  1. Thanks Joe T. We would just like our Company Logo in place in the Unitronics Logo and possibly a name of the controller series listed in our sales literature.
  2. I have seen Unitronics HMI Screens out there with a custom bezel made with OEM Markinsg on them. Can anyone tell me where to buy these at? If you could add the approximate price each and minimum quantity, that would be helpful as well. For reference, I am looking for one to fit a 10" Unistream HMI
  3. Has anyone mounted a 2HP Unitronics VFD in a NEMA 4 Enclosure? Most of our applications require a VFD with a NEMA 4 rating. In the past, we have used a VFD that was rated for a NEMA 4 environment and so we had no need to have an enclosure. With the new Unitronics VFD, we would like to use it instead but to meet the area classification, we would need to mount it in a NEMA 4 enclosure and we would like to keep the enclosure size to a minimum. Can anyone tell me what the smallest enclosure size can be if the ambient temperature is about 105 deg. max and there is no cooling fan? The only think inside the enclosure will be the VFD. The VFD I am looking at is UMI-0015BU-B1 with a 2HP Rating
  4. I did ask Stealth about the diver required and he had said " There are no special drivers required for the StealthMOUSE and it just needs 5 volts at 50ma from the mouse port. That being said the StealthMOUSE is only validated for PC use so it could be a compatibility issue with the Unistream controller" I suppose the question now is what the Unistream controller needs to see in a compatible mouse and whether there are additional mouse drivers available for the Unistream Panel. I should mention that as shown in the attached picture, I am running the latest version of Unilogic and my firmware is up to date.
  5. I need to find an intrinsically safe rated mouse with a USB connection for an Explosion Proof Environment. Does anyone have any experience finding one that works? I have used a standard USB Mouse without issue but I have found that when I purchased the mouse fund at the link below, it works on a PC but not with the Unistream Panel, instead, the HMI would not detect it. I am thinking that it has something to do with either the driver or that it is intrinsically safe and perhaps the signal is a bit too weak. Rather than buying multiple mice until I find one that works, I was hoping that someone can point me in the right direction. https://www.spartonre.com/ruggedkeyboards/rugged-pointingdevices/ftm-pm-fsr-panelmount-industrial-pointing-device/ If it is a driver issue, does anyone know if there is a definition of the driver in the Unistream panel that the mouse needs to have that I can then ask the mouse manufacturer if it has? Any feedback would be appreciated.
  6. Sorry DerekGodown, I was unable to get theComm Link to work so I gave up on it. It was an experimental task for me and I did not have a real application so not getting it to work was not a huge problem. I can say that I was trying to use an example program so the example program I was using may have had issues as DanT had mentioned
  7. s.pratt Thank you for your reply. That certainly answers my question and gives me a good path forward.
  8. I just tried forcing the EX-Rc1 into stop mode and the IO COMM light started flashing so I think I misread the spec sheet for the EX-RC1. The blinking Bus COMM light seems to be telling me that the communication to the OPLC is not established. Does this mean that only the wiring could be the problem or is there some other possibility that could be causing the fault? I should mention that I am using only (1) EX-RC1 and according to the wiring diagram for the a CANBus network, there are (2) resistors at each end of the network. At the moment, I am not using any resistors in my network because I could not figure out where to put them and I was not sure if they are needed when only (1) module is used. Is it possible that the lack of resistors could be causing the problem? For reference, I am getting a solid green light for IO Comm on the EX-RC1 and a the RUN light on the AI4AO2.
  9. Thanks Flex727, I found the example file. I had to modify it to only have the AI4AO2 and then I downloaded it to my EX-RC1. I also did the export to Unilogic and then imported back into visilogic like the tutorial and the help files show and it still doesn't seem to be working for me. I do have a flashing green "Bus COMM" light on the front of the EX-RC1. According to the EX-RC1 Spec sheet, this means that it is in STOP Mode. I connected to the EX-RC1 and tried forcing it to the Run mode using Visilogic (Reset options in the "Communication - PC settings"). and I cannot seem to get the light to stop flashing. How do I fix this?
  10. I have an application where the PV moves very fast. When a known disturbance or an anticipated disturbance occurs, I would like to pause the PID loop calculation and lock by CV where it is. I see that Unilogic has a Pause I&D calculation that seems to be the feature to use in this sort of situation but what I am wondering is whether or not I would have better results if I simply de-energized the PID Run Block and then re-energized it when the process is expected to be stable again. In other words, what is the difference in the calculation between simply removing the PID Run command and Pausing the I&D calculation?
  11. I am working on a Unistream Project that will use an EX-RC1 module with an IO-AI4AO2. Does anybody happen to have a Visilogic example File for this configuration?
  12. I have an application where I need to communicate with an ACTech VFD via Ethernet IP using a Unistream based controls system. I am using Output Assembly 100 and Input Assembly 101 to send and receive communications with the drive. At this time, communications seem to be working well with Word 0 of each Assembly but I cannot find out how to read the and write to Word 1, 2, and 3 of each assembly as individual words. When I set the Data Type to INT16, I get 16 Bits that I can read/write as Word 0 and when I change the data type to INT 32, I get 32 bits that I can read&write to but the 32 bits translate to Worda 0 and 1 of each assembly but I cannot fidn out how to see access Words 2 & 3 of each assembly. My questions are: 1. How do I access words 2 and 3 of each Assembly 2. How do I breakup words 0 & 1 which I can currently see as one 32 bit word into two 16 bit arrays so that it is seperated into Words 0 and 1? The manual for the ACTech communications module can be seen at the link below. I could not seem to upload the manual because the file size was too large. http://download.lenze.com/TD/COM__ESV__SMV%20EtherNet-IP%20module__v2-0__v2.0-B__EN.pdf
  13. I would like to suggest an enhancement for the alarm function. Often times, we will have some sort of valve to control such as a gate valve or an auto ball valve which is equipped with open/closed limit switches. The limit switches are almost always tied to an alarm so that when the solenoid is energized or de-energized, the valve is expected to change positions. If the solenoid is switched and the designated limit switch is not made within a short period of time, an alarm sounds to indicate that the valve did not reach its position. At the moment, we have to add a line of code for every alarm to get it to alarm correctly. I think it would be very helpful if there was an option in the alarms for position sensing. This function would allow the programmer to specify an output and an input along with the acceptable time limit that can pass to allow the valve to reach position. If the output comes on and after the set time limit, teh input is not received, the alarm becomes active.
  14. Does anyone know a way to operate one or more remote io wirelessly? I would like to use a Unistream HMI with PLC to control several remote io boxes located within about 100' of each other wirelessly. I am thinking that this canned one using a wireless can bus adapter but I have no experience doing this so I wanted to see if anyone has done this before and if so, what hardware was used?
  15. Eyal, I was testing the Statistics program you made and I found a bug that I can't seem to figure out. The Max Value function seems to work fine but when the Minimum Value is less than 0, it sometimes rounds to 0. I tries to narrow down the symptoms and it is somewhat inconsistent. for example: - When I set the range to 2 and I put a 0.1 on the first register and a 5 in the second register, it works but if I reverse the positions so that the 0.1 is in the second register, and 5 is in the first it does not work. - When I set the range to 2 and I put a 0.1 on the first register and a 5 in the second register like the previous example, it works but then if I change the range to 5, it does not work. Attached are a few pictures to show what is happening.
