You can flash it with SD card. Everything will be cleared to factory settings, including program, passwords and filtering.

Sandisk SDHC, industrial grade works perfectly. Kingstone is also ok, but always fast one and always industrial grade. I've made one time error and used slow SD card on HMI and never again.

Port 502 - is it Modbus TCP/IP?

I'm in process of connecting E200 to FX5U, and it seems that, even with FX5-422-BD it is not possible. Most likely I will change HMI driver to Modbus RTU and adapt both apps.

In fact it could be that you can connect the mouse to USB A (not USB mini), on back, but I'm not sure. It works with barcode scanners and keyboards.

With MR-J5-A, it is not possible, as it is PTO drive. You need MR-J5-G or MR-J5-G-RJ drives in order to have communication with HMI

This program is relatively not simple, it is not to complicated, but definitely requires someone who lives from Mitsubishi PLC programming. If original programmer is not available, I would try to contact Mitsubishi India and ask them for recommendation of it's partner company. For example,  my company, in my country would charge around 2000$, with visit to the plant in circle of 100km to do it.

It is GxWorks3 not GxWorks2.  If I was you, I would call original programmer and pay him to do it.

It is almost impossible that 3 cards have malfunctioning current part of analog output. I presume that you changed the wiring for current mode comparing to voltage mode, and forced M8114 to zero?.  

I already wrote you reply on PLCTalk (https://www.plctalk.net/threads/problem-with-analog-output-fx1n-1da-bd.139641/). Most likely there it is not up to PLC or PLC card. It can be either bug in program or problem with sensors. Why don't you post program so we can analyze it?

It may be also directly programmed in PLC application.

First is to notice that, the machine has to have much more than 10 years, because of A1S.  Second, is from my experience - when I had similar problems in past it was almost always grounding or/and  sometimes overvoltage. My advice is put IT transformer with slightly reduced secondary voltage in front of  24VDC  power supply, change PLC power supply from 230VAC to 24VDC, provide separate paths to PLCs LG and FG (Logic Ground and Fault Ground).

Have you solved the problem? If yes, what was solution?

I would try to check Screen Switching. It is possible that that register is somehow overwritten. For example you have selected D11 as Base Screen, but you have cleared that value at PLC start, or you have registered label wrongly at D10 as double etc.  

You can import it as Part in  Project Docking Windows (usually  BMP, PNG or JPG) and the you can click on imported image select and you can specify transparent color.  

IVRD is used for reading inverters parameters from Mitsubishi VFDs. On other side, Mitsubishi PLC clones, usually do not support FROM and TO, and usually you need to use RD3A command. 

Hubs are Layer 1, switches are Layer 2 and there are Layer 3 switches/routers. I have connected many Q PLCs in my life, and if you connect them directly you need crossover except if your PC has Auto MDI-X, and it will have if it is Gigabit port. If you have problems connecting it with hub, just buy simple switch instead of hub and try it. Today switches are so cheap that it costs you or your company more to write all this posts than to try it. For example Tenda SG105, unmanaged , 5-port, Gigabit switch costs 10$.

I didn't understand your previous question, but I will try to explain. Q port doesn't support  Auto MDI-X so you will  need crossover cable to connect PC to PLC. Switches support  Auto MDI-X, so you can use either straigth or crossover cable. HUBs most likely do not support  Auto MDI-X, so you will likely need to have crossover cable from HUB to PLC.  Remember that idea is to connect PLC Transmit to PC Receive and PC Transmit to PLC Receive.

If you are connecting directly to Q port, than you need crossover, if you are connecting through switch than straigth cable is ok. It could be that with hub you need crossover cable.

Is VNC Server Function License installed? What is value of "Operating priority guaranteed time"?

There is small chance that multimeter or most measuring devices will detect changes with duration of 10ms.

I think that easiest method would be by using PLC inside function of A800, and adding one inductive proximity sensor for 0 degrees. After that everything would be more or less simple math.

Before start try to put parameters below to listed values: 77 - 2 (Parameter writing is enabled in any operation mode regardless of the operation status.) 550 - 5  Be sure that you are in NET mode. Then you can try command: FF0600090001   Also try FF0600080001 because I'm not certain is it +1 Modbus addressing.

For command 06  - Modbus Exception code 02 : "The data address received in the query is not an allowable address for the slave. More specifically, the combination of reference number and transfer length is invalid. For a controller with 100 registers, a request with offset 96 and length 4 would succeed, a request with offset 96 and length 5 will generate exception 02." For command 10 - Modbus Exception code 03: "A value contained in the query data field is not an allowable value for the slave.  This indicates a fault in the structure of remainder of a complex request, such as that the implied length is incorrect. It specifically does NOT mean that a data item submitted for storage in a register has a value outside the expectation of the application program, since the MODBUS protocol is unaware of the significance of any particular value of any particular register." It is 20h o'clock at my country, and I am going on dinner with my wife. We will continue tomorrow, and I will help you.

After that try this: FF06000A0001 000A is 40009
