Not all USB to RS232 converters work with Unitronics - you need one that uses the Prolific PL2303 chip. Unitronics offers a converter with part number MJ10-22-CS35. What kind of converter do you have? Joe T.

Those were the exact thoughts I had. I am not familiar with BGA reballing so I Googled that up. Wow - that is not a skill I have. https://www.youtube.com/watch?v=EjAdz8jQL4k Joe T.

I would be most interested in what you have to share on this. Joe T.

It worked properly for me. I did find that you had your baud rate set to 19200 in the COM INIT block where your comments said it should be 57600. Joe T. MODBUSmaster JT.vlp

If you are able to successfully read that is a good sign. Upload your program so we can see the rest of it. Joe T.

Just to be clear - you have a static IP assigned to your account on the Internet side of things, right? Are you using a cable system, DSL, fiber, or cellular to get your service? If you don't have a static IP on the Internet, you will have to configure your router to use a Dynamic DNS service if it is capable of that. Joe T.

Here's what the official descriptor says: I honestly don't know on the JZ10. I don't use the Jazz series very often. Joe T.

It is good to be loved. 😍 There is a Drum function in Jazz. It's one of the internal functions without blocks but it's well-documented in the Help and it has its own configuration on the Project Tree. I agree that this application would be well-suited for that. @zavis- if you want to have a go at this and upload your PLC program we can be helpful. I used to teach the State Machine method on Vision PLCs when I still did a PLC class locally. All the students wanted to learn Allen Bradley, but the local Electrical Board didn't want to pony up the money for trainers and AB doesn't

The full 9.8.65 is still listed under "Previous Versions" - https://www.unitronicsplc.com/Download/SoftwareVersions/Visilogic/VisiLogic_9_8_65.exe I would just follow the re-naming instructions to use the Swapper and download and install this. Joe T.

Look at C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\ladder\V1040 - Alarm Example.vlp Joe T.

I tried putting a Positive in a function used in a UDFB and it worked. Can you give a more specific example? Joe T.

It depends on the database version, which is not widely published. Can you open his .125 program in your .106 installation? Joe T.

@Cara Bereck Levy Take a look at this post, especially near the bottom- If you look at the post reference chain within thus post you'll see that the question of reading floating point values from energy meters is a very recurring theme. It's a common occurrence for word order is always backwards from what Unitronics is expecting. Ask the Creators how hard it would be to add a new type of Operation to the Registers tabs for function 3 and function 4 - "Read Holding Registers Swap Words". If you look at the Official Modbus Protocol Specification- https://modbus.org

I'm guessing you're using a -TA30, not a -T30. I don't have one of these in front of me to test, but if it's like other Unitronics analog inputs the common is not isolated and it's expecting a sourcing signal. Your SMC is a sinking analog output, which means it's expecting to get it's power from somewhere else. You'll need a loop isolator to connect this to the PLC. Joe T.

Don't forget SI 101 packet timeout. It defaults to 2 (200 ms). Set it to 10. Joe T.
