  1. Choosing the right OMRON PLC - Vacuum System

    Hi All, I'm hoping someone can help me. We're currently in the very early stages of re-designing how our vacuum system works. Currently we have 6 vacuum pumps supplying around 8 different packaging machines which we currently have to turn on and off manually depending on the demand on the machines. The challenge is to design and implement a part or fully automated system to control the current vacuum pumps - The key requirements are Supply must equal demand for the vacuum pumps - so they are only used when neededAutomatic switch-off when not in useCycling the use of the vacuum pumps so as not to overuse oneAbility to take a pump out of the loop for service/breakdownsManual override/shut-offScope for expansionUser-friendly interface (possibly touch-screen/wireless)I am a complete novice when it comes to OMRON PLC work and would like some guidance on possibly similar projects or at least pointing in the right direction with which PLC to go for. Thanks for your time Jack
  2. PCS7 with S7-410 for Dummies

    I just need to understand a little bit more about the PCS7 architecture, if someone could point me to a document or a video or something, or just give me a few sentences to break it down it would be greatly appreciated. The reason being, we have a quote that we are working on for a customer over seas and are being told to quote our equipment with an S7-410 PLC.  I am very unfamiliar with Siemens in general, but completely unfamiliar with the PCS7. Our equipment is typically if not almost always stand alone equipment that communicates discretely to the rest of the facility.  Our equipment is not part of a process line, but rather feeds the process line equipment what it needs to perform its operation. I have been led to believe that the S7-410 PLC must be part of a DCS, so it does not seem like the correct fit for our equipment.  I just want to confirm this and learn a little bit more so I can explain to our sales folks and ultimately the end user why it is the wrong option for us and our type of equipment.   Thank you!!!

  3. Hello everybody, I'm new to Beckhoff and I couldn't find the solution yet, I hope someone can enlight me. I need to integrate two distinct and already functional systems: one is working with a Raspberry connected to other devices; the other one is a Bechoff unit getting sensors data. Now I need to get these data captured by the Beckhoff and send them to the Raspberry. Does someone know if I can access these sensors data in a Beckhoffs unit (it's a CX9020, but we can use a EK1100 as well...) by the Raspberry without using any other intermediate device (just the board and the unit)? Thank you!

  5. Hiya Guys, New here (first post!) - and I'm fairly new to Connected Components Workbench, so apologies for the mammoth post! I am currently developing a System using one Micro850 PLC and one PanelView C600 HMI. I am able to update the current HMI time by sending Unsigned-Integers to Global Connection Tags: System Clock – Hour ($SysClockHour);System Clock – Minute ($SysClockMinute);System Clock – Second ($SysClockSecond);However, if using the same “update time” more than once, this method does not work as the HMI is looking for a “change” in a Tag before an update occurs (Tag-specific). For example, we require to be able to receive a “synchronisation signal” on a digital-input on the PLC each day at 15:00:00. This will only work once as, even though the HMI’s current time updates every second, I will still be sending the values “15”, “0”, and “0” to the above Tags (which will therefore not force an update – as they haven’t changed). I cannot reset these Tags without updating the current Time – as any number “out of range” causes an error (incidentally the errors are shown on the HMI to occur on Tags “SysClockSecondTimed”, “SysClockMinuteTimed”, and “SysClockHour” – note the omission of the word “Timed” on the Hours error…). There appears to be no reference to these “Timed” Tags anywhere in CCW, and I have no idea why the “Hour” update errors on a different (the correct?!) Tag. It’s a pretty confusing problem and difficult to explain… it took me a while to get my head around it – and I can see what the code is doing! J I've looked for documentation on how these Global Connection Tags work, but I can't find anything. Everything I (think I) know so far is from extensive testing... so if anyone knows of any documentation, or has any suggestions as to how I can achieve the required result - that would be massively helpful! Thanks for taking the time to read all this! Cheers, Steve.
  6. PLC Integration by SCADA

    Hello Experts, Good day to you all. I just can’t figure how I will integrate five S7-300 PLC. CPU 315-2dp. (1.Blow moulding-> 2. filler-> 3. labeller-> 4. packer-> 5. Palletizer) I just want to get the speed of its machine, the output rate and the alarm, this is purely monitoring, archiving, no need to control anything here. I planning about SCADA system. I’m thinking if I could do the same way in my previous project, which I’ve done in profibus master/slave for two s7-300. But this time the five PLC’s already set the profibus as master to the danfoss drive, sew drives, ET200s and many more profibus slave. I plan to buy 1 PLC as master and I will set all as slave, but how since all the five existing PLC, its profibus already configured as master. Thank you very much. All your inputs is really appreciated.
  7. Hello all, I am experiencing an unusual (and what appears to be an unheard of) behavior in my CompactLogix L18ER controller. I am setting the date/time of the controller from my work station, however when I GSV WallClockTime, it is reporting 4 hours different. I have asked our local resources as well as done some forum and knowledgebase searching without result. Has anyone encountered this before? Attached is a screenshot of the controller time vs. the wall clock time. This isn't mission critical since it can be manually adjusted however I would like to understand what is taking place that would cause this behavior. Thanks!
  8. Need Logic

    Hi everyone, I want to develop a logic for security alert system. I have to generate an alarm at irregular time intervals. No one should know the time interval. PLC has to give a digital output at any time. How to create this logic? Regards Joshua
  9. Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi
  10. NT21 System Program

    I currently have a NT21HMI that does not have the system software loaded. I do not have any system programs with the *.21 extension. Where can I find the NT21 system software?
