  1. Hi! I have in my system a SM43-J-R20 PLC and A Frequency Inverter from Vacuum (Schmersal). I jus want to show the frequency of the motor on HMI. Think in using I6 as analog in, i did the JP8 and JP9 both to B (current) The thing is, I don't kwon how to wire it. See the manuals below. PLC/HMI Frequency Inverter Manual Terminal 18 (Analog Out) Terminal 5 (GND) Terminal 13 (Digital Out Comum) Anyone can help me? Thanks!
  2. Hello, I'm trying to comand an output with a button, but when I'm on online mode, the direct contact I use in the transition refer to the output don't work. I don't understand because it's a simple action. Bits are high but transitions don't go forward. Furthermore, there are some coils which stay activated without reasons. Thanks for your help
  3. Dear Community, I couldn't find anything in the UniLogic help files about array functions. Is it just me or is the help section grossly incomplete in UniLogic ?! Visilogic seems to be very comprehensive in help topics with examples for every FB in the software. Feel some uncertainty without help topics on select functions, especially with the differences in terminology from Visilogic. Example being: a vector copy of 30 MI's in Visilogic is equivocal to "copy array part to array"?? Failed to find help topic with example. I tried to build a UDFB last night to function like Visilogic's vector linearization function and gave up. Just stacked individual linearization functions instead. I get the feeling the authors of UniLogic were not the same people who composed Visilogic. Old dog learning new tricks, I'll get there.
  4. Unilogic help files

    Any idea if/when the Unilogic help database will be updated to include text/diagrams of every unilogic function? The array's section has functions that I can NOT find specific descriptions/examples in the help files. Maybe I am missing it. I learned PLC programming on AB MicroLogix and started using Visilogic with ease. Talk about hitting the ground running (sprinting even). My first project in unilogic is proving to be very challenging. There are several features I realize are superior in Unilogic and appreciate! However I am finding several functions that were present in Visilogic that are NOT in Unilogic. I understand progress and advancement have a precedence to keep a competitive edge in the market. In my humble opinion when you roll out something new it's nice to have all the function and utility of it's predecessors (Visilogic). I miss the MODBUS R/W mixed data; while not a standard defined MODBUS function it greatly simplifies data exchange in a system that is built exclusively with Vision PLC's. No more drum sequencer. No more Function in Progress bit. Granted these functions can be logically constructed in Unilogic, I don't see how this saves me time in project development. Guess this is the feedback you get from an old school guy who is a PLC programmer and NOT a computer (C language) programmer. P.S. Some kind of field descriptor on the function blocks where tag entries go would be awesome. A,B,C,D,etc... Don't mean much to me. Ezample: the linearize block, had to go to the help to see what goes where. In leiu of A,B,C,D fixed descriptirs like IN, X1, X2, Y1, Y2, OUT would be nice. All blocks have the alpha field desrciptors and they can mean many different things. I guess as it stands until you get on top of the learning curve unilogic is not quite the time saver it is once you have intensively read and memrorized the (incomplete) help files.
  5. Hello, I'm just wondering what is the best way to log some informations. I will need following: Login/logout, battery low - switched to charging mode and so on. I will need to have separate display and the log should have time and thing that happened. It will probably have to be in table because it suppose to have "history" feature, like you can list back in time and see what happened. I've been searching for answers in help feature, but i still don't know how exactly do it. Any advices are greatly welcome! Sorry for my bad english. Best regards, Martin P.
  6. Hi I am a newbie to Visilogic and I am really sturggling to reset me TD timers to the preset value after they have counted down (in this case 15 seconds). I have attached a screen shot of the visilogic screen of my current configuration of the timer. Please can someone help and tell me what I am doing wrong as I am pulling my hair out! Thanks Russ
