8.3.8 Replacement of Modules Mounted to Extension Base Unit
A module mounted to the extension base unit can be replaced online using GX Developer
during operation of the system.
The following shows modules where online module change (hot swapping) can be
performed using GX Developer.
• I/O module
*1
• Intelligent function module
*2
(Analog module, temperature input module,
temperature regulating module, and pulse input module)
* 1: For changing modules online (hot swapping) using GX Developer, refer to the following manual.
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
* 2: For changing modules online (hot swapping) using GX Developer, refer to the manual for the
intelligent function module used.
POINT
1. When connecting the extension base unit, use the Redundant CPU whose
first 5 digits of serial No. is "09012" or later in both systems. In addition,
connect the redundant type extension base unit to the first extension stage.
2. The intelligent function module other than the analog module, temperature
input module, temperature regulating module, and pulse input module are not
compatible with online module change (hot swapping) using GX Developer.
For the intelligent function module which is not compatible with online module
change (hot swapping) using GX Developer, turn OFF power supply of the
power supply module before replacing modules.
