  1. Dear Experts In our plant, we have only one Allen Bradley PLC (Compact Logix L24ER) in one of our testing machines. We need to check online reason for error :LH Motor Negative overtravel Please let us know if it is possible to get communicating software RS Logix 5000 for trial Regards  
  2. Hi, I'm looking for help with the string exchanging between GT25 and AB CompactLogix. I'm reading recipe data from SQL via MES interface to the local devices such as GD3000. I want to move the string held in the registers GD3000-3009 (20 characters) to the string tag in the Allen Bradley. The problem is that in the scripting I cannot enter the AB Tag, because when I imported the CSV with the string tags their data type is STRING, and the scripting in GOT accepts only numerical datatypes such as WORD, etc. Has anyone found a way to handle that?
  3. This may be more of a Zebra question than a PLC question but I will post it here. I am using Zebra's Network Connect to enable communication between a CompactLogix L13ER and a ZT410. My issue is that the QR Code omits the 5 elements of the array in Field 1 of the CompactLogix. I expect the first two elements in the array to be ignored per the manual but the first 5 has me puzzled. All the characters in the text shows up fine. I have attached what I am seeing. If you have a QR Code reader, you can scan the QR Code.
  4. Dear Colleagues,   I require some help with regards to setting up virtual machines, We have some ControlLogix 1756 PLCs scattered around site running on different version (v20, v21 & v32). My company requires all software installations on company computers to go through IT. Installing all these versions on single PC is really a pain (going through IT)  for new hires and for new PCs. I am trying to suggest using virtual machines for each version that can be shared/distributed among the engineers and also to give engineers some autonomy in the VM environment.    How do I go about this especially with respect to licensing without violating the terms of use both the operating system and the automation software? 
  5. I am trying to communicate power flex 523 drives to micrologix 1400 directly through DSI using 1763-nc01 cable. I have considered channel 0 in plc as modbus RTU master and trying to connect but not connecting. So am i doing it correctly. Any suggestions?
  6. HiI have just bought a new AB CompactLogix 5380 (5069-L306ER) labeled "FACTORY SEAL".When I trying to connect via USB or Ethernet on studio 5000 softwares, no matter RSlinks or BOOT-DHCP tool, there is no responding at all.I know these PLC shipped row and there must be flash before using for first time, But I think when I turned it on via MOD Power, while connected to PC, there must be some sound for connecting via USB cable, or some activity in small led's of Ethernet port in both sides. but there is no response at all.I'm begining to doubt about my cables, although the USB cable and the Ethernet cable are standard cables, I try it with two or three cables.P.S: The package does not included a SD card, I put a SD card from my own, Could it be problematic?Thanks.
  7. Hi there! I've created an Android app to read/write data to Allen Bradley PLCs via serial DF1 communication (a Bluetooth serial RS-232 adapter is required). You can use it to read and write Binary (B), Integer (N), Float (F) and Long (L) data files to a MicroLogix or SLC500 PLC. The app is now an open testing release in Google Play and I really appreciate any feedback. Youtube: https://www.youtube.com/watch?v=klYEuzdNBNg Google Play: https://play.google.com/store/apps/details?id=com.facsocubac.df1polling&hl=en_US&gl=US Some of the features (such as Write data to the PLC) require to upgrade to the Pro version. If you wish to upgrade, just send me an email and I will send you a promo code so you can test the full app for free. Thanks a lot for your help Facso
  8. Hello All, I am new to Studio 5000. I am trying to have my limit sensors energize my stop output, and also have a manual bit that I can toggle that will energize the stop output as well. Currently, toggling my manual bit works for energizing the stop output, but my limit sensors turning on does not energize my stop output. Not getting what I want with or without the ONS. What is going on??? Thanks, Daniel

  9. CJ1M con CJ1W-EIP21 a ControlLogix

    Eduardo Juarez posted a topic in CX-Programmer

    Hello I am trying to communicate a CJ1M with a CJ1W-EIP21 Card, with a Logix Control, but I have not been successful, what I am looking for is to read data, from the OMRON and see it in the Logix Control, but I have not been able to establish communication, I am looking for someone You will already have a functional example, with the backups of both PLC'S, to be able to observe how they made the configuration. Thank you for your support Greetings
  10. Hey guys, I did a quick search here and didn't come up with anything, so hoping I'm not asking something that has already been answered. I'm looking at automating an existing plant which currently has zero controls, so starting from scratch. The process isn't complicated but the equipment is a bit spread out over a two story facility. We're thinking about using a CompactLogix 1769-L32, physically located as central as possible, with ten four-slot 1734 Point I/O blocks. My concern is that many Allen Bradley controllers limit the number of I/O modules you can add to the project. Like some 1756 controllers are limited to 30 local and remote I/O modules, CompactLogix controllers may be limited to 16 local and who knows how many remotes, etc. I can't find anything that spells it out explicitly in the Design Considerations Manual. The CompactLogix 5370 User Manual only says it supports, "a limited number of Point I/O modules that can be used as local modules". Nothing about networked modules. The CompactLogix Selection Guide clearly defines the number of network nodes, but nothing about the number of modules. Does anyone have any direct experience with this much Point I/O in a CompactLogix environment? I'm thinking that we're in an age of counting nodes, rather than modules but don't want to order the hardware without being 100% sure.
