Instructions for the use of MELSECNET(II), MELSECNET/10 and MELSECNET/H
(1) About relaying from the MELSECNET/10 loaded station
When the module is loaded to the AnNCPU or AnACPU, it is recognized as a
MELSECNET(II) module.
When the connected station is the AnNCPU or AnACPU, set the relayed network
as MELSECNET(II).
In addition, set the station number to "0" when making access to the control
station.
(2) Instructions for relaying the MELSECNET(II)
When access is made to the QnACPU, AnUCPU, QCPU (A mode) or motion
controller CPU via the MELSECNET(II), the device range is equivalent to that of
the AnACPU.
Instructions for use of computer link and serial communication modules
(1) About computer link communication
(a) If the connected station CPU is the AnUCPU and the computer link module is
the UC24 for computer link connection, remote operation will result in an error
when access is made to the AnNCPU, AnACPU or QnACPU via the
MELSECNET/10.
(b) On any computer link modules other than the UC24 and C24, remote
"PAUSE" operation will result in an error for all connections.
(c) For the QC24, note that the illegal case of specifying the first I/O number of a
non-existing module and reading/writing U
\G will not return an error if the
software version of the module is "k" or earlier.
(d) In any connection form (direct coupling, relaying) where the target station of
the UC24 or C24 is the QnACPU, an error is returned if clock data read/write
is executed.
(e) The FX extended port is required when performing the computer link
communication using FX
0N, FX1S, FX1N(C), FX3G, FX3U(C)CPU.
(2) Precautions for connecting personal computer and serial communication module
(a) When QJ71C24-R2 of function version A is used
An MX Component application can use only either of CH1 and CH2.
When the MELSOFT product, such as GX Developer or GOT, is using one
channel, the application cannot use the other channel.
When the QJ71C24-R2 of function version B is used, the application can use
both channels.
(b) When AJ71QC24-R2 or A1SJ71QC4-R2 or AJ71QC24N-R2 or
A1SJ71QC24N-R2 is used
The MX Component application can use only CH1.
It cannot use CH2.
