  1. Anyone have any suggestions on the best way to pass a little bit of data between a SLC 5/03 controller and a compactlogix? The current problem I'm working through is the SLC 5/03 does not support Ethernet (only RS232 and DH485). So now I'm trying to find a solution.   Thanks,
  2. Dear Sir, Kindly Tell me how to use encoder with micrologix 1400. Thanks
  3. I am fairly new on this forum & PLC's, usually i read and get tips from here.I use a RsLogix 5000 PLC software. I am currently working on a project at home that requires me to read from a Access DB. What type of Instruction or method do i go about, initially reading from Access? I know Excel is possible It's an existing system. Add on functionality/feature. I am using a barcode scanner that will link up to a Access DB to verify the barcode is legit and send this info to a different system via PLC/EthernetThe access DB is used because its a older system, it uses that. So it is possible? and guessing from what your stating, its is more involved to get the system working eventually?PLC = A&B 1769-L23-QB1 CompactLogix Controller I am using FactoryTalk View Studio as HMI, do not have SCADA.I have a control logix chassis. Thank you in advance...

  6. WeinTek to AB PLC Issues

    YoungNDumb posted a topic in HMI & SCADA

    I am connecting a WeinTek eMT3105P to a CompactLogix L2 series PLC via the WeinTek Rockwell PLC (CompactLogix) - Free Tags driver and I cannot for the life of me get the thing to connect. I have all my tags imported and have played around with all the settings in the manuals I can find. Any help/advice would be greatly appreciated. I know my IP addresses are correct and if I connect my cable directly from the HMI to the PLC I still get the "PLC no response" message 
  7. Hello, I was hoping for some help in trying to read/write to a handful of bits in a CJ1M-CPU13 controller from a Compact GuardLogix. The CJ1M rack has a CJ1W-ETN21 card that is already communicating to a handful of Yaskawa drives. Is it possible for me to communicate with this controller from a CLX unit over ethernet? I don't believe an ETN21 card uses EIP but is there a way around this? Right now, I'm struggling to even find the IP address of the ETN21 card as the CX-Programmer file provided to me by the customer does not have the card in the IO configuration and I've never worked with Omron PLCs before. I found a CJ2M to CLX guide but it assumes communication over Ethernet IP and the ethernet port is native to the controller. Any help at all would be appreciated. Thanks!
  8. Hi everybody: I'm writing here because I have an Etherhet problem with my compactlogix 1769-L32E. I connect a crossover cable between my pC and the controller, then I run the BOOTDHCP server program . The BOOT DHCP window only shows the MAC of the PC, the controller´s MAC doesn't show even if i wait for more than 10 minutes I hope you can´t hel  
  9. Hey guys, I am working on an application that tracks irregularly spaced PET bottles on a conveyor line and then blows them into boxes waiting on the side of the conveyor. I believe I have working logic, but I am having issues with the encoder at operating conveyor speeds. I believe the best logic for my project is to use a photoeye to detect the presence of a bottle (a one-shot makes sure it is only detected once), and then "store" the "presence" of the bottle in a binary file using an encoder pulse to trigger a BSL function. Using this logic, the bits in the file are analogous to a real, physical location on the conveyor, and I can just monitor specific addresses in the file where my real-world air nozzles are located. My current problem is that as my conveyor speeds increase, the PLC begins to miss pulses from the encoder. During my initial set-up, I took data at very slow speeds to experimentally determine how many pulses were between the photoeye and each air valve, but when I run at full speed, I only detect about 70% of the pulses detected at slow speeds. Not good. Althought the "skipped pulses" seem to be proportional to the detected pulses at slow speeds. I am using an encoder that only runs at 60ppr, so I would think that my PLC (MicroLogix 1200) can handle this...I did the math before I purchased the encoder and thought I found the pulses to be infrequent enough that the PLC wouldn't miss any. My 2 trains of thought: 1) I need to use an interrupt for each encoder pulse since they occur so quickly (utilizing an EII), which I am not fluent in. I can find instructions to intitially configure the EII file, but I am unsure of how you are supposed to correctly set up the ladder logic to utilize the interrupt. 2) There is an electrical issue. The encoder I bought uses pull-up resistors. The resistor value I selected only drops the detected voltage to 14V from 24V. Is it possible that the encoder does not spend enough time in the "off" state at high speeds because of this high voltage value? OR does the usage of a resistor introduce a time-lag into the system which further complicates the issue? Any help would be appreciated, Thanks!
  10. I want to use an incremental rotary encoder with my Allen Bradley PLC to move induction motor (3 Phase) in clockwise and anticlockwise direction.Please help me with the program how to use High Speed Counter Values to move motor reverse and forward.
  11. We've purchased an Autoclave at auction with CompactLogix L32e and PanelView Plus 1000.  With the help of some forum members and a local engineering company we have the machine finally working! I'm looking for some advise as to how to train users for standerd operation.  For example:  Their is a toggle switch on the front which powers on everything (PanelView, processer, switch, etc).  We close at 5pm each night.. Should we Power down the machine each night, or leave it on? Another user mentioned a battery and I was a bit confused with the manual. With the machine off, Is the PLC only holding the program because of the battery?? I have backups of the following.. (.acd, .apa, .mer) files.  I also have created a Disc Image of the Internal Flash card on the PanelView.  Is their anything else I should have a backup of? Their is a CF card in the PLC.  It has a folder called "Logix" and one called "System Volume Information"  In the Logix folder is  a CurrentApp folder with a .bin and .p5k file.  Does anyone know what exactly these are doing?? Any other advise is greatly appreciated.  Thanks so much for your time.
  12. Good morning i want to know how i can recognize into the compactlogix 1769-L24 ER the micro 850 (2080-LC50-24QBB), because i want to communicate this two devices with MSG, i already i can see these two equipments into RSlinx but when i start Studio 5000 i don't know whick module i have to use it to recognize the micro 850, please help me
  13. Hi Everybody, I would like to get the Connections from an AB CompactLogix L32 with CIP. I can see these connections on the web interface. According to the CIP Vol1 v3.3 documentation I have created a reqest in java which requests the first instace of the  Connection Manager Object with Get_Connection_Data service. I captured the sent and the received packets with wireshark. I would like to ask the following: 1.) Is this the correct way to request the connections from the PLC with CIP? 2.) The response says that "Service not supported", is it possible that the PLC does not support this service or there is problem with the request? 3.) Is there any other way to get the connections (I/O and Message) from the PLC with a CIP reqest? Thanks for the answers in advance.

