    UniStream & RS485

    The CPU hosts a RS 485 port that you can use for communication. This port is available for use. You can set it up as a configuration in the process tree on the right hand side of the software. It does not require configuration function blocks such as VisiLogic would. I hope this helps to clarify.
  2. Hi Don, This does not check for this as it is a legal condition. if you are interested about one unique bit you can select (Ctrl+F) enter the bit or coil in question and confirm it is not present twice in the same routine shown in the results in the output window at the bottom of the software. Hope this helps

    Problem with M91-2-UA2

    Hi Stavros, It may help to ensure there are no power-up values assigned. Another key is to check to see if the RTC (real time clock) has been reset. If this is the case and it is resetting you may wish to contact Support@Unitronics.com for further assistance.
  4. Hi James, It is difficult to tell from the screenshot alone, if you were to provide the application to Support@unitronics.com, Our technical support would be happy to look into it for you. Mike
  5. Hi Luk, A counter counts rising-edge pulses. When the accumulated number of pulses equals the counter's preset value, power flows through the function and the counter bit turns ON. Once the preset value is reached, the counter bit stays ON until it is reset via a Reset Coil. This also initializes the counter value. It does not hold retentive values as a MI or ML would. This is why they are not listed to be used. Mike

    USB Storage

    Hi Russ, There is no method of performing this action to date. There is no USB connection on the PLC The USB to serial converter is used to communicate from the software to the PLC and only operates well as there is a driver contained within the software. Therefore if the same concept were applied to saving to a USB like it were an SD card, this cannot be performed as the PLC does not have the driver or the capability to support the USB to serial converter on its own, nor does the USB have the ability to host software. This is why any information exchange uses a PC or other process/software driven operation other than standard flash memory like an SD card. This can be performed on the UniStream controllers using the USB ports. Hope this helps to clairify Mike
  7. Hi Steve, I have seen similar conditions in the past, This sounds to be a ground condition. Please ensure the TC is connected to ground at the signal source. Please ensure the furnace is connected to ground as well. In the past I have seen a similar condition with a TC in a motor case, after further examination there was a ground strap that was loose, causing the condition. It may be helpful to test with a different TC to confirm it is the field wiring and not the hardware. Thank you
  8. Hi Mk5s, The jumpers can only be checked visually. there are no system bits or operands to confirm the setting of the jumper. It is best to confirm with the instillation guide for that PLC
  9. Hi Dave, I have included links to the specification sheets for the SM43 units. These can be found in the Support section of the Unitronics webpage under "technical library" http://www.unitronics.com/docs/technical-library/specificationssm43.pdf?sfvrsn=0 (SM43-J-R20) http://www.unitronics.com/docs/technical-library/specificationssm43-jt20.pdf?sfvrsn=0(SM43-J-T20) Thanks
  10. Hi Flex, I do not think I have the ability to change specific settings, but from what i can find there is no reason you should be getting blocked from uploading an image. I have had no trouble so it is not a site condition. It seems to be specific, we will need to dig deeper to determine the condition.
  11. Hi Flex, If you want to post an image then you should navigate to the gallery and use the upload option in the gallery.
  12. Hi Flex, If posting an application to the forum you will want to use the navigation plane at the top of the forum that is labeled downloads. This will allow you to upload your file to be available for download by other users of the forum. This is what i do when i post a file. Thanks
  13. Hi Flex, You have 2 options, you can Download the previous version and use Version Swapper. https://unitronics.exavault.com/share/view/4lk6-5yavn87c You can also update the application the the newest version and use a UniDownloader file that has the firmware included(OS,BIN,Boot) http://www.unitronics.com/support/webinars/downloading-utilities Either method will be sucessfull. Mike
  14. This seems to be a unique condition. You should contact Unitronics Support or the OEM to proceed. Support@unitronics.com
  15. Forgive me the keys you want to press are the <i> and Esc key. Sorry for the initial error.
