  2. If anyone can help me with this, I want the machine only get into run state whenever there is an User logged in. If no user logged In and trying to operate something I will prompt an String message 'Need to login first'. and If logged in/logged out status i want to monitor on PLC. Though IN panel view it doesn't allows to operate  anything if not logged in but I want to monitor the status on PLC.
  3. Hello Everyone guys, Did anybody has used the 1734-PLM Starin Guage Input card from Helm Instruments for Contrologix PLC? HELM instrumenst gave a set of instructions for calibration of the loadcell at first but it doesn't works, HELM instruments is helping me on this but just in case if anybody knows anything about it. I have checked the wiring and it is correct. WhatsApp Chat - Ken helm.zip
  4. Hello, I am new to this forum. I have been finding great information here and elsewhere, but so far not exactly what I am looking for. Has anyone used a Micrologix PLC to read messages from a large number of other micrologix PLCs? I have used this instruction successfully with serial and Ethernet communication but only with up to 4 or 5 other controllers.  One constraint I have already run into is the max size for data words in this processor of 10k. I was able to reduce the number of words I was reading and at this point am using about 2k for the interger files to be populated. There are 24 integer files with 80 elements each. The other issue is with the amount of data each RI file uses of 24 elements.  The idea in this application - which is a water utility - is to have all data exist at all sites. I was originally going to use the Maple Systems CMT3261Xv2 HMI which is installed at each, to poll all the sites, but I don't have a high degree of confidence in its ability to do this based on bench testing I have done. I will keep working with Maple tech support to figure that out. But I also need some of the data traded between PLCs for other reasons, so having all the data in the PLC registers is a bette solution if I can make it work.  Since each PLC needs to have data from each of the other PLCs, having a master read and write to all the sites would overwhelm the processor in terms of data used (24sites x 24 MSG instructions per site x 24 words per MSG instruction = 14k words). Also, I don't want to write all that code, since with the ML1400 I don't believe there is a way to use indexing on the MSG instruction. (I could use a Compactlogix as the Master, but presently don't have that in the budget. Also, by using another ML1400, if the master PLC goes down for some reason, any other PLC could become the master.  So my solution is to have the master read the 80 words from all 24 slaves into each apointed integer file and then have each "slave" read data from the master for each of those integer files. That will use 80x24 words for the integer files and 24x24 words for the MSG instructions for a total of 3k words used. The rest of the application uses little data at each site. But by having each slave read 24 data files from the master, I can just copy and paste the routine into each slave. I have already created a template for these sites, so I would just need to include the proper messaging routine.  I have 10 ML1400 PLCs for bench testing, but I am worried that having all 24 in action might create problems I am not forseeing. For example, is it possible that having 24 processors read from one processor in an unregulated manner would cause data collisions? I know it is Ethernet and that is less of an issue, but I just don't know. I also don't know how I would regulate it. In the past I've used timers, but I don't want to slow things down since there are so many messages.  I also don't know the best logic to use for the messaging. In the past, I have used cascading logic in serial communication where after one message is done or errors it triggers the next message and the last message triggers the first. Then I had a watchdog timer to restart the routine if it got hung up for some reason. I have seen many examples where one rung has the MSG instruction and the next rung has an unlatch instruction triggered by DN or ER from the MSG instruction. Presumably when the first 4 buffers fill all the rest would be put in the que, but again, I am not sure what unexpeted consequences would occur with that many messages. I don't know what is the best practice. I have yet to find examples of this online or with Rockwell.  The physical layer is high-speed internet using a dedicated LAN for the application. We are using fiber for about half the connections and Cambium gigabit radios or 900mHz radios for the others where the lowest throughput is probably 1mbs, but most connections are over 100mbs. The plan is to be able to monitor and program each PLC and HMI remotely once the system is operational.  Thank you in advance for your consideration and expertise.   
  5. Hello everyone, now we are using Kinetix 6000 Multi-axis Servo Drives and TPM 025S – 031V – 6PB1 – 094C – W5 servo motor from Wittenstein, the main function of the servo motor is to elevate the welding module up and down. Several months ago, the servo suddenly increased the torque by 50% compared to normal state, which caused UPS several times in a shift. we went down to the machine and found out the locating pin was worn out and misaligned with the main transport plate. We replaced it and the torque went back to normal due to the welding module was aligned with the main transport plate. The E64 fault started to appear after this problem and still on till now. We did something that we thought can solve the problem: - Upgrade the PLC Logix L73 to L83 but it's not compatible with system so we keep using L73 - Replace the servo drive to the new one - Replace all the cables, check the connection if it was right or not - Check grounding, it was normal - Check the physical components connected to the servo, everything was ok - Measure vibration of servo motor & magnetic field - Replace the servo motor with the new one - Check looking assembly and alignment - Invite Rockwell and Servo expert to the site All the things we do but E64 keep showing so we bypass the E64 by changed feedback noise to status only and the system continue to work. Has anyone experience this before and can you share what you do to solve this. We want to eliminate the E64 completely so the feedback is true and we can we know the true root cause when it send signals, thank you everyone.
  6. 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
  7. 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,
  8. 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. https://www.youtube.com/watch?v=kV0nXSyM7Gg
  9. 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.
  10. 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.
  11. 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. 
  12. 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!  
  13. 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: https://imgur.com/a/PEPI4Wl      
  14.   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?                                    
  15.  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. 
  16. 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?
  17. 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
  18. 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   
  19. 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!
  20. 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.    
  21. 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
  22.   Mail me for Help if anyone is stuck during coding and settings.
  23. I have a 2 CompactLogix PLCs running right now, communicating CIP Safety and Standard data over Ethernet I/P.  For reasons I can't explain right now, the IP address of the second one HAS TO change semi-randomly (the 1st PLC is static).  Setting the 2nd PLC's IP to static or assigning it a static DHCP address is the obvious solution, but for the purpose of this question, that cannot be done. Is there a way to programmatically change its IP address on the 1st PLC's program?  (There is an HMI attached to the 1st PLC and adding a screen to enter in the new address would be trivial.)  The only bit I'm still missing is how do I change the IP address on the module in the 1st PLC so that it's pointed at the right IP address of the 2nd one when it changes.    I found instructions on how to use msg instructions, but that hasn't worked yet.  Any help would be appreciated. Thanks!
  24. Hi,  Can someon help me with the following question. Like what makes a Kinetix 6000 drive a Guarded drive ? What type of safety stuff can you set to make it more safe.  Is it some parameter ? I am bit confused, by the manual. Should I active it in the PLC program or how ? Or it is some setting like a safe speed or torque.  I would really appreciate any help. Thank you so much ahead.  Have a great day, thanks for the reading.
  25. I want to take data from an AllenBradley SLC 505, and send it to an Omron NX102-9000. Specifically F8: 46 from my SLC 505, which is a temperature sensor. Both PLCs are on the same Ethernet network, each with its own IP address. Have you tried it?
