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.

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

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.

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
Michael_P replied to russedwards's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
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 -
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

Samba
Michael_P replied to DaveE's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
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 -
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.

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.
