1 control table can be used.
Format 2 control table cannot be used.
Access to other network is not allowed on Format 1 control table.
(h) In QnACPU, I/O assignment set with the parameter cannot be valid for
MELSECNET (II) and MELSECNET/B. When setting the I/O assignment for a
remote I/O station, build the remote I/O network with MELSECNET/10.
