It's called a variable.

What you called HMI blocks are called function blocks, they have absolutely nothing to do with the HMI. On the second picture, they are timers.  On the third pictures, compares and timers.  They are not 'instructions for the HMI', if you could read you would see the comparison signs. And you do not program the HMI in the PLC. The HMI can adjust a value in the controller's memory, but the program for the HMI resides in the HMI.  

What are you talking about HMI?  You never mentioned an HMI.  Or anything involving passwords.  Or scripts.  If you have questions, you need to type them into your message.  We are not psychics here.

You right click, "Coupler Connection (USB) and there is a submenu that comes up where you pick 'Online'.  Pretty straightforward.  Works perfectly for me.  

You need to look at the FX5U Programming Manual and understand the different memory areas and how they are labeled in Mitsubishi.   %MW is memory words, so like D registers in Mitsu. %SW is system words, so things like diagnostic data.  Old Mitsu FX products had these in the higher D registers, above 8000, not sure if the FX5U is more like Q Series and has a separate area called SD. %M is typically bit addressable internal memory, similar to M addresses on Mitsu. %I and %Q are inputs and outputs... Mitsu doesn't prefix those with any letters, they are based on the module layout.

Sounds like a bug, did you contact Omron and ask about it?  I have saved countless safety projects, but I do not use the version control feature.

Check the error message at the exclamation point.  I highly doubt you running out of I/O power (PF0630) because the software cannot calculate how much you plan to use.  I bet you are low on control power (PD1000) used to power up the modules themselves.  2 different power supplies, 2 different modules.  I know for a fact that Sysmac Studio takes into account the DC bus power supply.  

Sure sounds like an issue with cabling, such as grounding or electrical noise.  There's no other devices on the network like an Ethernet switch or PC right?  EtherCAT uses Ethernet cables, but not Ethernet devices.  Make sure you are using shielded Ethernet cables, though I can admit I have use 10m unshielded cables without an error.

I have use Soft-NA for months and powered off PC many times, never had a program corruption issue.

This post is from 2004, from a person whose account no longer exists.  

I don't think so.  I think the barcode function was only for the RS232 serial port.  But have not touched on in years, so can't say for certain. I think the USB ports are for keyboard, mouse, flash drive only...

Nobody here can share the method to hack the HMI, because discussions of bypassing passwords are not allowed here.  You agreed to that in the terms of service when you created your account.   I have closed this topic.

RWr is read word data, RWw is write word data, they should definitely NOT overlap...  But both can be in any memory area...

There's no right or wrong way to set them.  They are setting where the data will be found in the controllers memory.  You can use any memory area you like. B is bit based, so it makes referencing the individual inputs and outputs easy. W is word based, so it would occupy words of memory and individual bits could be addressed with a period, such as W10.0. Both B and W address in hex, most people use these for CC-Link because of its default allocation size being 32 bits in and out per station... so station 1 would be B700-B71F, and so on...

Pretty sure the NJ and NX don't have control words anymore, and there are settings in the module when you right click on it and select Edit Unit Operation Settings.  Then variables get mapped to the module's data in the I/O Map window.

I don't know any safety CPU with an analog input.  Analog signals are not typical safety devices.

Adding more devices to the network will use more addresses in those ranges, and I suspect the issue is RWr will overlap into RWw.  They should be farther apart. Your new device cannot be set for a node address under 16, those are all in use.  Look at the second number in the station number columns, the first is simply a device number, the second is the first station number.  Some of those devices occupy 4 stations.  Stations through 15 are all used.  

Almost every single QCPU ever sold is in Q mode.  The QCPU A Mode thing was a very limited sale option that programmed like an A Series.  I think the Mode light would be amber or red if it was in A mode, and normally green.  But it's been a decade since I've touched one of these CPUs. QnA Series is legacy product, came between A Series and Q Series.  Been obsolete since 2005.

Might be possible to use non-safety devices, but sure not smart.  You need to be looking at G9SP.  

Haven't seen that behavior... but then I haven't done many online edits recently either.

Sounds like my company-issued P53 setup as well.

Aren't GSD files for Profibus?  Where would you use that in Sysmac Studio?

Hasn't closed all tabs when switching devices in a couple years... what version are you using?  I have noticed some tabs, like HMI Variable Mapping, do still close when changing devices, but all tabs do not automatically close like they used to.

Just bought some i7 (11th gen) with 16gb RAM and 512SSD

It is certainly NOT a shortcut!  If you look at processing time on the newer PLCs like NX and compare them to the older ones like CX, you can do in under a millisecond what used to take 30-50ms.  There are blatantly obvious benefits to using a standardized chipset.
