Today I am back in office and we have a VPN connection to our facility. I modified two text boxes in one HMI screen. However, I cannot download it without a reset. Due to the VPN connection to the facility, TeamViewer is not ready for other connections. When I get this solved, I will ask for a remote session so that you can have a look at it.

Correct, right now everything is back to normal. No reset required after ladder software changes. Completion time after ladder changes below 1 min. A rebuild all (ladder time) takes now approximately 5:35. If it happens again, I will contact you and we can debug it with a TeamViewer remote session. (What is the best way to contact the support? – The page http://forum.unitronics.com/support/ seems to be down) Thanks for your help.

Thanks for your support. Maby I have to increase the RAM of my laptop (currently 8 GB). Do you think that the project is too big or at the limit for the PLC? I did not made a print screen of the donwload dialog. The reset icon was next to all functions I modified. E.g. I changed one ladder element -> in download dialog the reset was required due to this function were the modification was done. In this case only the timers were affected from the memory loss.

I sent you the project via wetransfer. Is there a log file where you can see what function needs recompilation? This would help when the compilation time problem occurs again. There was no (or at least not much) difference in time between compile and rebuild all. (In addition to the compilation time, the PLC needed a reset after small ladder program changes.) All timers pre-set values become zero.

Yesterday I had the same problem with the long ladder compiling time. Each compiling took more than 10 minutes. I rebooted the PC several times and tried to delete the temp files (it is possible to delete files like JET5F11.tmp, however I cannot delete files like ~DF88DF201B390B0325.TMP) and executed the rebuild all function. Nothing was reducing the compilation time. In the evening, I upgraded the software from 1.26.90 to 1.28.26. However, the compilation took also a long time. So I still use the 1.26.90 version. Today the compilation was faster (around 2 min.) Nevertheless, each download could only performed with a reset. Even if just one coil was added. Normally, the PLC needs only a reset if you change something in the hardware or after adding a tag in the data sampler... To make things even more confusing. In the evening several downloads where performed without the need of a reset. (I was not rebooting the PC, I did not executed the rebuild all function) The project file has 19 MB; 54 % of the retained memory are used (manly due to retained DataTable); and 14 % of non retained memory. What can cause the long compiling time? Can I send you the project? What is the difference between compiling and rebuild all? Another strange behaviour have retained timers. The sometimes lose their pre-set value.

Saragani, please can you give me an update to this topic? I always get the message "Change fail, not in range" if the default gateway is not set to 0. With the VisiLogic PLC it was possible to configurate the IP address with a ladder instruction. Each of our facilities has a unique number and according to this number we generate an IP address. So for us it would be great to have this function also in the UniLogic. (It dosn't matter if a restart von the PLC is required) It would also be nice to have the Modbus Communication IP as tag value instead of an static IP. Modifing the CPU IP on the HMI has no affect at all. Is this only possible in the UniApp?

Saragani, thanks for your answer and for your offer to send the project to the R&D guys. We will reconsider using the pre-defined template.

Hi, can someone tell me how to import tags in a project which was created with "pre-defined tags"? (In this case we use the pre-defined tags because we are in progress to convert a V1210 project to the unistream) Thanks!

You are right that USB is not mentioned in this chapter. But as you can see in the picture of the PNOZmulti Configuration tool you can add virtuel I/O's. And it is working perfectly :). To the test configuration: I connected the PNOZ mm0p via a USB cable to my PC (PC is USB Host). Now it is possible to communicate with the mm0p via a termial program (e.g Hterm) as described in the manual. No additional HW needed. The "only" thing missing is the implementation of the "usbser.sys" driver in the unistram operating system ;).

Hi kratmel, this is not correct. You can exchange data (virtuell I/O's, LED Status and so on) over the integrated USB interface even with the standalone device mm0p (As you can see in the picture of my first post). And this is really graet to exchange information with the main PLC. http://downloads.pilz.nl/downloads/PNOZMulti/PNOZmulti_Com_Interface_Op_Man_1001154-EN-10.pdf See chapter 5.3.

Hello Unitronics Team, I tried to connect the pilz PNOZ safety PLC to the Unistream USB Host to exchange data. Unfortunately, this was not succsessful. Windows is using the "usbser.sys" driver to communicate with the pilz PLC (see enclosed picture). I do not know how complex it is to implement this driver in the Unistream PLC. Maybe you can look into it. The communication between the PC and the Unistream with a USB rs232 adapter with the prolific chip is working wonderful :). Best regrads, Daniel

I never got the message "invalid date". However, I have the same thing that the files get saved with a "random" number. Now I'm using the "Filename" tag with a ASCII timestamp.

Thanks for your answers, In the meantime I tried the file on an other Win10 computer. There I could open the file without problems. I will let the customer know that he schould uninstall the Remote Operator and install it as admin. I will keep you informed as soon this was done.

Hi Andreas, thanks for you reply with the feedback from Unitronics. First of all the good thing is that I haven’t seen the overload message for the last couple of days . I’m using the newest Unilogic version (1.23.25) and the SD Management was already configured when the Overload screen appeared. So, I my case I do not see a connection to the files on the SD card… I’m still wondering if there is a connection between the online view mode and the HMI resources?

Hi, I have the same problem that the HMI overload screen appears (mainly when oppening a screen with trends). My observation so far is that the overload screen only appers when the program online view is on. Is there a possible connection between the online view and the HMI resources? On one HMI Screen I have up to 4 trends (only one is a visible in dependace of the selection)... May this be the Problem? However, I also got the overload screen when other HMI screens are opened. Thanks.

Hello, we have a problem with the Remote Operator running on a Win10 System. When you try to open an existing project or save a project the following error appears. The program is executed as Admin. Does someone knows a solution to this problem? Thanks,

R.Mozes, thanks for your support. Your description solved the display problem :). Daniel

Thanks for your answers. I tried out all your suggestions. Unfortuantely, I had no success so far. (@Felx727 what do you mean with re-initialize?) In two day I will receive a new PLC...

Hi, does somebody knows a solution for this display problem? Never had this before... The PLC is a completly new one. I already tried to reinstall the OS. Everything else seems to be ok. Thanks, Daniel

Hello Ofir, Thank you for your response. I am looking for a possibility to import the Slaves Addressing list to the UniStream. For my project an import function would have the following benefit: I have 12 times the same machine part with the same data structure. One time I will fill in the tags manually in the Slave Addressing list. Then export the list to Excel -> duplicate it -> import it back to the UniStream. In Excel, it is easier to change e.g. the Modbus addresses and so on. Is it possible to add 65535 Register and Coils to the slave list or is there another max limit of data?

I'm working on a project in which I have to provide a huge number of data to a upper level SCADA system with Modbus TCP. Is there a possibility to import Slaves Addressing Lists from Excel? (like the export option?) Is it possible to use the Advanced Modbus Functions to provide data addressing as Modbus Slave? Are there any other options to provide the data? Thank's for your help!
