  1. So, the answer is no then? I noticed that if I do "Show structed text" in ladder I get a _op_op version of the tag. If I use this code, for example System: "RTC time.Seconds" in the C function I can call and use it and it appears to work. Am I breaking things by calling this code in C function?

  2. Well I figured it out. If you access the plc with VNC via remote... You can hold the screen in the top right corner just like you are standing in front of it. After there you can go to plc properties and reset password to default

  3. hi Vesp123 what I meant is that the unistream share a system variable called "General.Milliseconds Counter" that is an UINT32 variable that start to count the milliseconds from the PLC power ON. so you can save, when you want, its value to check how much time is gone...like a timer...obviously, or better I think that is obviously, this procedure need a "finite state machine" logic...so some other variable/s in your struct will define which steps are you performing for each single struct...attached an example about what i meant.

  4. You build your UDFB to contain all your room arguments Then you pass it which room/device you want it to handle and trigger the UDFB with rising P in your global or main program. Using a conditional statement like equal, only the desired sections of the UDFB runs. In the picture "LoadActuator" is my UDFB and the top 2 rungs are inside the UDFB. The bottom is a call showing how I pass it A) SelectedPostion (pointName)and B)Actuator Number. -Swervo

  6. Hello everyone! I have 30 pcs of sm35-j-ra22 plc and they are all connected to ethernet line. I want to view and control the data I get from these on the USP-156-B10 HMI Panel. How can I do that? I think i have to use "Scanner Adapter" and define all of SM35 PLC's ip.

  8. SM35 series PLCs does not support Ethernet/IP. You have to use MODBUS TCP. *Only UniStream series PLCs supporting Ethernet/IP.

  9. I moved this thread to the correct forum. For coils, the DECIMAL address should be the same as the MB number, with the proviso that Unitronics addressing starts at zero whereas the MODBUS standard (and Siemens iirc) starts addressing at one. Therefore when addressing from the Siemens Master, add 1 to the MB number to get the correct decimal addressing for the master.

  10. A woman is visiting her husband who is in prison. As she is leaving, she tells the prison guard; "You need to stop working my husband so hard, he is exhausted" The prison guard laughed and said; "Ha, your husband does nothing but eat, sleep and stay in his cell" The wife says; "Well that's odd, he tells me he's been digging a tunnel for months...."

  11. Rikki, please send your request direct to support@unitronics.com This forum is mostly users who are volunteers solving other's issues. "Support" is the people who make the units and they can easily provide the older version. You may have a delay in response, due to them being in Israel and the social customs in place there on certain days of the week. cheers, Aus

  12. dears, i think that I understood the "probem"...at the end I was adding some String items , also the ";" separator and the "EOF" simbol", bu tthis last has to be added directly in the buffer as "costant" and not as String. Now seems works...I have to try to read from SD file into the buffer...

  14. Hello Ricardo, A good and safe way to have internet remote access via Webserver or VNC is to use a VPN router with integrated cloud service. There are various options available such as Ewon, Tosibox and MBconnectLine products.