  11. Hi: I am trying to determine if I should use the RS 5000 or RS 500 to start a micrologix 1400 project that will include a Maple Systems HMI. I have never used the RS 5000 software so I am aware there will be a learning curve, however I am certain that it could be useful in the future.  However, my work schedule is nights so I am limited in how much tech support I will get here at my facility when no one is using RS 5000 here at this time? Your input and feedback will be greatly appreciated. Thanks in advance.  
  12. I'm trying to connect a SMC EX-260 to a Allen Bradley Micrologix 1400 PLC so  I can run some valves with it. However, RsLogix 500 doesn't allow me to just setup a generic ethernet device like I would on RsLogix 5000. Is there a way I can communicate these devices together so I can use the SMC Valve system with my Micrologix?
  13. Looking for some help that i cant seem to find online - I have a  CompactLogix 5370 L1 Controller part number 1769-L16ER-BB1B and would like to connect a 1769-IF4 and a 1769-OF2 Analog expansion modules. Rockwell sales tell me they are compatible The Compactlogix looks to be a "slide in" and the expansion modules are Plug Type. Is there a cable or base rack I can use? Thanks in advance.
  14. I'm trying to send an int over TCP using a MSG Socket,  Compactlogix ==> Arduino Ethernet Shield I have set up TCP communication between two Arduino Uno's using Ethernet shield. I've set up the one as a server, the other as a client. server IP: 192.168.1.21 port 23. If the client is connected it reads incoming data as a byte or an array of bytes. The data between the two has been verified to work. I'm now trying to transition the communications between a compact logix-L32E. I'm looking to send a byte (or int being as there's no byte data type) from the Compactlogix to the Arduino using TCP. To my understanding I need to use a socket create, open, read/write, close. The manual to do this is vague as a step by step procedure. Does anyone have an example code for socket programming? I can open rs500, rs5000, and studio 5000 programs. If I can open a file to use as a reference I can translate it on my own. Any help/advice would be greatly appreciated. 
  15. Hello all, this is my first post. I am using an AB Micrologix 1400 (1766-L32BXB Ser C FW 21). I was trying to generate a pulse train using the PTO instruction. I have modified PTOX funct. file. The ladder is just a simple XIO followed by PTO, (The Quick Start ladder from 1766-RM001). When I looked at the output waveform on my oscilloscope, I noticed that it wasn't a square wave. I decided to run it at several different frequencies to see how the wave form would change. At 10Hz i got a square wave. As I increased the frequency the falling edge became sloped and almost horizontal. Is this how the output should behave? The data sheet indicates a max frequency of 100kHz, but at frequencies over 150 Hz. The wave form looks like the output of SMPS. 
  16. I have a purchased Machine that came with a Siemens LOGO 8.FSR PLC (Smart Relay). Generally we use Allen Bradley or Mitsubishi. Anyway, we need to communicate data between the LOGO and an Allen Bradley Compact Logix.  I do not desire to add an additional network to the AB but as best i can tell the LOGO is exclusively Modbus TCP/IP. Has anyone come across a similar situation?  I look online and did find an  Anybus module that claims to be able to link them together.  Looking for anyone who has faced this challenge and succeeded, or failed.   Thanks
  17. We have been working with PLCs for long time. We used to develop PLC logic, partly test it on an emulator and test the rest on the partly energised equipment. From time to time working with computer software development (C# and JavaScript) I was always looking for something similar to unit testing in the PLC world. As I couldn't find anything at that time I've started developing own automated testing tool. Now we use this tool, which basically simulates PLC inputs in defined actions and checks expected behaviour of internal tags or/and PLC outputs. If it behaved the way we expected, it's PASS, otherwise it's FAIL. We break complex logic into small parts and create unit tests for it. By creating more of these unit tests we can test PLC logic of any complexity. The software called PLC Logic Prover and it's free at https://www.controlx.io Recently, I've been told that there is no point to develop anything new if there are already great tools on the market. Honestly, I didn't do proper research earlier, so I'm here asking the experts. What do you use to test PLC logic? What automated testing tools do you use? Is it using IO simulation or it can test logic by other means? Your replies are appreciated. Thanks, Alex
  18. Hello All, First time working with PLC. Get the hang of it from stuff I researched. Having an issue with an axis setup for a servo motor.  When I try to do an auto tune it gives me an error that axis is not configured.  Source: Config Fault    Condition: MotorDeviceCode- INvalid attribute      ACtion: Immediate Stop Fault Entry: Type 8, code 9 subcode: 1314 stopaction: 4 Statechange: 3   I was wondering what am I doing wrong? Any leads or source information I can use to solve this. 
