3.2 Function List
3.2.1 Function list of the MELSECNET/10 remote I/O network
Basic
function
RAS function
Fuse blown error/I/O module
verify error check disable
function
Disables the detection of a fuse blown error or I/O module
verification error by the remote I/O station.
<Difference in comparison with the MELSECNET/10 remote
I/O station>
The disabled status can also be set in PLC parameter for
the MELSECNET/H (MELSECNET/10 mode) remote I/O
station using GX Developer.
Note that, however, if the error clear (disabled) status is set
on the remote master station, the module operates with the
setting of the remote master station regardless of the setting
on the MELSECNET/H (MELSECNET/10 mode) remote I/O
station. For details, refer to Page 49, Section 5.1.
Application
function
Transient
transmission
function
Routing function
Enables transient transmission to a station with another
network number in a multilevel system.
Link dedicated instruction
A dedicated instruction (ZNFR, ZNTO, JP/GP.ZNFR, and
JP/GP.ZNTO) to read/write data from/to the buffer memory
of special function modules mounted on the remote I/O
station from the remote master station
Default network specification
Enables communications with the network that is set in
parameter ("Valid module during other station access") by
specifying "254 (00FE
H
)" for the network number of the
access-target special function module.
Clock setting of stations in a
network
Sets clock data (date and time) to stations in a network
using a peripheral.
Clock data shall be set to the CPU module on the remote
master station.
(Only the QnA corresponding MELSECNET/10 network
module supports this function.)
The clock data set in the CPU module is transferred to
remote I/O stations.
Multiplex transmission function (optical loop
system)
Enables high-speed communications using a duplex
transmission path (forward loop and reverse loop) of the
optical loop system.
Number of return stations setting
Sets the number of communication error stations that can
go back to the data link within one link scan.
Reserved station function
Treats a station that will be connected in the future as a
reserved station, not as a communication error station. (The
station is included in the total number of connected stations,
but actually not connected.)
I/O assignment
Assigns I/O points to I/O modules and special function
modules mounted on the remote I/O station.
<Difference in comparison with the MELSECNET/10 remote
I/O station>
I/O points can also be set in PLC parameter for the
MELSECNET/H (MELSECNET/10 mode) remote I/O
station using GX Developer.
Note that, however, if I/O points are assigned to the remote
master station, the module operates with the assignment
set to the remote master station regardless of the setting on
the MELSECNET/H (MELSECNET/10 mode) remote I/O
station. For details, refer to Page 49, Section 5.1.
