    How to get Help with Unitronics Products: Do's & Don'ts

    I'd never heard that term before!!! A quick Google showed that "Support Portal" is more frequently used by a factor of 10--but I have no doubt that "Supportal" will catch up!

    Hello Arvid, As I remember we discussed this case before and the issue was that the connector was not sitting properly.
  4. Hi Priyanka Shahi, Use the information in this link "Unitronics Technical support" on the SQL section. There is a guide written by Unitronics Support that will help you troubleshot your issue,

  6. Look at the data sheet for the -E3XB and make sure you have +24V and 0V present in the right places. It sounds like you've lost one or the other. Joe T.
  7. If you changed the alarm texts in the String library you can also change the font size there. If you have more questions please post your .vlp file. Joe T.

    HELP COMUNICATION RS485

    You need to separate your networks. You have several networks that have multiple rungs, each of which is a logical statement. There's no memory cost for additional nets- move your logic into pieces. You also have rungs that initialize values, such as Main:Net 3 where you write 50 to SI 104. It's better practice to use the power-up value feature for all of this- This applies to SB 168 and SI 108 as well. In net 2, don't put conditions on the SCAN block. Just put a NC of SB 2 on the rail and hang it from that. I would start by talking to one device at a time first and getting that working. Then we can switch between them. We need to solve the Modbus going to 4 and 5. RS485 can be tricky on the older models such as the V230. You may have to play with moving the terminator resistors around or eliminating them. Make sure you have your RS485 polarity right, too. Even though the official Unitronics documentation shows a terminator at both ends, on these old models I have looked at the signal with a scope and found the terminators attenuate the signal too much. Try removing one or both of the terminators while you're trying to get successful communication. Joe T.
  10. Thank you for the reply. I mistakenly attached the wrong image. I actually have SQL server confirmation for the first step. I tried to connect using the IP address of my PC where my local database resides and I believe my DNS is configured properly as I have successfully done setting for email which would not work if I have a wrong setting for DNS. I disabled the firewall on the PC too. I am still not connected to the database. Maybe I am using wrong information in database name section.
  11. 1) You have it configured as MySQL, while it looks like you need SQL Server 2) The PLC doesn't know what is CTP-1. Give it the IP of the computer, (or the Host in case you have the DNS in the PLC Configured correctly) 3) In the Identification Type try using Instance, and then set the instance Name as SQLEXPRESS 4) Set the Database name to be USERTBD 5) Set a Username and Password that are acceptable by your SQL Server. 6) Disable firewall on the computer that hosts the SQL Server.

    You must find the person responsible for passing up on the available term "Supportal" and punish them appropriately yet severely
  13. I am trying to set up the connection between plc and a local database for the first time. Tried many times but an unsuccessful attempt. I think I might be making mistake in configuring the connection parameters in unilogic. In my case I am using SQL server. Can somebody help me to explain the database connection parameters? I have attached my settings below.
  14. Your logic says either I 48 or MB 48 must turn on to latch O 48. If you are activating either of those bits and O 48 is not coming on then you have one of two things occurring: 1) An O 48 coil is elsewhere in the program and is being turned off, or 2) This logic is in a subroutine and the subroutine is not being called by the Main routine.
  15. Hello I am just starting but I have problem with logic I try many times but I can't make logic working the coil is always not set. At test mode you can see red line does not go through coil and on controller no out put led indication. How ever if I force output I can see change on controller led indication
  16. Hey All, often times, when I copy a .vlp file from my desktop to my USB thumb drive I get the following warning; I then copy the vlp. from the USB drive to my laptop or another PC I never have a problem with the program when opened, Just curious what "properties" this is referring to......

  17. i have a machine that work good few month with v570 hmi and snap i/o module V200-18-E3XB and expansion EX-D16A3-RO8 module but now the machine was stoped i mean the i/o of expansion was work corectly but the snap i/o dont work propebly i mean in snap i/o module the analuge input and analoge output work put digital input and output dont work. when i test input/output in info mode they work corectly but in application they dont i dont know what happer
  18. Hello, I use Samba 43 and I change the language of the built-in alarms displays texts , so I had a problem with the size of texts that I translated, I want to know if I can put the display alarms in full screen in order to those texts be suitable with the display alarms?

    Also, you don't need linearization. RTD inputs measure temperature directly, register will have a value of temperature x10 (102 C is 10.2 C).

    Hi Joe, this is program. Thank You Program Modbus RS485.vlp
  22. I just checked, the link works fine: http://forum.unitronics.com/applications/core/interface/file/attachment.php?id=2347

    Your Modbus block is timing out. Take a look at this post- Also, post your .vlp file rather than trying to describe your problem. It's much easier to look at your code. Joe T.
  25. The M-210 was discontinued long ago. None of the currently available software supports it. Contact support@unitronics.com - they may be able to help. Joe T.

    PT 100 SIGNAL TREATMENT

    I'm guessing when you say "a PTC sensor with 2 wires" you are talking about a thermistor. The PT100 input is designed for a 100 ohm DIN RTD - 100 ohms at 0 degrees C, 0.385 ohms/deg C. You'd actually have better luck designing a circuit to provide a voltage or current output based on the specifications of your sensor and the temperature range you are interested in. Joe T.
  27. Hello friends, I am having trouble developing the program for rs485 communication with a danfoss inverter and a softstarter weg ssw07. I am doing a logic of SET and RESET, after communicating with a condition equipment to the next and at the end RESET both. However it is presenting a number 4 and 5 fault. Someone would have a program that could serve as an example for me where I can communicate with several slave, automatically forming a loop cycle.