  19. Hi, got a mental block lol.  Got a machine we are modifying, currently got most of the code in place. Working on a fault routine now. This machine doesn't have an HMI or wide array of PL. Nothing major just a simple vision system check. Currently have 6 faults that will stop the cycle running. I'm wanting to have the beacon light (Red light) blink for the cause of the fault. For example: Scenario 1- Fault stop for bottle check NG:  (two) .5 sec blinks -  2 sec red light off -  (two) .5 sec blinks ..... repeat  Scenario 2- Fault stop for bottle check NG and reject sensor blocked:  (two) .5 sec blinks -2 sec red light off - (three) .5 sec blinks - 2 sec red light off....... repeat I have the code a few different ways but it looks "dirty". Any suggestions? Thanks in advance  
  20. Is there a way to monitor the Temperature of a Servo Motor on Allen Bradley Servo motors... MPL? PLC: CompactLogix 1769-L30ERM Drive: Kinetix 6500   Motors: MPL-B310P-MJ72AA, and  MPL-B560F-MJ72AA I would like to be able to monitor the temperature, and flash a warning screen on the HMI if the Motor gets too hot, or perhaps shut down the operation before the Motor overload trips. The drive and PLC are connected through Ethernet IP What I don’t know is if that Motor heatsink temperature information is available to the PLC.
  21. This is a bizarre one... CompactLogix, 1769-IF8 with 1492-AIFM8-F-5 wiring system. My client has reported several instances where one of his flow rate displays is frozen at its maximum value.  Each time, I have gone to the site, found that the value in the analog input tag is at full scale, and measured more than 20mA at the input - as much as 28mA!  I measure it using a clamp-on meter and I measure it at the input module (1769-IF8) and the external, pre-wired terminal block (1492-AIFM8-F-5).  I cycle power to the PLC.  No change.  I cycle power on the transmitting device.  No change.  I disconnect and reconnect the input (signal wire at the module or the terminal block) and everything goes back to normal.  This has happened on multiple channels on multiple input modules and with two different types of transmitters. I didn't install this system, but it seems to have been done properly and it had been running fine for many years.  These problems just started happening out of the blue. Has anyone out there had any similar experience?  This is a new one for me after more than 25 years in the business.
  22. Hello, I am trying to receive data from a scale via rs232. my setup; compact logix l18er with a 1734-rs232ascii point IO module to receive the data. I am receiving data from the scale, but I have very little understanding of ascii, so I do not know how to convert the data I am receiving to something use-able. any help on how to convert the data to something I can use or where to even start would be much appreciated. using a scientech ZSA 210 scale https://scientech-inc.com/media/downloadable/files/links/1/2/12222-d_rev-f_instruction_manual.pdf
  23. My project is to read an RFID tag (ascii) with a Micrologix 1400, send the string to a PC using Ethernet/IP, lookup and compare in an Excel spreadsheet, and send back data (probably an integer) for the plc to use to control direction. I have to scan and compare an RFID tag to a list of 1400 possible part numbers, at different locations (more than 1 plc). I want the several PLCs to go to a single PC to make it easy to update when changes occur (on a weekly basis). Has anyone done anything like this? I'm assuming there will have to be some kind of vb or c+ application involved.   Thanks,  CK
  24. Hello guys, I am running an application for packaging measurement using a sick DFS60B incremental encoder (programmable from 1 to 10000 PPR). In more detail, it passes packaging on a conveyor belt and we have created an inspection station and an expulsion station (defective packaging), so we use the encoder to check at specific points of the packaging for defects (we use special sensors to check defects). ) (there are four in total). However, the problem we are having is the following: When reading the encoder in the PLC, the same means that performs "jumps" and does not enter the windows (GRT and LES) created on the ladder, ie, as if it were not continuous. . I understand that because the VHSC24 card works at 1 MHz in counter mode, this type of problem should not occur according to our application is not even 100 KHz. For example, our case: Using 1000 PPR and the motor speed (coupling output) is 3600 RPM (in practice it is around 1750 RPM) the frequency is calculated as follows: F = (PPR X RPM) / 60. : F = (1000x3600) / 60 = 60 KHz, ie 60 KHz is much less than 1 MHz, I think this kind of problem does not occur. Application Info: . Studio 5000 V31 . PLC Model: Rockwell 1769 - L19ER-BB1B CompactLogix 5370 . Encoder Card: 1734-VHSC24 / C . Incremental Encoder: Sick, DFS60 up to 10,000 PPR and HTL Electrical Interface. Using a 200 mm circumference / perimeter wheel. . Motor Nameplate Data: 1670 RPM, 0.37 kW / 0.5 HP, 60 Hz . Inverter: Weg CFW500, Output Frequency 62 Hz. Card Settings we use RPI: 2 ms Type: Counter, but we already use it as Encoder X1 Store Count Mode: Disabled Filter: No Filter, but we use 50 KHz and 5 Khz filters in our tests. Counter Attenuator: 1 Wiring Diagram VHSC24 We turn on encoder A at input 0 and encoder Aret at input 1 In logic (Structured Text) Using the PMUL instruction to convert encoder (Pulse) data to mm scale. (Ladder) The window comparisons part (GRT and Les) and other part of the process. We emphasize that we performed the tests also only with the reading and comparison part of the data, excluding the other parts, precisely to verify the issue of Scan, but the problem persisted. If anyone here in the forum has some information that can help us, I would appreciate it.
