(7) Connecting the GX Developer and the GOT

MELSEC-Q

(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.)
