1 OVERVIEW
(7) Connecting the GX Developer and the GOT
(a) Connecting the GX Developer (Details are explained in the GX Developer
Operating Manual.)
• By connecting a PC installed with a GX Developer to the interface of the Q
series C24 at the same time, operations such as programming, monitoring
and testing for the PLC CPU can be performed.
• By connecting multiple PCs installed with GX Developers to the PLC CPU
or Q-series C24 at the same time, operations such as programming and
monitoring can be performed simultaneously by multiple operators.
Operating the GX Developers using these simultaneous connections can
improve program performance.
• Operations can be performed from a GX Developer by setting the
communication protocol of the Q series C24 interface to which a PC is
connected to "0" with the switch setting using the GX Developer.
(b) Connecting the GOT (Details are explained in the GOT User's Manual
(Connection).)
• By connecting a GOT (graphic operation terminal) to the interface for the
Q series C24 operations such as monitoring the PLC CPU can be
performed.
• Operations such as monitoring the PLC CPU can be performed by setting
the communication protocol of the Q series C24 interface to which a GOT
is connected to "0" with the switch setting using a GX Developer.
(c) Simultaneous connection of GX Developer and GOT
• It is possible to connect a PC with GX Developer and the GOT to two
interfaces of the Q series C24 at the same time. It is thus possible for more
than one user to perform programming, monitoring, etc. simultaneously.
• When the GOT and the PC with GX Developer are connected at the same
time, the two interfaces of the Q series C24 cannot perform an interlock
operation.

POINT
When GX Developer and/or the GOT is connected directly to the Q series C24,
switching settings using GX Developer need not be made to perform access to the
QCPU, monitoring and other operations. (They can also be performed when the
communication protocol is set to "0" by making switch settings using GX
Developer.)
