  1. Hello guys, I am new to this forum and have some problems with my PowerFlex755 EENET frequency inverter. I want to do a point to point positioning task but my problem before I can have a look at the point to point positioning is, that the inverter is always running with 5Hz as soon as I give the start command. Even if I write 0.0 to the reference the output frequency is about 5 Hz. When I change my reference speed to 10.0Hz the output frequency is 12.X (see attached screenshots). . I thought that maybe a min frequency of 5Hz was set somehow, but I couldn't find a parameter and that wouldn't explain why I have 12.X Hz as the output frequency with a setpoint of 10Hz. And an other question, have someone experience with positining tasks with a PowerFlex755 and Point to Point positioning? I think in the first step it is not working because of the problem I described above, but maybe someone have a programming example or could tell me where I can find some information about how to use the Point to Point positioning?   Thank you for advice!  Matthis Josewski
  2. Dear automation friends,   I just like to put some issue in the clear that I have seen no reported issues on yet, but it is killing me. Maybe some other people in the world also have this issue. We use Windows 2016 on FT View v10. All patched with all compatible patches (both Windows and Rockwell). We install this software a lot but we only got this issue seen/reported on windows 2016. I never had a Rockwell issue that took so long without getting it fixed. Support is also not really helping.   We just have a setup of Windows 2016 with 2x redundant FT View Servers and about 10x Clients with each 4x screens. The HMI clients run perfectly but every few days, 1 application (on 1 of the 4 screens) just crashes "DisplayClient.exe application crash...". That closes the HMI interface and then the users needs to click on the hmi.cli file to launch that screen again. Refering to ntdll.dll in the windows events. No additional info except for the windows error reporting that is unable to contact the internet to send the crash report. Looking in the FT Diagnostics, it happens while the operator is operating the hmi screen. Not when there is no activity.   We reinstalled 1 client completely from scratch, including the OS, domain integration, everything brandnew. And 10 hours later: crash on 1 of the 4x screens. In a control room with almost 30 screens, this is very annoying and unacceptable.   If you have a similar issue or got the issue fixed, please let me know. If you have a similar issue and don't have it fixed, we can share more detailed logs.   Best Regards,
  3. Dear Team,   We are looking for a suggestion to drive a motor which is away about 2100 Meter from its starter. The Pump is located in a pond in the forest which is 2000 Meters away from the nearest building. The pump capacity is 55kW and we are considering 55kW HD VFD as a starter. As we see the distance is much higher we are looking for you valuable suggestion about how this thing is gonna work without any abnormalities.
  4. I put together a demo of the c# library I am working on for Rockwell PLC. It basically allows you to parse/construct the L5X files for code generation, documentation, and other uses.
  5. Hello, I'm currently researching Rockwell controllers for our PLC implementation, but there are some aspects I couldn't find in the manuals.  I would greatly appreciate it if you could provide more details on the following: ①Procedure for Adding Modules Online: In the manual "1756-um001p-en-p," it mentions the possibility of adding units online.  However, I couldn't find specific instructions on how to do this.  For instance, with I/O modules, I assume it's as simple as physically attaching them to the chassis using RIUP,  but I'm unsure about the software side (e.g., Logix5000) and any operations required on the controller itself. ②Online Module Addition for Remote I/O: The manual mentions that EtherNet/IP modules can be added online. Would it be possible in either of the following scenarios?  ②-1 Adding I/O modules to the chassis of an existing remote I/O station.  ②-2 Creating a new remote station. Our investigation has hit a roadblock, and we're in quite a quandary.  If you have any information on these matters, your guidance would be greatly appreciated. Thank you.
  6. Hey everyone, I'm new to programming PLCs and I've run into a problem. I have a Micrologix 1400 Series B PLC, and for the past month, I've been using a free trial of RSLogix 500 Starter. But now, the trial ran out, and so I bought a license for "RSLogix Micro Starter". The problem is that when I downloaded my updated file to the PLC for the first time with micro starter, the PLC's outputs don't work anymore. I checked the PLC screen and the inputs from the HMI screen are getting recognized, but the inputs from the physical sensors are not. Also, none of the outputs are being activated on the PLC at all, which I can tell by looking at the I/O status on the PLC screen itself. I then uploaded a new test program, where you press a button and a light turns on, but that doesn't work either. I haven't changed any of the physical wiring, only thing I've changed is that I'm using RSLogix Micro Starter as opposed to RSLogix 500 Starter. I spoke to a Rockwell technician about this and he said that there shouldn't be any problem, as I haven't done anything wrong. So I now ask everyone on this forum if they could help me out a bit.
  7. Hello, has anyone had success in creating a wedge with borders that change due to its assigned tags? Attempting to create a range on a gauge using wedge, but am unsure how to approach this considering it wouldn't be rotating the wedge around a point but rather changing the size of the wedge. 
