OVERVIEW
(5) Indexing in the range of 32-bit
Indexing for entire area of the file register is possible by expanding the indexing range
to 32 bits.
(6) Communication using built-in Ethernet ports of CPU module
The Built-in Ethernet port QCPU can communicate with MELSOFT devices and/or
GOT using the built-in Ethernet ports of the CPU module.
Features of the functions using the built-in Ethernet ports of the CPU module are
described below.
(a) GX Developer/GOT connection (
• The Find CPU function makes it possible to find the Built-in Ethernet port
QCPU connected to the same hub as GX Developer and displays a list.
• MELSOFT connection allows access to CPU modules on the network, such
as internal LAN, via routers.
(b) GX Developer direct connection (simple connection) (
• When connecting the Built-in Ethernet port QCPU with GX Developer, the
direct connection (simple connection), which connects them using only one
Ethernet cable (not using a hub) is available. The direct connection enables
communication with only specifying connection target. IP address setting is
not required.
