  1. Hello, I'm using Allen Bradley Micro850 , 2080-LC50-24QWB. I wrote a program using Connected Component Workbench which reads certain indications and controlling contactors. My customer would like to connect that PLC to a PC by an Ethernet cable RJ45 and read those input registers and write those output registers into his application that he had built. He would like to know the commands in order to read or write the data and the TCP/IP data structures and frames. I would like to have the registers mapping of this PLC as well. i have been searching this information in the data sheets and have found none. i hope you could help me or at least instruct me becasue that's really urgent. thanks in advance.
  2. Hi, i uploaded program from my Allen Bradley 1400 PLC. when i tried to go online, a notification pops up showing program in processor has changed causing offline state do u want to upload, when i upload the same information comes up Uploading from PLC.pdf
  3.  Hi, after implement the following steps to configure my Allen Bradley 1400 programing logic controller, I tried uploading program from the PLC, a got a notification displaying (no respond from processor at selected path/node) please will appreciate any help to rectify this error uploading program from AB 1400 (1).pdf
  4. Hi  I have a MSG instruction which checks the status of the DLR network which I have attached as an Image below Message Type - CIP Generic Class 47 ,Attribute 0,Instance 1,The destination element is a SINT[57] called Services_DLR My question is, how do I interpret the results.  For example Services_DLR[1] is the network status, but I have seen a value of 0 when the ring is okay but I have also seen values of 1 and 4 and don't know what they mean. I assume 1 means ring fault but I do not know what 4 means etc. or  The last active IP goes to Services_DLR[17] but I would not of known this, only the code was wrote by someone else. (Image attached) On page 189 of https://literature.rockwellautomation.com/idc/groups/literature/documents/um/20comm-um015_-en-p.pdf I can see the DLR object but I dont know how this populates my SINT array or what each element is for so if someone could explain or point me to some documentation that can explain it to me, i would greatly appreciate it   Hope I made myself clear, I am new to PLC programming so just looking for some guidance   
  5. SLC-500 Power Supply Short?

    Anyone have experience with the old SLC-500s? I have one machine that is about 13 years old and I think they used a new old stock SLC-05/04 when they built it. Anyway I had a battery error, which makes sense since the battery was very old, and I lost my program when I tried to replace it, which makes sense because the capacitor which is supposed to hold the charge is very old. When I tried to re-download the program to the PLC, I could not connect, I realized my issue now was no null modem... and my driver not working on my RS-232 to USB converter. My question is:  What is the port above the DB-9 port used for? It was labeled PROG, so when my DB-9 serial cable didn't work I tried a serial cable for a mitsubishi FX series on the top port... and.... my power supply died. Is this a common thing on SLC-500 power supplies? Can you short them by using the wrong cable? The weird thing is the fuse on the front was not blown. Is there a fuse inside I can get to and replace? We are planning on just keeping this machine a few more years so we don't want to upgrade it. The CPU was fine afterwards.
  6. Hi all, I am new AB family, currently got into a new project but i have following doubts, Please clarify my following doubts. Project Details : I need  to implement 21CFR part 11 Compliance in AB HMI (1&2) -  2711P-T10C4D1 & 2711P-T6C5D As per my study, i understand that 21CFR can be imlemented by FactoryTalkView(FTV) ME edition V10.00. But HMIs currently available are programmed using FTV 5.0 version. Can we upgrade the FW version of HMI and convert the old HMI backup (from FTV 5.0) to new Backup (FTV 10.00) and load it  without disturbing the old backup HMI screens/settings ? So, Please give me solution .... If you have datasheets, documents, Videos also , kindly share with me. Thank You in Advance, Thanks & Regards, M.Monish Kumar monish.uatpl@gmail.com  
  7. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  8. I am needing some guidance on an application I'm working on. I'm trying to obtain data from a profinet slave device to an Allen Bradley compactlogix PLC. I am using a Prosoft PLX82-EIP-PNC profinet-/ethernet-ip gateway as a median to allow me to access the profinet data. In RSlogix5000, I have created an EIP Class 1 connection for the profinet controller and AB PLC (248 words of input data, 248 words of output data). The same structure is created in the profinet controller (248 words of input data, 248 words of output data). The profinet gateway and PLC are communicating properly. From my profinet slave device, I have a specification that the data is structured within a 23 byte format. Connecting to my profinet gateway, I can see this data. I have attached an image that shows the specification of the profinet data and the data values displayed inside the profinet controller. From the PLC side, I'm needing to be able to see this data and put it in meaningful values. I am using the profinet slave device's internal temperature as an example to work towards. I'm not sure the best way to be able to handle this data and structure it to a meaningful value inside the PLC. (I am using the device's internal temperature as an example to try and get into the PLC).   Thanks,

