1 OVERVIEW
(6) Improved network functions
(a) Intelligent function modules mounted to remote I/O stations can be
diagnosed using the GX Developer system monitor.
Intelligent function modules mounted to remote I/O stations can be
diagnosed using the system monitor of GX Developer, which is connected
to a remote master station or directly connected to a remote I/O station.

When the network seems to be faulty, it can be diagnosed through GX
Developer connected to the remote master station or any remote I/O
station.
(b) If the GX Developer is connected to a remote I/O station, it will not affect the
system operating so user program network function testing can be done online.
It shuts out input (X) from the input module on the remote I/O station and
can turn input (X) on or off using the GX Developer test.
This allows testing of the remote master station input program to be performed.
In addition, it shuts of output (Y) form the remote master station and can
turn remote I/O station output (Y) on and off using the GX Developer test.
This allows testing of the wires for the output module on the remote I/O
station to be performed.
(7) Increased ease of network configuration in combination with GX
Developer
(a) The network parameters can easily be set by visualizing them as pull-down
menus, dialogue boxes, etc.
(b) The settings of network Nos., group numbers and operation modes have
been simplified so that these values can be designated only through
software settings.
