REPLACEMENT OF THE MELSECNET/10 (REMOTE I/O NETWORK)

5.2.5 Parameter comparisons
(1) Parameters of remote master station
Basically, the parameter change is not required because A/AnS/QnA/QnAS series modules are
continuously used for the remote master station.
However, for a Q series MELSECNET/H remote I/O module (MELSECNET/10 mode), some parameters
must be set at the remote I/O station instead of at the master station, and therefore the setting change of
an existing module at the master station is required. For details, refer to Section 5.2.6.
(2) Parameters of remote I/O station
When mounting an intelligent function module on a remote I/O station, set parameters.
When the remote I/O station consists of only I/O modules, the modules operate without parameter
settings. (In such a case, the modules operate with the default values.)

A/AnS/QnA/QnAS series
MELSECNET/10 module
Q series
MELSECNET/H module
(MELSECNET/10 mode)
PLC
parameter
- PLC system setting
• New parameter of MELSECNET/H
(The number of empty slots is set.)
• For an A/AnS/QnA/QnAS series module, the number is set in
I/O assignments of the network parameter at the master
station.
- PLC RAS setting
• New parameter of MELSECNET/H
(The operation mode to be used or whether to enable the
error check at an error are set.)
• For an A/AnS/QnA/QnAS series module, the PLC RAS
setting of PLC parameter at the master station is relected to
the remote I/O network.
- Operation setting -
• New parameter of MELSECNET/H
(The parameters for data transmission between devices are
set.)
- I/O assignment setting
• New parameter of MELSECNET/H
(The I/O assignments of the remote I/O station are set.)
• For an A/AnS/QnA/QnAS series module, the I/O assignments
are set in I/O assignments of the network parameter at the
master station.
Therefore, at the replacement, if the I/O assignments are
already set at the A/AnS/QnA/QnAS series module on the
master station, the setting change is required.
• To mount an intelligent function module on a remote I/O
station, the switch setting is required for the I/O assignments.
Network
parameter
-
Ethernet -
• New parameter of MELSECNET/H
(The network parameter of an Ethernet module mounted on
the remote I/O station is set.)
CC-Link -
• New parameter of MELSECNET/H
(The network parameter of a CC-Link module mounted on the
remote I/O station is set.)
Remote
password
- Remote password setting -
• New parameter of MELSECNET/H
(The remote password of a module (such as an Ethernet
module or a serial communication module) mounted on the
remote I/O station is set.)