  8. Hi there! This is my first time using Rockwell automation software and I have some questions I can't answer. When I'm running the FactoryTalk runtime application with a simulated controller, I get disconnected from Logix Designer, so I can't online watch the program. If I try to simulate using 'Test Application' in FactoryTalk View Studio, it appears to communicate, but buttons don't make any effect when pressed.   Hope you can throw some light on it! Thanks in advance!  
  9. Hi gentlemen, I have I bottle capping machine and I'm reading the torque value from one of the Sureservo2 drives. As the bottles pass through the machine, I need to display the peak torque value and hold it until the next bottle passes through. This machine could run up to 100 bottles a minute. I would also like to display a 10 bottle peak torque average. Does anyone know of a good way to do this? Any help would be appreciated.  
  10. Hi there! I have an Allen-Bradley SCL05/04 PLC. It has an RS-232 port, a 3 DH+ connector and a circular port with programming pins. An NB-Omron HMI is connected to the RS-232 port. And of course I can only have the screen connected. Is there any possibility to connect through the PLC programming port to be able to follow the program online?   Here is atached photos of the PLC:      
  11.   Replacing dead powerflex 700 with 753 talking via ethernet. Any good instructions on how to update the file from 700 to 753 on rslogix 5000?                                    
  12. Hi, Does anybody know if its possible to access the "Inhibit Module" tick box within the Hardware Device Connection tab from the PLC code? I'm hoping to turn this on / off depending on whether certain modules of machine are physically installed.  e.g. A Kinetix Drive / Point IO etc. Thanks
  13.  We have been tasked with saving money on equipment within our 4 plants here in the USA. I would like to investigate using low cost HMI's, I've had great success using C-more in the past. Has anyone had any of the several low cost HMI's attached to Emerson PAC (AKA GE Prophecy) PLC's? has there been any connectivity issues? I'd like to try one to replace the Emerson HMI's which are hard to source, and expensive. I believe any time setting up a low cost option would offset the cost of the Emerson, and open up our choices of HMI's and not be boxed in to one brand. We also use Profinet along with Ethernet connection, I believe the Emerson HMI only uses Ethernet (for us) but if there is a Profinet version that is easy to set up, that would make it an easy sale for me.   This HMI would also have to work with the older 90-30 series PLC's, but i'm pretty sure the communications have not changed much from the to the stand alone RSTi-EP and RX3i PLC's. Any advice would be appreciated.  Have a great week. 
  14.  I've been debating whether to stay at my current employer who uses Emerson PAC software, vs going back to a similar company that uses Rockwell (compact/control logix) mainly because A-B is used by most companies around here. I work as a technical temp, usually 12 month contract jobs. Learning the Emerson PAC (aka Prophecy) seems to be a waste of time, since I am not aware of any companies that use it, other than my current employer. My placement company is pushing back, but I know I am correct. I do not have hard numbers, but I've been around the industry for 20+ yers, and have only seen 1 company use Emerson.   Does any one agree or disagree, or have some circumstantial evidence of the actual market share of A-B vs Emerson. I am mainly working in the Auto industry, in Michigan. Just looking at this site, there are 3200 postings for GE and Emerson combined, vs 58,000 postings for A-B. 
  15. Hello all,   I am working on a batch computer for a concrete mixer, and the computer that was running the plant before has stopped functioning. It was an old PC running MS DOS. The code is encrypted and replacing it is not a cost effective option.   I therefore am looking into using a PLC to control this batch plant. I have a setup that was in progress by another employee who no longer works for us, it is a CLICK PLC from Automation Direct, and it is supposed to be paired with a EA9 T8CL touch screen HMI from the same company. I would like some advice on just some basics, I would greatly appreciate some input.   I essentially only have one input, and that is an analog scale, 0-20mA input. I have digital outputs for sand, gravel, cement powder, and a water meter for adding water to the mixture. I have one final output, an additive for reducing the required water in the concrete.   What I would like to create is a program that when it is told to start, looks at the scale, and if the scale is less than say 100 pounds, opens sand until it hits 1700 pounds (as an example), then turns it off. Then it turns on the gravel and adds that for another 1700 (again for example, all these are variable), turning the gravel off after. Next the cement, and so on. I don’t need someone to write the program for me, but can someone point me in the right direction on using an analog input to turn digital outputs on and off? Again, your help would be greatly appreciated.   Thanks for taking the time to read this long post.
  16. Hello, everyone! I am following this YouTube tutorial where it teaches you how to add a block of Modbus server within Studio 5000 for communication with plc ControlLogix. The video: However, according to a comment from the author of the video himself in my comment I can make such a connection through a Modbus device. How do I do this within ur5 and how can i access UR5 inside Studio 5000?
  17. I have a 1747-L30B SLC Brick and it is set to load from EEPROM on boot S:5/8, Error S:1/10, and Run S:1/12. I need to make changes to the program and then store it to EEPROM via "Comms>EEPROM>Store to EEPROM."  When I attempt to store the program with changes, it displays the message "Insufficient Memory Module Size." I assumed the EEPROM memory was maxed out, but I also uploaded the existing program currently stored to EEPROM, made no changes, and attempted storing it back to EEPROM and received the same message. Any advice?
