Hi, In accordance to specification of IO-D16A3-TO16, max. PWM frequency is 32K. MI is fitting this. You stop PWM by writting 0 frequency. *You should use slowest servo when connect to IO module. B.R.

Hi Gabriel, I save csv file each 0.1 sec and at the same time transferred to web folder large file during 25 minutes. No errors happens. If you wish our help - send your project to support@unitronics.com and we will do our best to simulate and correct problem. It will be useful to know content of SD card web folder and list of updated files. Ideal will be to have your project, SD card image and zipped files you used for update. This will allow to simulate wery similar to you configuration. B.R.

Hi Gabriel, Are web pages accessed when you update files? What communication protocol you use? Send your project to support@unitronics.com and we will do our best to simulate and correct problem. B.R.

Create Data Table and trace sending email results. do retry for one email for statistics. Save failure code. You can open DOS window at your PC/Laptop and connect to e-mail server by Telnet "telnet xxx.xxx.xxx.xxx 25" (You can find at Internet how to do this). Check server replay and send short e-mail. Look for replay. This will tell you if PC to E-mail Server communication works or not. Do the same test with other email provider. For me it seems E-mail provider problem. You can create Data Table, where you fix e-mail send result and error codes. Retry sending email to other e-mail server at the time when error happens. Ask in forums if anybody have the same problem to send e-mails with the same e-mail server. B.R.

You have to check if SMS in SIM memory are valid (defined in SMS Configuration). Not valid SMS stay in SIM memory and fill it. In this case you have to schedule SMS memory clean. See Help description for SB 193 and SI 187.

Did you realized previous recommendations?

Hi Gabriel, You have to review your project to find if you use proper protection normal closed contacts (SBs), and if all SD Card operations are run by -|P|- or -|N|- contacts, and use one-shot conditions. Unproper protection, or not use it at all, will lead to such corruption. Other thing is 3rd party programs at PC/Laptop, that used for defragmentation etc. These programs left at any connected media hidden files and directories with long names, and these files/directories are not compatible with OPLC SD Card file system. If you are in doubt about these things - send you project to support@unitronics.com for review, and we will help you to improve your project. If you have corrupted file system at SD Card, you should make full format twice - with checked and unchecked Windows Format option in SD tools, before you use it again. B.R.

Hi, You have to swap these 2 16 bit numbers in your SCADA. Then it will be right Float representation. B.R.

Dear Adriano, Sorry, but it is completely not allowed to make an “extender” between Jazz port connector and Jazz add-on modules. The signals on the Jazz port are low voltage and sensitive signals and all the add-on modules are isolated. Which Jazz model you’re using? How many machines like this you have? If your Jazz will have built in USB port, will this fix the problem?

Hi Gabriel, Thank you for pointing us to this. Unfortunately this message appears even if there is an even number of Bytes in string. But it should indicate odd number of Bytes. This will be corrected in next release of VisiLogic. You should keep number of bytes in string to be even (2,4,6,8, etc. Bytes). Then it will be no problem.

Hi, Please check what is a maximum load impedance for Scale transmitter. AI4-AO2 have internal impedance 121.5 ohm. For 130-TA24 it is 37 ohm. It seems that problem is here. You can test transmitter with Digital Multimeter and different resistors. Lets say it works with 100 ohm resistor. Than voltage will be 400-2000 mV. If 1600 mV range can fit your needs - you can use 0-10V input and linearize it. If not - you have to look for other transmitter. Or use Current Loop Repeater, if you can find one fitting used Scale transmitter.

Hi, It seems trhat you can have much more problems with one universal program than with number of separate versions. It will be good to know your configurations, model of OPLC, periferal modules, snap-ins etc. Then advice will be more specific. BR

You have to use TCP Slave port configuration for OPLC, and TCP Call from VisiLogic.

3 models of WaveCom modems are supported: WaveCom 1206B, WaveCom 1306B, WaveCom Fastrack Supreme. For other models you have to choice "Other..." and provide initialization commands. "Other..." will work in SMS mode. GPRS/GSM in this case is not supported. Or you can use FB Protocol to realize used modem commands. In this case you have to manage all statuses etc. (State Maschine).

Hi, 0.1C difference between 2 OPLCs is not a problem. From Datasheet: Resolution is 0.1 C. Cold junction compensation error ±1.5°C maximum. Full-scale error ±0.4% Linearity error ±0.04% Warm-up time ½ hour typically, ±1°C repeatability Everything is in range. So why do you panic and require schematics? It seems useless. Isn't it? My advice is to use it as-is. I see no problem in your configuration. BR

Hi Anton, You cannot reset and/or acknowledge alarms by any bit assignment. You have to do this from Alarms Display of OPLC only, this is by design and intended to track, that alarms being reviewed, acknowledged and reset by phisical persone, who is responcible to take action. As regular, acknowledge/reset of alarms are accessible with password. Assigned bits for acknowledge and/or reset is informative, and change status when assigned action done. If you wish to reset remotely alarms - it seems, you do not need embedded alarms, and you have to use your algorithm, which you have to develop. B.R. *I cannot tell you nothing about F2 until I will see your project.

Hello Delphin, Your question is "How to display realtime Trends, include history, on modile phone". Please open a new topic for it in "Vision PLC series and VisiLogic", like Flex727 did for "Trends" function. It will make an order in topics and will simplify search for members. In topic body please provide information about mobile phone you wish to use, screen resolution etc. This will help to answer your question. BR.

Hi, About *.UTR and other files on SD: These files are compressed, especially information about headers, to make this information as compact as possible. Unitronics does provide set of utilites to convert such files to Excel format for further graphing. Unitronics does not develop mobile applications, but such applications may be developed by 3rd party. Keep looking "http://www.unitronic...ird-party_Utils" at Unitronics Support site, or google for required topics. BR.

Hi, Long variable will be entered as 2 variables only. Open example named "Long integer-one line PLC_all possible functions.U90", change Hardware Configuration to Jazz and run it. See how it works. Long numbers are not native for Jazz, so there are some strict rules to follow. You have to show Right number with leading zeroes.

You can use next algorithm: Use SI 4 and DIV function. Divide 0x1234 for 0x10 (16 decimal). You have last digit 4 (decimal or hex is the same) in SI 4, and result 0x123 in other MI. 4 is a last digit of decimal time. Add it to an empty result. Divide 0x123 for 16. Multiply SI 4 for 10 and add to result MI. Continue more times to finish. You have decimal result for next use. For conversion from decimal to hex use similar algorithm. Is this what you need? B.R.

Hi Olaf, Validity.txt show you what file had a problem during e-mail transmit. Check if you file not updated when you send it. Check resulting code. Check if a file name for email is valid and located in the folder you mentioned. B.R.

Hi, At this time VisiDiff does not support Enhanced Vision models. V570 is an Enhanced model. We are sorry for inconvenience. BR.

Ag Automation, Please open a new topic. This will help to organize Q&As. Thanks.

Hi Russ, Send your project to support@unitronics.com. It will be better to see it and advice you solution. BR.

Uncheck "Start with clear field" and test again.