  14. FX5 PLC loses impulses from encoder

    plc.mitsubishi posted a topic in Mitsubishi

    Hello everyone!I have strange problem.I have plc, inverter (mitsubishi), incremental encoder (sick) and motor.When i set the frequency on the inverter about 1,5Hz, the plc correctly counts impulses, but every higher frequency causes the plc counts impulses incorrectly or doesnt count.  Above described things are happening at the rotation of motor in the forward direction. With a rotation of the motor to the rear, high-speed counter doesn't count the impulses.All the parameters of high-speed counters and PLC program i am sure there are right ( i'm using only instruction to start high-speed counting (HIOEN) and to enable interrupt (EI).  Input Response Time i had on "No setting" or 10micro-s and nothing.Type of encoder - A/B phase, HTL.PLC - FX5UPLC program - Gx works 3.Maybe somebody had similar problem? Maybe somebody could tell me where i need to look for the solve?   Thanks for help :)
  15. Hello guys, Newbie on this site. I am looking for a run time free Allen Bradley .NET driver. Basically a library (.dll) that implements communication protocols to Allen Bradley PLC's ( CIP, Ethernet/IP, etc.). Can someone point me in the right direction please ?.

  16. GOT1000&CompactLogix Tags

    Omar_ri_pre posted a topic in Mitsubishi

    Hello Im new using HMI got1000, Im trying to connect using Ethernet this HMI to a compactlogix, i already imported the tags, but i can't use any of them, because the gtworks3 says "you have to map the tags for set a device", i dont know what means map the tags, some one can help me please?
  17. I have a compactLogix L24.  It is connected to a network switch.  I also have an ethernet servo driver (KM AKD) attached to the same switch. The CL L24 IP address is 192.168.150.1 The Servo Driver is 192.168.150.3 In RSLogix 5000, I added an ethernet module.  I put in the IP address for the servo driver.  When I go online, I just get a connection error (Code16#0204).   I can talk to the servo driver using my PC on the same network (192.168.150.13), but the CompactLogix won't talk to it.  Do I need to install an external ethernet module to make this work, or can I use the existing ethernet ports on the L24? I'm stumped.
  18. Hey guys, this is probably a stupid question so I apologize if it is, but I have a PanelView Plus 6 700 and a CompactLogix L36ERM on one of my machines at my plant.  We have several different molds that run in this machine, so we have 5-7 different PLC programs that can possibly run in this processor, depending on which mold is in.  I'm planning to go to a single program with recipes, but I haven't had the time to set that up yet.  So we use the PanelView for troubleshooting, and adjusting process paramters.  On the main screen in the PanelView I have the time/date and also the program name.  What I have been doing is just creating a string tag in RSLogix 5000 that is the program/processor name (we use the same name for the processor and program) and then on my PanelView I just create a string display that looks at the string tag name in the processor.  That way anytime a mold is changed over and the PLC program is downloaded, the PanelView displays the correct program/processor name.   Now this is all fine and dandy and works as long as if a new program is created, we remember to change the string tag to the name of the new program, we often run new sample parts and what we do is rename an existing program that has similar logic and save it as a new program name.  The problem comes up because if somebody copies an existing program and makes a new one, the string tag is still going to say the name of the old PLC program.  Now if we only had one or two or even 5 machines, it would be simple enough to just remember to change that string tag.  Our, or I should say MY problem is that we have approximately 40ish machines in our plant, and I can't always remember to change that string tag every time we create a new program.  I should say that I have been, but there are times that I may forget. My question is this, is there any way that in FactoryTalk View ME Studio to have a string display the name of the processor or the name of the PLC program automatically without having to manually enter the name into the string tag that I created in RSLogix 5000?  Like is there a system tag somewhere that has the name of the processor or the name of the program?   That was way more explaining then probably necessary.  It's early and I've had way too much coffee haha.   Thanks guys.
