  1. PLC Unity Pro

    install DTm and try it out - I see no other possibility to check it
  2. PLC Unity Pro

    you are missing all this device DTM's. Just download they from internet and install it.
  3. PLC Unity Pro

    the missed DTM is 140NOC77101 EIP Master DTM  - this DTM is a part of UnityPro and was installed automatically during UnityPro installation. Right mouse click on Q_NOCxxxx -> properties, here you can see which version of DTM was used. Which UnityPro version do you using?
  4. sure, it must be possible to use buttons on HMI. Please read this article: https://www.schneider-electric.com/en/faqs/FA213155/?page=content&country=APS&lang=en&locale=en_US&id=FA213155
  5. no problem -  M340 must be master and ATV71 and HMI are slaves 
  6. Error OBs

    use online help and search for %S and %SW - by using system bits /words you can setup if the PLC should stop
  7. cHud provides right answer. First, after you plug the PLC, you can check if device was recognized by  Windows and starts the USB driver, only than UnityPro will get the connection to PLC.
  8. Error OBs

    OB is operation block. Schneider don't speak about DB, FC and OB.  Schneider speak about EF - elementar functions, DFB - derivate function blocks and data I think  OB Siemens = DFB Schneider
  9. Call SE Support and provide diagnostic file from UnityPro for investigation.
  10. right mouse click on this device and see the device name. Then use google and find EDS file for this device and install it. After that just reopen the application. And read the manual for PRM device - it helps really.
  11. the easiest way is to use EQ blocks and compare actual status word or status bits with predefined values and then trigger the MOVE blocks, which moves 6,7, to to command word.
  12. Hi engMoh, do you use I/O scanner on ATV71?  If yes, then just use WRITE_VAR block to write 2 registers at address 0. The first register will be ATV71 command word (value 16#0006 -> 16#000 7 -> 16#000 F  for starting ATV) and second register will be RPM of the motor.
  13. hello engMoH, just start google.com and type "ATV71 programming manual"  :)
  14. as I know with ZelioSoft v5.1 you will be able to open old applications for SR1, and convert it to SR2. Try to use older Zeliosoft application -> it's for free and can be downloaded directly from schneider web page.  
  15. In worst case you can also take the generic Ethernet/IP EDS, which Schneider Electric  provides for MO580/NOC modules.
  16. Hello PLCRune,   all communication parameters are saved in EDS file. If communication doesn't work then you need to contact the EDS supplier.
  17. in advance use the value 8448 for COMMAND
  18. Well, just take XXMIT block, setup the Communication port and you will be able to communicate via RS485 port.
  19. the connection between UnityPro Software and M580 using Modbus/TCP  Function Code 90. FC90 is private protocol, which description is not available for public use.
  20. you are missing INT_AS_BYTE block. But it was only example from me, it was not exactly 100% what you need.
  21. I used standard blocks in my example and call all variables with their names. 1) ok, first set values to zero count:=0; DO_SOME_CALCULATION := 0; 2)  do a loop for number of elements/characters in your STRING. In your case you have every time 22 characters, so you can just use LEN_ORIGINAL_STRING:=22. 3) you separate every character from STRING - I call it ELEMENT_OF_STRING      as INT 4) you split INT in to 2  Bytes: ELEMENT_BYTE1 and ELEMENT_BYTE2 5) you calculate something that you need with both bytes - I call it DO_SOME_CALCULATION 6) finish :)  
  22. I'm not sure if it something complex or is it to easy :( Your calculation looks like this:  
  23. I hope it will help you:
  24. look Base lib -> Strings, there are a lot of blocks, which can extract/merge etc. the STRING
  25. Sorry, can't see nothing on your screenshot. The address %I2.1.0  means you have an DDI module in in ERIO Rack 2, first place on your backplane, channel 0. But M580 don't support this legacy topological addressing for ERIO. Just click on your DDI module and you will see the DDT structure, which UnityPro assign to this module. In this DDT you will find all your channel variables.
