I am distributor of Unitronics too and I had to improve functionalities to Unitronics thanks to other products: Datalogging USB with Fuji Electric Hakko Electronics with the protocol of Unitronics. Advanced Web Server and UMTS modem with eWON modem router. I'd like the Next Generation of Unitronics will have these but I sold a lot of PLCs without them. eWON have a good solution for "scada" web and it's very easy to read data from Unitronics with Modbus Protocol.

There are examples of MODBUS TCP in the help of Visilogic, I think for V280 but it is easy to convert to V570

The only way to do similar something is with subroutines. If you look for this topic in the forum we were asking for them for centuries maybe next generation...

No, I want to write a .vlp application and a HTML with only a link to the CSV file.

What about this rugged BT to Serial RS232/RS485: http://www.connectblue.com/products/bluetooth-products/bluetooth-devices/bluetooth-rugged-serial-port-adapter-rbs433/

I see, Red Lion have three drivers when Unitronics PCOM have two ways "ASCII" and "Binarian". Anyway, does work @rantonides?

After the FB SD Utility Delimited Line you can use the FB Str. Replace to put comma instead of point for CSV.

OK, I have never had problems with SSR of ERO ELECTRONIC, CONTINENTAL, FUJI ELECTRIC. The end customer have this kind of low cost SSR but they works well with Toho Controllers. Well, I think the idea of the power suply to solve the drop in voltage of the cheap SSR will be the solution.

I don't understand you, the protocol of the document is PCOM ASCII, Either M90 or Vision. Red Lion just says that Verified Device was a M90-19-B1A

Carlo Gavazzi: RJ1P23I50E RM1E48I50E SSR doesn't work with 4 - 7.2 mA

Because the Scan time is not a fixed time the ramp will not be accurate.

I have some problems with analog SSR (Celduc, Carlo-Gavazzi, etc brands) when I try to control from an 4-20mA analog output of OPLC. For example with the V200-18-E2B the load impedance is 500Ω maximum for current output. The input dynamic impedance of the SSR is ≥ 100 Ω but a drop in voltage ≤ 8 VDC @ 20 mA. The application doesn't work from 4-8mA, I suppose the dynamic impedance of the SSR will be higger than 500Ω. I found one solution to use several SSR with an analog output, inserting a Power Suply between the output and the SSR. Do you use it any time? does it secure for the analog output of Unitronics? Look at the image:

@Jenkins thanks for the link @rantonides In the documentation I see in the link the cabling is different than your. look at the page 2: http://www.redlion.net/Support/InfoSheet/G3-Unitronics.pdf

does Red Lion support PCOM protocol? I did not know. Is there info about it in internet?

A smart solution. I usually have an self-resetting timer and load the timer value to MI in a linear FB.

I know it's possible with the Advanced Web Server to download a file from the SD to the PC via web explorer. Now I have a finished application where the customer needs to download the CSV without use the SD Card Explorer. Copy and paste all the application to the .vlp with the embedded webserver is a task for titans but I don't know how to start to make a simple application to download a CSV. It will be about chunks... Anyone can help me? Project: A PLC with IP 192.168.1.201 and a CSV called test. Download from internet explorer: http://192.168.1.201/EXCEL/TEST.CSV

I have a V350 with trends and csv to SD. It works well but sometimes when the customer switch on the PLC we see the SB217=0. If you remove the SD and insert again the error is the same. I have seen that the only way to back to run is remove SD from OPLC, to insert in a PC doing nothing more and back to the OPLC. The application is a datalogger, if we have problems with the SD we will have a serious problem. Any idea to resolve it?

Thanks for your support

I am curious. How do you use the PWM FB to get a ramp?

I don't know if this has been posted, anyway: Now, July of 2012, if you try to download the Unitronics Library from the link in the support page, you can not it: http://ftp.unitronics.com/Downloads/Unitronics_Library.zip I found the ftp folders has been changed and the new link would be: http://ftp.unitronics.com/Downloads-old/Unitronics_Library.zip Fix it! please

We have several projects with Circutor, Carlo-Gavazzi and Entes simple powermeter with modbus serial port. The most of them because their datalogger are expensive. With OPLC the possibility of add digital and analogs inputs improve the application. I think if Unitronics will have a low-costg powermeter like an option we increase the sales about 100-200 units/year. It depends of the final price and the software we can develope. Circutor and Carlo-Gavazzi sell a lot of powermeters because their software of analysis.

I agreed with the supremacy of Windows XP buy anyway is not "Runtime error" a lack of debbuging in the Visilogic software? I said that after to reinstall Visilogic again because of "runtime error 91"

Apple world and android too. Everyday someone ask for monitoring their industrial machine from the smartphone. But there are two problems around this: 1.- how to connect to the PLC and 2.- what is about security? I think the solution will be web-service, it's a simple way to access to the machine. But it will be necessary learn to works with VPNs, DNS, HTTP. At this moment we are solving this kind of applcation with eWON, a modem-router "something-more" communicating with the OPLC Unitronics but it's a bit expensive for a lot o simple applications. I hope the next generation of OPLC Unitronics will able to add more control to GPRS, 3G connections, in cibersecurity and easy of use.

Windows 7 64 bits, it was working properly up to the PC switch off of a sudden. I reinstalled Visilogic erasing folders and now it work again. Is there any file we can edit to avoid Visilogic try to recover the failed application?