  19. Do I need an encoder (slave) axis for my project? I am using a Powerflex755 and Incremental Rotary Encoder (scaled into linear movement axis)... Any other suggestions would be GREATLY APPRECIATED!! project file https://sites.google.com/site/lyncedrgb/eva/untitledpost-2/StellaPLC.ACD
  20. Hello All! This is my first post so please give my descriptions some lee-way please:P I am having trouble finding a solid example of ladder logic which integrates a: PowerFlex (755 in this case) Rotary Incrematal Encode ( or any encoder for that matter) A Prox to reset the resolution at specific points along the axis Also, can I use the standard Motion Instructions (MAJ,MAS,MAM etc) to control the movement sequences of the PowerFlex or are they only meant for use with Servos? I am working on automating a Lumber Treatment Process. The movements will have to move tens of thousands of pounds.. Therefore I would like to use the PowerFlex as a Torque Limiter to control a 15HP squirrel cage motor on a massive gear reduction. I have the distances and pulses per distance traveled from the mechanical engineering guys.. I'm just having problems integrating! After using the Setup Wizard for PowerFlex how can I go about actually inserting movement instructions for the drive into my ladder logic? Some more info on different movement profiles.. I've also included my attempt at trying to piece this together thus far.. Any input would be welcome! (StellaPLC) https://sites.google.com/site/lyncedrgb/eva/rslogix The actual drive and PLC are not available to be me at this time.. could this be an issue while trying to write this motion control program?

  21. Encoder input CP1L PRV2

    berge posted a topic in CX-Programmer

    Hi, I am planning to use an encoder on a CP1L to read on the RPM of a spinning wheel. For this, I can use high-speed counter 0, and the PRV2 instruction. My problem is that I also need the rotation direction. I was wondering if anybody had a tip for this? Thanks
  22. All, I have a 1769-L24ER-QBFC1B processor with a 1769-ASCII card that I am trying to get working on the bench. I have a standard serial cable hooked up from Channel 0 of the ASCII card to the COM1 port of my computer. All I'm trying to do at this point is a simple bare-bones hello world program with a terminal (termite or putty) so that I can verify my setup and understand how it works before I try to implement it on the plant floor. I have the card set up in alternating mode and am using the pre-canned program found starting on page 35 of the user manual(1769-um012) .This is my first time using the ASCII card I am familiar with the CompactLogix processors and the RSLogix Suite. Any insight you can give would be greatly appreciated. Thanks, Lucas
  23. i am working on CTL (online cutter)i am using fx3g plc with 1024 ppr encoder i want to calculate MPM(METER PER MINUTE) in real time with the encoder can some one help me with the logic and how encoder work in frequency mode
  24. Hi Everyone, I have a PowerFlex 525, in Velocity Mode with a Encoder Card "25-ENC-1". We are controlling this drive via TCP/IP with a 1769-L32. Through the PLC if I try to toggle the Bit for "Pos Redefine" in A560 [Enh Control Word] it instantly turns back to 0. But through the Parameter List Editor I am able to toggle A560. For My function I need to have the drive in Velocity Mode, If I change the drive to Position Mode I am able to toggle "Pos Redefine"   Any Thoughts would be great      
  25. From what I can tell, there is no built-in PLC simulator within RS Logix 5000, and I have to download a separate package that requires another licence to be paid for?   Is that really the case??
