  1. Hi, I try to it look like useful.... but some Java implemented app and many other specific application was closed or crashed, sometimes even if i try to sw to another folder. Deleted renamed folder - all restart without problem. I spent some time figuring out what's wrong. One of the programmer forum participants gave a hint ... So you have to be careful using this "magic wand". :)
  2. Maybe only language can be changed via String Library from 1536 to 1584 rows. But appropriate font with the same as default font parameters must be installed.
  3. Hi AlexUT, I know about card and controller capacity limitations and format limitations. Especially about Siemens :) There will be a problem with the small capacity card in the future. It's just a matter of time. Last week I was looking for a new CF 128MB card for the machine (2009). It must be formatted only in FAT. It's now impossible to find them smaller than 4GB. The Unitronics controller now meets the requirements for card use, but 1TB cards are already flooding the market. Therefore, the search for solutions for the use of new large memory cards in control
  4. This is my simple protocol configuration for zebra motorola LS2208 barcode scanner. You can use numbers placed in vector copy MI150 (in my sample), if you scan another barcode it will be replaced (MI50 to MI150 copy vector) P.S. But maybe moderator can place this part of topic separately.
  5. Hi, As decleared in https://unitronicsplc.com/wp-content/uploads/2015/12/IO-RO8_L-5408-0051-9.pdf I0-R08 has 12VDC option ----- I0-R08L. The main issue with expansion = P-ON condition. Both - PLC controller and EX-A1+IO-R08 IO must be powered from the same power supply. By the way if you power M91-2-R1 and EX-A1+I0-R08L from 12V 1. Both the OPLC and the EX-A1 must be connected to the same power supply. The EX-A1 and the OPLC must be turned on and off simultaneously. 2. The 12VDC power supply is supported by versions V2.00 (EX-A1) and later.
  6. It may be necessary in the future to allow the formatting of large cards into a small capacity (limit its capabilities to FAT32 accordingly). If it is possible to do it at all with new large capacity cards. Alternatively, add an card format option to PLC info mode (uni app) functionality. P.S. It has been done in drives that replace 1.44fdd. They format the flash media themselves into 100 small virtual disks.
  7. You can use delta software http://www.deltaww.com/services/DownloadCenter2.aspx?secID=8&pid=2&tid=0&CID=06&itemID=060201&typeID=1&downloadID=B2+Series&title=B2+Series&dataType=8;&check=1&hl=en-US and try to check data flow from and to drive via SAMBA port monitor in SAMBA info mode. But i do not know about delta software connection to the drive. If it is via RS485 - you can use SAMBA for monitoring.
  8. You can scan barcode by Protocol FB. Scanned barcode is replaced by another one in buffer if you try to scan another barcode. There is several options in this process: 1) Barcode 1 = Barcode 2. User can scan barcode 1 (or barcode 2) two times and it is wrong solution. 2) Barcode 1 not equal Barcode 2 but these two barcodes is an assembly unit - you can scan it and find a row in DTI where another one barcode is present. 3) Use two barcode scanner with different positions (stationary) connected to different com ports. Parts scanned if it fit correctly. 4) Barcode
  9. I think that to communicate with the instrument you do not need to worry about the checksum when receiving messages. The key is to make sure that the entire message is received (checksum as a number and also {} as characters) and that each part of it is correctly written to a variable. You will be able to transmit all the values you need and then you can start experimenting with a checksum to ensure a guaranteed transmission.
  10. I used this little samle for read non standard protocol from power supply. Message with different length easly read in to MI vector. PROT_FB.vlp
  11. In one of my projects, I measured the length of the material using an encoder. The customer initially wanted to print the measurement results on a thermal printer (Zebra GK420d) locally and be able to view the status remotely over the network. However, after buying Samba SM35-J-T20 and conducting tests, he wanted to implement reading the order number using a barcode scanner. I could not install the optional com port because it was replaced by a network adapter. After testing with the printer, I found that it only needed two wires GND and TX. The barcode scanner (LS2208 RS
  12. Is it RX-TX cable connected properly? In Example you can see 570 modbus loopback test project with modbus setup for one V570 with two rs232 port connected TX-RX, RX-TX. Use this example for test connection with two device. Both of them can be master or slave on different com port.
  13. V350_PID simple demo.VLP V120_PID_motorized_valve_output_with_physical_feedback.vlp in Examples
  14. It is one more testing method for your USB-to-serial adapter. Please download terminal program (like hercules ect...). Plug USB-to-serial adapter to USB port and temporary connect 2 to 3 pin together. If you send some characters from terminal you will recieve it back if this adapter is operational. Then you can test wires that go to Jazz PRG at the same way. (connect RX + TX line together by wire without Jazz PRG).
  15. Please read this https://unitronicsplc.com/Download/SoftwareHelp/U90LadderKnowledgebase/Communications/Direct_Communications-_PC_to_PLC.htm You can see that jazz PRG use pin 1 and 6 for PWR. Maybe USB-to-serial adapter do not offer correct power supply to Jazz PRG. The connection may start and disappear due to insufficient power to the adapter. USB-to-serial adapter usually uses a low power converter based on the capacitors to generate output signals, so it may not be able to power the Jazz PRG programmer. Please see this and use more pin connected to PWR line

    20.20.20 20/ 02/20 ???? It's a pity, we have only 12 months on Earth Maybe we lost 20.20.20 02/02/02 or 20.02.20 20/02/20
  17. Thank you Joe! :) is used for isolate board and fit board to Jazz PRG dimention. You won't believe it, but a broken arduino + chip for correct galvanic isolation works as a programmer or PC232 port. The main task was to create a CNC machine based on Jazz and the free Arduino GRBL CNC conrtoller based on a stepper motor. It installed to Jazz like JazzPRG. It had to perform only two standard movements but with a complex 2D trajectory. Everything works ... Jazz 10 replace original old puter and ISA CNC card in it!
  18. I tried to research this port and the original programming adapter for my own needs. Making your own is probably possible (and I even managed to do it with the USB interface- on foto), but there are two major problems - there is a 3.3 volt communication port in the PLC that requires a mandatory galvanic isolation that is in the original adapter. Therefore, I recommend listening to the above. You should use the standard devices listed in the topic for programming this PLC.
  19. This is string library and String from library in object text proprties. Please read visilogic help. But you must use HMI---Font handler if you need specific language in string text (like cyrilic).
  20. Good advice! But... Generally operand export must be performed when setup and fine tuning for all parameters is done. It is the last step in my PLC programming job. That is the main problem : sometimes you can not know correct value for all operand when project is downloaded to PLC. And i think - PLC operand export is not useful integration option (p.1 ) . But in Properties--Messages for ask or not ask user to import operand values from the files after download project is good idea. P.S. Operand description and operand value is exported separatly.
  21. It is good if you can change CANopen status of drive. In my first CANopen project i try to read or write only one parameter. The real problem - understand how to calculate correct mapping for all data. This problem present for drive side and PLC side. Better way is to use default drive side mapping and adapt PLC mapping in the same way. After this model is operational - you can change driver side CANopen register configuration and test nonstandard mapping. Another topic with my first steps project. You can see how to use struct for send TPDO and RPDO You must
