Never heard of a Mitsubishi G-50A, and since you mentioned BACNET, I bet's it's more HVAC than industrial automation. Not likely to find a lot of help on that here...
-
Go look at your EtherNet/IP settings to see if any devices have a red exclamation point on them.

You can't directly. You would need an analog input to read a variable value, and most of those are 0-10V. You should be able to find some kind of device which can read the battery voltage and output a 0-10V analog signal. 4-20mA would also work. You will need an appropriate analog input module for the PLC as well.

What I meant was the being from outside India, I have never seen the product nor do I have access to any information on it. You should contact Mitsubishi within India for more information. That product is not global, so your only help will come from inside India.

Can't help you from over here... that product is only available in India. It's a rebranded device as far as I know.

Not sure you can do what you ask in FX3U. Look at the options in the software to determine what addresses are reserved for variables created without an address, then look at the info that nehpets shared so you know where it will wind up when you do not specify an address.

Not that I know of.

Better option would be NX-Series IO with an EtherNet/IP coupler talking EIP to the CJ.
-
It would really help if you indicate which family of PLC you are using, as there are some differences.

EDS file for an FLnet device? EDS is typically DeviceNet or EtherNet/IP, not FLnet.

Extension modules have addresses assigned automatically, and it always starts at a 0.
FX modules are addressed in OCTAL, so 0-7, then 10-17, then 20-27, etc.
Q/R modules are addressed in HEX, so 0-F, 10-1F, 20-2F, etc.
This is clearly explained in the manuals for the PLCs. You should have reviewed this information before assuming what addresses would be assigned. You will have a lot of work to clean up anything you wrote before understanding this.

CX Programmer 1.2 is from around 1999. No update capability... Current CX-P is like 9.76 or something.

Where do you see it listed as incompatible? In the manuals it clearly lists Windows 10. I doubt they have any plans to test it for Windows 11. But I can say I run Windows 11 and have had no problems running CX-Programmer.

realpars.com, udemy.com, plcacademy.com, and almost every PLC vendor has some free online training materials, even if they are pretty basic.

There is also a seconds to time function, SecToTime, if you don't want to use nanoseconds. The IEC data type TIME is something many HMIs can show but cannot input.
The motor encoder makes 8,388,608 pulses per revolution. To work in Inches, select Inches and then put in the number of inches of travel that makes on your conveyor, and all motion and speed will be scaled into inches. How far the conveyor moves for one shaft rotation should be documented by the company who made it. You don't need to use the gearbox feature in here, you can always do the math and determine what 1/8 of that rotation is since you said an 8:1 gearbox.
It's all a matter of entering the right numbers, pretty simple IMHO.

You can use TP instead of TON so you always get the same length output no matter how long Start_motor stays on (or doesn't).

can anyone help me how can I add NT631C V4.2 in PT list as it is missing and I think the problem is that only 4.1 version is there in PT list
I have tried adding registry files but thats not work for me
any other suggestions and solutions please
Are you sure you have a new enough version of software?

I have different experiences as you. The forums are usually meant to help users to solve their problems FOR FREE.
Help with problems, not do your engineering and write your program for you. You didn't mention a problem, you asked someone to write a program... If you have a question about your code, show us your work and we can assist. But system integration costs money.
Best of luck.

How does the software send/receive? What protocol? I've never heard of that software.
-
The robot is communicating over wifi, the PLC is wired, are you sure the Wi-Fi IP address is in the same range as the ones on the controller and laptop?
-
Is the IP address on your laptop set in the 192.168.250.x range like the PLCs?
Are you certain the IP address on the new laptop is not the same as another existing device?
-
The 9 pin port is RS485, so at a minimum you will need an RS232 to RS485 converter, if you can even program it that way.
I've only ever programmed those over the Ethernet port, and that was 2 decades ago.
-
Not possible.

When you make variables in the HMI, you can assign them a default value to be applied on every power up. There is an option in Synchronize to also initialize the variables. That is why you see the dialog.
If none of your HMI variables have default values set, then it does nothing.

I think it will be just like working with USB to serial adapters. Some of them do not implement the entire control set, and things like CTS/RTS are not always connected. I've used a dozen brands of USB to serial adapters, and of those, only 2 worked on all the PLCs I worked with. Like pturmel said, it comes down to seeing how the wiring is crossed between the two devices.
