  1. Nothing to do with controllers or odd misinterpretations of binary digits, but one of the funniest things I've seen in a while. Put down your coffee. You have been warned!

  2. Hi everyone!I'm developing a project with UniLogic v1.25.61 for the UniStream USP-104-B10. I would like to know if someone have linked UniStream with any API to send Whatsapp messages instead of emails or SMS. If not, can anyone suggest where to start exploring? Thanks in advance! Gonzalo

  3. 1. Delete MI 8 power-up value -Sample Time. It will be calculated by Autotune. 2. Water temperature range is 0 to 100. It is recommended to set: - MI 9 =0 (0.0) - MI 10 = 1100 (110.0) 3. MI 0 show temperature in 0.1 C/F. 4. Change User Set point MI 47 format to 4.1 Entering 55.1 from display will be represented as 551 in MI. 4. Use MI 47 instead of MI 3. 5. Sample MI 0 in 4.1 format. 6. Delete nets 2 and 3. Test it.

  4. That's actually a program crash within the PID server. It's been a long time since that module has been updated. What happens if you Auto Tune the loop without it? Joe T.

  5. You can't compare an MF to an MI. I don't know why it let you enter that. You'll have to convert the MI to an MF register. Joe T.

  6. Yes, there is a difference. You don't need the additional SET coil of MB 9 on the float block. The output of the instruction is stored in MB 9 as you've shown. Your logic as written will always set MB 9. Your INT compare is correctly done. Joe T.

  7. I'm assuming you're reading the same tag from UniCloud as you have mapped to the the display that the VNC client is showing. If so, send this one to support@unitronics.com. Joe T.

  8. The current version of UniLogic is 1.31.146. Download that and update the OS on your PLC. You should be getting a free trial UniCloud account. It should work after your PLC is updated. Joe T.

  9. Gili, if you haven't found it yet, there is a wealth of information in the Help files. In your case it can be found under the Contents tab, shown as HMI Displays. Many users completely miss the existence of the Help files, not knowing how useful they are. cheers, Aus

  10. Just place a Numeric variable on the HMI screen and check the box for Keypad Entry.

  11. I remember seeing a memory device similar to this at my first mentors workshop back in the mid '70's It was an archaic thing at that point, but I seem to remember that the memory bank included inductor/cap/resistor circuits that "remembered" their last logic state, and transferred that with some sort of FIFO logic. Crazy thinking back in those days, but we wouldn't be where we are without it.... 😵 Now, what happens when you throw one of these in front of a young'un? I still have my first TI-35 scientific calculator that I bought in the '70's....

  12. Thanks for the feed back guys! Ausman, yes it's a great feature and would be really nice for something like a remote installation but in this instance I don't believe it's very practical with the large data requirements of this business plus 4G static IP addresses are becoming increasingly difficult these days with Telstra no longer issuing them and the specialist ISP that do provide them are very expensive on the data front. Joe, this is exactly how I imagined it would work and fills me with much confidence! looking forward to giving this product a run.

  13. +1 I have looked at this pulse on a scope. For a 24V DC control signal, it varies between 200 and 700 volts in amplitude (depending on the size of the coil) and is 1-5 microseconds wide (that's 200 KHz to 1 MHz). If you clamp the flyback pulse all the way back at the output module, then all the wiring between the device and the module becomes an antenna, transmitting this garbage into your other wiring.
