Description
This mode can be selected for optimizing the performance of cyclic
transmission based on the frequencies of cyclic transmission and
transient transmission.
The mode can be selected from "Online (Normal Mode)" and
"Online (High Speed Mode)".
The link devices (RX, RY, RWr, RWw, SB, SW) of the master/local
module (QJ71GF11-T2) are read or written directly.
Reserved station specification can be temporarily canceled without
changing the parameters.
A relay station transfers the link devices of the master station and
submaster station to another network module.
By setting the routing parameters (communication path) using GX
Works2 in advance, transient transmission can be performed to
stations on different networks through dedicated instructions or GX
Works2.
Communication can be also performed between CC-Link IE Field
Network and Ethernet, CC-Link IE Controller Network,
MELSECNET/H, and MELSECNET/10.
The network configuration can be checked by the CC-Link IE Field
Network diagnostics of GX Works2.
The network line status and parameter setting status of each station
are checked.
Connection status of the Ethernet cables is checked.
Whether the communication route for transient transmission from
the own station to the destination station is correct or not is
checked.
When the IP packet transfer function is used, whether no error
occurs in the communication route is checked.
The history of events that occurred in the own station and on the
network is displayed. For the master station, the event history of the
entire network can be displayed, and so it can be used for
troubleshooting at network start-up.
Slave stations that are not set in the master station parameters can
be added during data link.
Communications in a protocol, such as FTP and HTTP, by
specifying the IP address of an Ethernet device can be performed
over CC-Link IE Field Network.
With this function, two networks of CC-Link IE Field Network and
Ethernet are not required, resulting in reduced wiring cost.
The station number of a local station can be set using the dedicated
instruction (UINI instruction). When processing contents are the
same in multiple local stations, managing the project of GX Works2
by each station number is not required.
