Right click on it and use the find feature to see where it is being referenced.

I believe support@unitronics.com can roll back the database of the project if you don't want to use the beta version email them a copy of the program.

Another option is to send a compressed file to a SD card installed in the PLC and then trigger it to update the program from there. We typically do this if we are not having a tech on site(sales reps don’t count). As we have a copy of the current program in the SD card the rep can test and if there’s a problem they can revert back to the previous program and NOT rely on the Ethernet connection to stay up.

Yes you can convert .udt files with the SD Card suite. SD Card Manager is the utility that you would use.

Look up the data export utility. It will let you pull a data table from a PLC to a PC and convert it to excel format. You need a PC with excel on it in order for it to work.

Is the tcp scan located in a sub routine?

I’ve had a similar issue with a long drop. I accidentally used stranded crimp connectors instead of solid. It worked on the tester but didn’t work connected to anything else. Re crimped with solid crimp connectors and worked fine.

Can you post your code?

When you say configured did you do both the hardware(jumpers) as per the installation guide and the software in Visilogic?? Not sure which model you have but id you didn't open the unit up and move jumpers your working with a digital input. Install guide links: https://unitronicsplc.com/wp-content/uploads/2015/12/SMXX-J-T20_R20_DOC17015-A4_02-15.pdf https://unitronicsplc.com/wp-content/uploads/2016/07/SM35_43_70_RA22_IG_2_16.pdf https://unitronicsplc.com/wp-content/uploads/2015/12/SM35_43_70_TA22_IG_2_16.pdf

The jumper setting are in the installation manual.

Why not set up a dedicated VPN for the PLC and remote user?? You my have to invoke the customers IT department but that would be secure and they may already have the infrastructure in place to do it.

To get around the touch buttons activating you could add code to load a blank display in net 2 of Flex's example and then in net three add a load last display This would cause the sleep screen to have no touch properties to affect your process and once the screen is touched to wake it up cause it to load the display that was last up.

Your both constantly calling the main display which is what is causing the screen to flicker. See net 1 in the original program, every time the PLC scans the logic it is going to load the Main display. (In a Vision unit we are talking every 4-5 mS) You can remove this net. Also while net 2 works you should have it broken into 4 separate nets. Nets 7,9,11,13,16,18 in the Main routine should also be separated in to multiple nets( you can get abnormal operation with the way you've done it) I didn't check the other subroutines but any where you've done something similar should be broken in to multiple nets. And why are you calling the displays from the ladder using MB's linked to touch properties?? If you click on the Links & Jumps tab while editing an HMI you can put your display calls there and not have them in your ladder.

Check your code and make sure your not constantly calling a load display function. or post your code so we can look at it.

Are there forces in place on those inputs??

I know it will work strictly as a serial link however not sure about going Ethernet from Remote operator to serial at the PLC. To clarify you are set up like below correct? PC ->> Ethernet ->> TCP/IP - RS232 converter ->> PLC Remote Operator is going to ask for an IP, Port and PLC name in order to communicate, over Ethernet, while for a serial link all it is going to need is the Baud rate. While the converter will probably translate everything in the TCP communication from Remote operator there will be a lot of extra information going to the serial com port on the PLC that it probably won't know what to do with and more than likely you won't be able to establish communication. If you have all the components try it and see what happens, If not and you still want to use remote operator then either look at upgrading to an Enhanced Vision like a V130 which can accept an ethernet card, or you'll need to look at two TCP/IP converters and set it up something like PC ->> RS232 converter-TCP/IP ->>->> Ethernet ->> TCP/IP - RS232 converter ->> PLC

If you know the protocol structure you can most likely use the protocol send and receive to communicate with the serial devices on RS232/485.

I loaded them into a V700 and can send a serial command that my PC will see in Hyper terminal. I've got three subroutine calls in the main routine and then changed SB1 in both the Initialize and send subroutines. I suspect you've got an issue with how the subroutines are being called, but can't help as you didn't provide the full code. Are you using conditional subroutine calls??

Can you post your code??

I think it would be around V9.3.1 or V9.5, contact support to find out for sure

Use a positive transition contact -|P|-

Check the Battery. SB 8 0=good 1=low.

Right click on the exe file. Properties then look at the compatibility tab there should be a check box for run as administrator. Check it and you will still have to select to apply it for all users.

https://mikrotik.com/product/RBmAP2nD is one we have a couple customers using. You will want to download winbox to configure it rather than using a terminal.

Look at the installation guide. There's a jumper you need to move.
