  1. Hi there,  I'm downscaling my business in Western Canada and have some legit software licenses I'm going to sell. This was my first thought as to where I might explore selling/transferring licenses, but I'm also open to polite suggestions.  I have: one Studio 5000 Full Edition ESD Software (9324-RLD600ENE) (software & valid license) two Siemens TIA portal software packages & licenses with Step7 v14sp1 and WinCC Comfort Advanced V14sp1 (software & USB dongles) an unused Simatic WinCC SmartServer license (software & USB dongle) one Progea Movicon 11 Scada/HMI developer license (software & USB dongle) one Progea Movicon NExT DEV3-FL (developer license) (software & USB dongle) an unused Progea Movicon NExT Scada license (RTCS3-F-1K+WB3-1K) for site install (software & USB *unused) one package of Schneider Movicon with license (Vijeo Designer, Unity Pro S, and SoMachine) (software & USB keys) Thanks! Mark
  2. Hi, very new to PLC programming and desperately looking for some help to finish my project! I need to program a pump to run based on the level in a holding tank. The start/stop set points change throughout the day based on the time. For example, function for the start set point is 1.15372×10^-6 x^6 - 0.000114068 x^5 + 0.00448866 x^4 - 0.0883477 x^3 + 0.877893 x^2 - 3.57417 x + 7.5, where x is in hours. How can I access the PLC time (current hour and minute) so I can use them to calculate the set points? Does Unity Pro XL have pre-defined variables for these?
  3. Qucik question guys, im a noob on Unity Pro and was wondering if uploading a project off of a plc already running a program will affect the operation of the already program?
  4. Hi All Been trying to change the column width of an LD Section (is this possible?) Currently there are 11 columns - I would like a few more if possible In Tools -> Project Settings -> Program -> LD there is an option 'Number of Columns' - whatever I try and change it to it sticks at 11 At the same location there is a setting for 'Cell Width' - Single, Double, Triple which works fine Circles again..... Regards
  5. Hi,  I've design a program on Unity Pro XL v13. Unfortunately, now i have to open this on Unity Pro XL Version 11.  Is there any way to transfer my project from V13 to V11. There is some compatibility issue.  Need Help. 
  6. Hi   First post in this forum - hope I'm not duplicating topics..... I've had prior experience with Siemens S7 Tags for I/O allocation - how is it done for the M340/Unity setup please ie how do you assign a physical address (say %I.0.1.5) to an input in the program? I imagine it is somewhere in the 'Configuration' section where I have defined all the modules?? I find the standard help quite hard to follow and find what I'm looking for - anyone have any better documentation. Also I am feeding a quadrature encoder output into a high speed counter module - any tips/examples of suitable program structure to use? Thanks for listening.... Andy  
  7. I have one value which i need ti give as an input. But after every 10-20 secs value changes from "+ve to -ve" so what I need to do is If the value is "+ve" It should pass as it is and if it is "-ve" value should change into Positive . what logis chould i do as the values is from Array.
  8. Dear colleagues, I need to reset values in a range of registers (for example from %MW100 to %MW599) in the Unity Pro. How can I do it with one command? Regards, Waldemar  
  9. PID regulation PT

    Hello   Does someone have a good way to control pressure using PID in cx-programmer? I got two pumps and one PT(4-20mA) Half the year only one pump need`s to run (about 3bar)  but in the season (i work in a fabric) two pumps need to be running (about 4bar needed) except in the night. I`m going to use HMI for adjusting the setpoint so there is no need for any clock/date for this to change itself. The question is how to get one of the pumps to shut down when the need for pressure is not so high. And get the pumps to change "main" pump sometimes so one pump is not running all the time.   Hope this was understandable    
  10. Morning Guys, For my latest project I need to read a gas sensor via 485 from a Momentum PLC. I've been through the help files, but they seem to only raise more questions than they answer, they only seem to reference PLC -> PLC comms. I've had a play with the 'MBP_MSTR' & 'OUT_IN_MBUS' function blocks, but i can't seem to get anywhere, Has anyone got any examples of reading in data via 485, or can anyone lead me in the right direction?
  11. Hi,  i want to read real time and date in simulation mode. How can i do this in Unity pro? Thanks for helping
  12.   Hi All.I hope you are all doing excellent and also, hope you can help me.Today I contact you as I am having some issue when programming a PLC.I need to create a piece of software that:1) Can control a random number of machines at any given time.2) Each machine is a slave 3) They are exactly the same, do exactly the same thing.--------------So far I have managed to create a piece of code that allows me to control a fixed number of machines but things get complicated when one job does not need 10 machines but 20 and the next one needs 15, and the next need 5 and so on.I have thought to use arrays to do this job but this is an area I have not touched at all and I would like to ask for your advice in this area.I hope everything is understood.Thank you very much for your help in advance.
