Module status setting
The module status setting makes it possible to set the module status such as reserved status and disabled status, interpreting
a configured module in the engineering tool as an empty slot.
The following table summarizes the application of the module status setting.
Status
Reserved status
Disabled status
The change of the parameter settings is not reflected in the module where the module status setting has been performed.
In addition, the following operations have no effect on the module where the module status setting has been performed:
• Setting a remote password
• Executing a program that accesses the set target module
Set the module status as shown below. ( GX Works3 Operating Manual)
Ex.
To operate the system allocating a module on the "Module Configuration" window on the engineering tool, but actually not
mounting the module
• Module configuration window
• Actual system

2.2 I/O Numbers of Modules
Application
• To operate the system allocating a module on the "Module Configuration" window on the engineering tool, but
actually not mounting the module
• To reserve the I/O numbers of a module for future use
• To disable operation of an actually mounted module
Empty
When the module status is set, the set target module is high-lighted, and
regarded as an empty slot.
Writing the module configuration to the programmable controllers allows
operation even without mounting modules actually.
