Appendix 4 Online Module Change Procedure (When Using GX Developer)
Appendix 4.2 Conditions for online module change
Appendix 4.2 Conditions for online module change
To perform an online module change, a CPU module, a MELSECNET/H remote I/O module, the Q64TCN, GX
Developer, and a base unit as listed below are required.
Remark
The Q64TCN with the function version C supports the online module change since it was first released.
(1) CPU module
A Process CPU or Redundant CPU is required.
For the precautions on the multiple CPU system configuration, refer to the following.
QCPU User's Manual (Multiple CPU System)
For the precautions on the redundant system configuration, refer to the following.
QnPRHCPU User's Manual (Redundant System)
(2) MELSECNET/H remote I/O module
A module with function version D or later is required.
(3) GX Developer
GX Developer version 7.10L or later is required.
To perform an online change on a remote I/O station, GX Developer version 8.17T or later is required.
(4) Base unit
• When a slim type main base unit (Q3SB) is used, an online module change cannot be performed.
• When an extension base unit (Q5B) that does not require the power supply module is used, an online
module change cannot be performed for modules on all the base units connected.
(5) Buffer memory areas that can be saved and restored
The following table lists the buffer memory areas that can be saved and restored.