  13. Hi guys, I'm attempting to implement a fuzzy logic controller from scratch. I plan on using a lookup table to assist with retrieving the membership value. Does anyone know how to implement a lookup table. I know there is a L9P_LKUP block in the LL984 editor..except I'm not sure how to actually enter in the parameters or read from it.   Kind regards, Luchek
  14. Hi all Does anyone know how or the Tool to use for Exporting Variables from Unity Pro so I can remove the Register base Addressing for Various Tags and insert Direct Addressing I/O to the Alias Of Attribute for those Variables? This then to be Imported back into the project with the New Aliasing in affect. I have spoken to Tech Support and they say there is a tool (Excel Add On) that comes with V11 in a directory called Extras. I cant find the directory lol. He is coming back to me about the tool but could not tell me if this tool will help with the Aliasing I need to do. Thanks in advance for any help or ideas on this.
  15. Gentleman…   Does Rockwell have any simulation PLC code that mimics an SMC-Flex soft starter?  Since we are using those (as well as the E3+ and E300) I would like to develop a model environment for starting of several drives.  In a specific case, we may have 3 or 4 drives in a pool of drives in which only a subset must be running at any one time.  Development of ladder logic for starting and maintaining those drives running while considering various fault conditions and startup issues would be very helpful in our environment.  I would like to be consistent among various areas within our plant that we incorporate pools of drives, from 4 to 2.  Having the ability to test in the lab would be very beneficial.  Thank you, David
  16. Greetings, We (in the steel industry) have many pumps / motors (large and small).  Generally we use soft-starts,  cross-line starters (E3+) or even Flex drives. There may be several motors in a pool to start where we need only say 2 of 3 to be running at any one time  When it's time to start them, we may need to stagger start them, if one fails, the spare may need to start.  My question to the group is... Are there any philosophies out there (and hopefully pseudo or actual code) as to how to start a subset of motors/pumps within a pool of motors and maintain the configuration running ? I appreciate any and all comments. David 
  17. Am I right in thinking that you can't pass arguments into a subroutine (SR Section) in Unity Pro? I am using v8 and can't seem to find a way of doing it. I want a reusable function that I can just call on demand, so a subroutine is perfect. But I need to call it with different parameters. Will have to be a DFB is this isn't possible, I guess.
  18. Hi Everybody. Where can I download a trial copy of Schneider Unity Pro 8.0 from? I have looked everywhere but couldn't find anything at all. Much appreciated.
  19. Dear All. I need an Instructor to teach me Unity Pro XL Programming used in M340. I am willing to pay whatever you ask for it. It can also be off line by Emails or whatever your Schedule works best. I need a coach trough out my Start and competition of the project. Thanks in advance.
  20. Hello all, first post here, and thanks in advance for the help. I'm a fairly green SCADA and controls designer and although I worked fairly extensively with these systems in the past, I followed a sightly different career path for the last several years and haven't had my hands on a PLC that whole time. Started a new job and am rebuilding my knowledge with it. Fortunately my company afforded me a PLC to take home and mess around with for this purpose. I feel pretty dumb as I am struggling to even connect with it, haha. Here are the stats: Backplane: TSXRKY4EX (end caps are securely in place) Power supply: TSX PSY2600 Processor: TSX P57 6634 First I attempted to connect via ethernet, using the IP address sticky-noted to the front of the processor: 10.1.1.80. No luck, "PLC address is incorrect, or PLC is busy, yadda yadda". As I understand, the default IP address can be converted from the MAC address. The last two MAC address numbers were: CF.87, which gave me the address 85.16.207.135. Same result with this. I tried pinging both address from the command console and had no luck there either. I happened to have a USB to unitelway adapter (Telemecanique brand) and attempted using that as well, Address:SYS.. Media:Unitelway. No luck, same answer. After a lot of frustration and hours spent scouring the internet for answers, I took the nuclear option and pulled the battery (while unplugged) and replaced after 30 or so seconds. I was assuming this would clear the memory and reset the IP to default (85.16.207.135), afterwhich I could reconfigure and start fresh. Unity still can't connect nor can I ping it. It should be noted that I am using Unity Pro XL Version 8.0, on a VMware image. I did attempt pinging from both the VM and the host machine, both can ping other known devices so connection by the VM through the host shouldn't be the problem. Neither the VM or the host recieved a ping reply from the PLC. Any help would be GREATLY appreciated. I feel I have exhausted all options and I hope I didn't shoot myself in the foot by pulling the battery. As far as whatever program was on it before is irrelevant, the PLC was given to me to do with whatever I wish, so memory loss wasn't a danger. I just need to connect to it. Thanks!!
  21. Any one have a simple Lead /lag pump FBD in Unity? just want to take a looke at the process. Thanks in Advanced
  22. Hello i need to write a very long net in unity pro, the maximum length is 11, can I continue the net in the net below net using a conditional jump to a label?
