MELSEQ "intelligent modules" configuration, programmatically resetting the CPU

Hello. This is for the Mitsubishi experts, and thanks in advance for some advice.
The first part of my question is asking for confirmation of my understanding with regards to the so-called "intelligent modules" which in Mitsubishi lingo basically means network and motion control backplane modules. The Mitsubishi Electric engineering tools (GxWorks3, GxWorx2, GxDeveloper, etc.) have special property pages for the configuration of these boards. Also there is an option to configure the board in the PLC logic directly, and this is used when the configuration of the intelligent module needs to change frequently, as this mechanism has the advantage of making it possible the re-configuring of the intelligent module by simply remotely stopping and setting the PLC in RUN again with the engineering tool. For example, the old MELSEC A were programmed like this, and the those old boards had relatively few parameters, such as the IP settings of Ethernet boards.
Now, when the configuration in the special property pages is used, saving the new configuration of the intelligent module and downloading the program, then starting the CPU, won't do the trick, as the configuration is stored somewhere else, so the new configuration of the intelligent module will not be loaded until there is a power cycle or a hard-reset.
I cannot find a way to do a hard-reset remotely with GxWorks3. If there is one my problem is solved, but after years of working with Mitsubishi I have not been able to find one. But I have not asked either, so there may be one and disabusing me of my ignorance will be great.
If the above is correct, then the second part of the question is whether there is a way to programmatically reset the CPU by means of SD register somehow.
I am using a CC-Link IE TSN, and configuring that card by logic seems to be way too complex.

Reply to your firs question is - yes, you can remotely reset the CPU, but you need to allow that option. See pictures below:

For the second question there is option to stop PLC with command STOP, and there is an option to have PLC RUN contact defined, so there is workaround. See manual about command STOP below:

One thing to remember is that many cards have a utility to set them, Not so sure about the FX5 but many others use programs called GXConfigurator so it is seperate software, I know some now are integrated, however, it is no good just downloading the PLC file you must also download PLC Parameters, some intelligent cards can be done in PLC program & there are special registers or bits that can be set & reset to write the config to the card.
Off the top of my head I cannot remember any of them but for example (not a real case) Configure some registers i.e. UG/xxx (buffer memories) set M8xxx then when M8xxx is true reset M8xxx, or eben some of the buffer bits. this means you can on certain cards change the setup without having to reset the PLC. It you certainly need the manuals for these cards as there are often upto a thousand Buffer memories for the cards.

goghie, thankyou very, very much. I tested this while monitoring the CC-Link IT TSN network with Wireshark and I see the communication stopping and restarting. Also, as expected, GxWorks3 issues a communication error.
