  1. Hi all, thought I'd start a new topic where anyone can post a small snippet of a method they use and are happy to share. Just initially a screenshot or link that will get the brain cells of forum participants working hard as to what it might be used for. If it ultimately gets lots of different things submitted, it might become a little clunky and need "linked numbering" here in the first post. To this end I suggest that the time turnaround is a maximum of 4 days between submission and telling the answer, unless it is already figured out by someone. The answer is then given and a new o

  2. Hi all, to start explore I suggest to check HTTP REST APIs for your WhatsApp (meaning some server you address via REST calls on HTTP and it send a WhatsApp message) . For example: https://github.com/sinch/docs/tree/master/docs/whatsapp/whatsapp-http-rest https://www.twilio.com/go/whatsapp-api-90-access-1?utm_source=google&utm_medium=cpc&utm_campaign=G_S_NB_EMEA_Whatsapp_ROE_Emerging_EX&utm_adgroup=&device=c&network=g&keyword=whatsapp integrator&creative=494025116831&placement=&gclsrc=aw.ds&gclid=Cj0KCQjw38-DBhDpARIsADJ3kjkFQR_Wbmbx9w6-1AjPTuw

  3. This is a good suggestion. One of the issues I struggle with when programming with UniLogic (after >12years with VisiLogic) is that there seems to be no effort made by the developers to minimize keystrokes. Indeed, it seems like they go out of their way to increase the number unnecessarily. After spending a day at work with UniLogic, I feel like George Jetson:

  4. This is a concept newer programmers frequently have trouble with so I'm diving into it. I almost never use MF registers in PLC calculations because there aren't a lot of available functions that use them and, as you've determined, they're a royal pain to display in the format you want. The only time I've used them is when calculations such as SIN and COS are needed because angles are involved. Implied decimals are a "sleight-of-hand" programming method going back decades in PLC programming. It requires that you really understand powers of 10 and keep track of them when you multiply

  5. Hi, i try to decode Isakovich Enigma code Then answer for Number 3: Code do sorting numbers placed in MI13, MI14, MI15, M16, MI17 ....... (If we change first Block in row 5 from > to < code change sorting direction). If we change numbers in first row - we change MI used for sorting in this code. Something like C++ for Visilogic....

  6. No. These are for the Unitronics native protocol called PCOM and don't require any additional program changes in the PLC program. Using the PCOM protocol, you can go directly into the V120's memory. Modbus is a totally different protocol that Unitronics supports. It requires Modbus function blocks and configuration be added to the PLC program. The next comment is my opinion only based on my experience- If you don't have a large investment in V120's already, go to the V130. The V120's RS485 port is sketchy - the V130's is much more robust. Plus you can add an Ethernet port.

  8. Ausman's answer is very close to the solution. Therefore, we consider Number 2 solved. After all, thanks to his tips, I found a way to solve this Sometimes, even in simple task with the encoder, you need to show on the screen that the movement is right - left, or up - down. It is also important to know when the object stopped.

  10. Local variable is temporary and does not exist when leave subroutine. Positive/Negative transition should save previous tag state, but it is not possible. B.R.

  11. Baa humbug. I remember using cassette tapes, but others here, not naming names Kratmel, have punched tape! --------------- And now for another piece of silliness tailored to the forum..... A Unicornics programmer goes to the store. (Unicornics 🦄 programmers live in Utopia where all programs work perfectly first try.) Their beloved tells them: "Bring a bottle of milk, and if they have eggs, get a carton of half a dozen." They come back with 6 bottles of milk neatly placed in a spare cardboard box they got the store to give them, and say: "They had eggs." I

  12. The input from the PT100 sensor will be placed in the operand you select in the HW Configuration. It will have a resolution of tenths of a degree (you can select either C or F). The value will have an implied decimal (i.e., 102.6 degrees will have the value 1026 in the integer operand you select). You can then display that on the HMI screen using the HMI Numeric function and selecting 1 decimal place in the configuration box for the numeric variable display.
