SYSTEM CONFIGURATION
(6) Restrictions on online module change (Hot Swapping)
The online module change (hot swapping) using GX Developer can be performed to
the main base unit, extension base unit, and MELSECNET/H remote I/O station
where the Redundant CPU is mounted.
The target modules of online module change are shown in Table2.5.
* 1: When the extension base unit is connected, online module change (hot swapping) cannot be
performed to modules mounted on the main base unit.
:Online Module Change (Hot Swapping) Possible
:Online Module Change (Hot Swapping) not Possible (because cannot be
mounted on a main base unit.)
Refer to the following manuals, for online module change (hot swapping) of input
modules, output modules, and I/O combined modules.
(a) Main base unit where Redundant CPU is mounted
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
(b) Extension base unit
Q Corresponding MELSECNET/H Network System Reference Manual
(Remote I/O network)
Refer to the manual of each module, for online module change (hot swapping) of
analog input module, analog output module, temperature adjustment module, and
pulse input module.
(7) Cables applicable to coaxial bus system of MELSECNET/H Remote I/O
Network
In a coaxial bus system, use double shielded coaxial cables.
Refer to the following manual for the double shielded coaxial cables.
