  1. If it can still help, I ask for some information to the support, this is what they answered me. The MODBUS Set Slave ID is used only when UniStream controller is the slave. In this case you can change the slave ID from the HMI. In order to use that function block, your A parameter is going to be linked to the "SlaveID" tag within the RS485 Modbus Slave struct. The B parameter will be a UINT8 Tag that holds the desired slave ID. Once finished, the B parameter and status get set to 0.
  2. @Ausman, Sorry for all the posts, the page was going to an error when I was submitting the reply so I thought they weren't even send.. Thanks for understanding. @Swervomotor, All that conditions are OK, so I guess I'll have a shot with the support Thanks a lot guys !
  3. Hey @Swervomotor thanks for your answer. Yeah in the help file they specify that the name should be without path and I also suppose extensions. So as required my filename is as simple as it can. (Having an extesnsion or a path in the name should introduce another error code I think) I don't think that this status code error comes from the filename entry...
  4. Hey guys, I'm using a US7-B5-TR22 and I'm struggling with this error that I can't resolve using the Store DTI to file element. My goal is basically to convert my DTI to a .csv file to finally populate a Combo Box. What happens is that I have always the same -8 status which is not documented so I can't know what is really wrong in my program. My E parameter is set to "0" and I tried the F parameter with "0", "1" and "2" none of them are making a change on the issue (In my case I should be using or "1" or "2"). When I use the F = "1", it creates me the .udtf files, but the .csv and .csv.zip are not created. Is aynone has an idea on what is happening or has been through the same status error ? Thanks in advance for your help. Louis
  5. @DanT will do, thanks for your help. Louis
  6. @DanT I found that the CM4 is not internally connected to the same supply network that the PLC, it's separated from the alimentation so I think the 50Hz emission comes from my scope which doesn't have a earth reference. I was thinking about pulling up the HSO-0 with the 10V of the inverter and connect the CM4 to his 0V so I have the same reference but documentation advise me to not do it if I don't misunderstand...
  7. @DanT Yes, I'm able to do it and I can see the change. It seems to be more an electrical problem as when I connect the 24VDC : the 50Hz is add to my signal..
  8. @DanT Hey, I've been checking as you said connecting a 3.3k resistor pull up to my V+ and the scope ground to CM4. Results are that the signal is powered up but I have the 50Hz frequency... I didn't put any load before the scope and I don't know yet the type of inverter that I will command. Thanks for your quick answer. Louis
  9. Hey guys, I'm currently on a project using a US7-B5-TR22, one idea is to use the PWM output to command the frequency of an inverter. I know outputs needs to be enabled as a PWM output so I made a button to activate them when I use the inverter. The thing is that I don't have the inverter here to run some tests, and I wanted to see if the signals were as I wanted them to be. I measured them with an oscilloscope to verify and I can see that the output has the correct frequency, but the signals are about 2mV and of course really noisy. I'm wandering if I'm missing something here or if it's just normal ? In the documentation it doesn't say anything about it. Any idea ? Thanks you guys. Louis
  10. @Saragani yes, this is the way I'm using it. I was telling in the first post that I'm using it the same way in another project but with another host (PLC=Master, Host=Slave) and it works properly but with my new program it doesn't. As I said, I sniffed the serial transmission and the messages from the PLC and the pumps are correct. The problem seems to be the RS485 to USB conversion or the PLC because my registers never get the returned values. (In my first project I didn't had this problem) Thank you for your help. Cheers Louis
  11. Thanks Kikis, It seems that it was the problem! You resolved it. Regards, Louis
  12. @Flex727 FYI I just performed another uninstall/reinstall of Visilogic and I still have the same problem. Maybe a version problem ? I'm using the last one 9.8.80 ? Cheers Louis
  13. @Ausman I did try it as soon as I read your answer and it hasn't changed anything.. @Flex727 It happens with every project yes, and the curious thing is that it started to do this since I reinstall Visilogic the last time. Thanks you guys. Louis
  14. Thanks @Joe Tauser, Yes I'm using the Unistream as a Modbus master, I will hope for an answer from @Saragani and by the time we can resolve this I will simply buy a UAC-CX-01RS4 - RS485 port. Louis
  15. Hey guys, I wish you could help me with this one... I'm currently doing a project using a pump that communicates by Modbus RTU to my US7-B5-TR22. The serial communication and code is done by USB. I'm aware that you recommend to use a Prolific USB to serial converter, I have a FTDI one that worked perfectly in an other configuration but still modbus using serial by USB. Now I can't understand why on my new configuration it fails. I "sniffed" the communication between the PLC and my pump using my computer and a serial terminal, the request of the PLC and response of the pump are correctly sent. The problem is that the PLC doesn't seem to receive or decode well the response because every sessions in my remote slave are failed. Thanks in advance for your help, I attach a piece of code for you to have a look of what I've done. Cheers, Louis test.ulpr