  18. I have a PLC ladder logic problem that I am stuck with and would like to know if there is a solution for it. PLC Ladder Logic Problem on PLC Fiddle: Automatic Window Blind There is a window blind that is controlled by using an opening and closing motor. There are 2 IR sensors that act as limit sensors to identify the boundaries of the opening and closing of the blind. The blind can either fully open or fully close. The blind is fully opened during day time and is fully closed during night time. We assume that the day time is for 12 hours and night time is for the other 12 hours. The PLC ladder logic must include at least a SENSOR, an ACTUATOR, a TIMER, and a COUNTER. You may use PLC Fiddle to draw the ladder logic: The process is as follows: 1. Assuming that the blind is now fully closed (during night), the night time 12-hour count down starts. The counter is done using a timer that counts 1 second, and after every second, the counter goes down starting from initial value of 12 (1 second represents 1 hour count down for simplicity). 2. When night time counter reaches 0, the counter resets back to 12 and stops, then the blind opening motor activates and keeps running until the blind edge reaches the opening limit sensor. 3. The opening motor then stops, and the day time 12-hour count down starts. The day time counter operates the same as the night time counter. 4. When day time counter reaches 0, the counter resets back to 12 and stops, then the blind closing motor activates and keeps running until the blind edge reaches the closing limit sensor. 5. The closing motor then stops, and the night time 12-hour count down restarts again. The whole process is repeated again. Please find attached below the rough sketch for the idea. Feel free to either sketch the ladder logic or use PLC Fiddle (link above). Thank you.
  19. Hello all,    I have 3 kinetix 5500 drives connected in series but some how the 3rd drive lost power. all the fuses in the cabinet look good. nothing else is tripped either.    any advice is appreciated.  thank you   
  20. Hey guys,   I am looking to query a database through FactoryTalk SE.  I will be scanning packages, and using that bar code to find a lane assignment from the database.     My question has to do with where the VB script will reside in the FactoryTalke SE program.  I want this script to run at all times.  I see that each screen has a "VBA Code" but I am assuming that these will only run when the screen is visible.   Where does this have to be stored in order to run all the time?   Thanks In Advance!
  21. I'm looking for a serial device server, which will be a cheaper equivalent of moxa. Does anyone recommend anything?
  22. I hear a lot of people talking about the annoyance of price estimates (meaning they don't get a clear, transparent price from the beginning) and the costly engineering that seems to never end. Do you think that a step-by-step, clear process and course of action from A to Z would be beneficial for companies? And I'm not talking here about SCADA software, like Ignition. I'm talking about using Ignition to build and implement a fully working SCADA solution, customized to your company BUT you know exactly the price and the methods/processes that will be used (it's a replicable framework to get similar results for multiple companies - and the results would be a SCADA solution without the headaches of the unknown prices and engineering characteristics). Basically, a clear project-based approach rather than an hourly approach where things can get confusing.    Do you think the industrial space could use something like that?
  23. Productivity 2000

    Has anyone had the opportunity to work with Automation Direct's new "Productivity 2000" PLC? I have personally had the opportunity to use their "Click" PLCs which are, as advertised, very cheap, but effective. These little plcs are similar to Allen Bradley's micrologix line of processors, but definitely are not as well made. The software is free (a nice bonus) but definitely lack in features that you would get from the Rockwell folks. Still, for a simply job on a tight budget they work well. As for the new Productivity line, it looks (from a software side only) like many of the features you would find on the Contrologix and Compactlogix systems are now available. The user interface looks relatively clean and easy to use (Coming from an Allen Bradley background). So...any thoughts on the Productivity 2000?
  24. Good day,  I retreived the event log from 2x RM's today, I found on the one RM that there has been more than 700 million events. Apart from switchover events, there following event shows up a lot: (C2) Bridge Connection Deleted       Starts/Stops   Byte 1 (0xFF) : Byte 2 (0xFF) : Byte 3 (0xF2) : Byte 4 (0x13) : Byte 5 (0x0) : Byte 6 (0x0) :  Our system: 1756-RM2 1756-L75 1756-CN2R 1756-EN2TR 1756-EN2TR 1756-EN2TR 1756-EN2TR The CN2R's are connected to 12x 1771-ACN15 and 2x 1756-CN2R in remote racks, which is also set up to be the keepers. The EN2TR's are connected to their respective ETAPs/EN2TR's in ring topology.   We have experienced some issues when switching over. Hope someone can tell me what that message means regarding the Bridge Connection.    
  25. Hi everyone... I'm not a AB expert.. I'm using L74 controller, Rm2 redenduncy module,  EN2TR and EN2T module (on each chassis) on my control logix project and having 3 remote IO's rack on ring topology... I have use EN2TR for ring topology and EN2T for scada communication. The problem is my controllers are not synchronising on fibre optics... I have to connect both EN2T modules with one an other for controller's synchronisation. They are syncing over ethernet but not over optical... your help is appreciated    Thanks in advance