  10. Hello I have a problem with dl-ep1 ethernet modul. I connected the module to a IL-1000 sensor amplifier. There is some problem with the communication. How should I adjust ? I made some pic about the trouble. The sensor is a IL-600 laser distance sensor. I dont know yet how can I get the actual value.  Anybody knows how to set this modul ? If I think correctly after the right setting, if I check the sensor output:0 then, I can see the actual value of the IL-600 sensor. But unfortunatelly this part also not so clear for me, because I can connect about 15 sensor this ethernet modul.  Thank you so much if anybody help.
  11. Hi Guys, I need your various suggestion and helps on this issues. Past few days we facing an issues whereby the gantry of Z-axis which using the Kinetix 5500 servo drive straight crash down on the conveyor. The fault was Excessive Velocity Error and the first thing we took a look was the teaching and the speed. Somehow the teaching value of the motor and the speed was alright, we are running the axis on 100% speed. We have no idea the fault might be on the wiring or it might be the acceleration of the motor speed. We use to run this machine onsite at various customer, and this happens past few days. We run out of idea and we will be very much appreciated if there is any helpful idea could be bring up to. Steps taken so far; - Verify encoder value - Checked teaching position - Verify speed,acceleration and deceleration value was correct - Power motor connector was shielded  
  12. Hi my problem may have a simple solution but i cant work it out. I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC. Can you only use math instructions with whole numbers? is there a way around this? Thanks James

  14. Hello all. I have been working with an SLC 5/04 system, which houses various Digital and Analog INs and OUTs, up to Slot 29. I am currently mainly working with Slot 25, an Analog Input: 1746-NI16I. This is a system which has already been set up and has been running for the best part of 8-10 years. This particular card has had some spare inputs, one of which I am trying to connect to. In the Advanced Configuration, only a few Channels are actually "Enabled", and each channel is pretty much slightly different from another in terms of Input Type, Filter Frequency and Data Format. I am trying to set up Input 14, which is Channel 15, to "Enable" it, 4-20mA Input Type, Filter Frequency of 6 Hz and Data Format of either Raw/Proportional or Engineering Units. Now, after I have made my choices, I click apply, and then OK. I am then confronted by a pop-up which states: "Configuration Rung and Data Integer Data File Number: 25 Integer Data Element: 100 Rung to be inserted: XIC S2:1/15 COP #N25:100 #O0:25.0 24 At Program File Number: 4 82" I have the options of OK or Cancel. If I click OK, I now have LAD 4, Rung 82 Highlighted. This First Scan Bit and COP function were already here, but does that mean I have now altered what is being written to "#O:25.0"? I now Download the Changes. However, after all this, I am not getting any Analog input reading coming in from the Live PLC. What is this COP function? What does it do? How do I properly set up this Analog Card?   Thanks for your time, -Jame
  15. Average motor speed

    Hi Guys!   There is a task. I have a motor, and I can monitoring the actual speed. The question is how can I to determine the average speed, if I know just the actual speed. If the speed is zero, it must be ignored. So I have to measure when the motor moves. Anybody have any idea? How can I solve this problem. RSLogix 5000.  Thank you.  
  16. recover program from plc-5/15

    A machine was bought at auction which included PLC-5/15 module.  It did not come with a backup of the program.  Our maintenance technician said the program would not load and turned the module over to me (IT).  I notice the battery was installed in '92 so am assuming the program is lost.  Is their any internal memory or last ditch effort i can attempt to recover the program from this module?

Is there any set up or can i upload from the memory card attached to hmi. The HMI has a glare and display is not visible, we are trying to upgrade to panelview plus. Thanks  Model 2711-B6C10x FRN 4.48
  18. Hello I am  a Robot Programmer. Fortunately  I would be beginning the PLC Programmer Interview Process. From Initial CV Screening and first round of Interview. Screening was easier. But unfortunately I am not good with PLC tech questions apart from that is involved with Robot Programming. I need a few questions to judge whether the applicant is faking his experience or does he has the qualities. If any PLC Programmers can help me, It would be a great help for me.   Thank You
  19. Flex I/O Rack

    I am in the middle of doing a retrofit for a old PLC5 and i decided to upgrade it to a Control Logix. With how much I/O I was needing the price of the system was going to be very pricey. So I decided to use my main rack as a control logix and use Flex I/O for my remote racks. I have never put together a Flex I/O rack so I am unsure of what I need for this rack other than my I/O modules and a communication module. Could someone give me a list of what is needed for these systems? 
  20. Problem with array

    Hi Guys! I have a problem with data collection. I use RS Logix 5000 software. I need to collect 11 int value. The sampling frequency is about 2 or 3 second. I tried to make an array but I faild, because I dont find what is correct for my task. I need about 5000 sample each of int value. Anybody have any idea about this problem ? If I have the datas then I have to exporting to an excel table . Thank you if anyone can help me.   T
  21. I have G310 and need to communicate with a AB PowerFlex 753 via Ethernet (20-COMM-E). I have tinkered with the Allen-Bradley drivers, which appear to be a MSG function, with no success. Has anyone done this?
  22. I have multiple PVP 1500's on the same network. From the one in my control room i need to be able to see what user is logged into what HMI. How would I address the system tag of another HMI on the same network would I use the IP address? thank you for any help in advance
  23. load cell SP4M-7Kg

    Hello guys, I have a system of 3 load cells (SP4M-7Kg) attached  to a Micrologix 1500 analog inputs. in the same PLC i have 3 coils for a vibrator, each vibrator is working with signal generators. and the load cells with an external 24vdc Power Supply. i see my load cells readings fluctuating too much even with the vibrator not working. if it is set lets say 70 Grams it is jumping from 68.4 to 74.8 going up an down never never stabilizes in one number, so i suspect am getting noise somewhere put a 100uF capacitor PLC inputs for the load cells but weight just increases more and more. How can realize where is the noise comming? what can i use as a filter? how can i improve this system? should i changed it to digital?   any help welcome! thanks.  questions?    
  24. Jiskoot modbus

    Does anyone have experience with a Jiskoot Insight controller? Im trying to establish communications between it and a MVI69-MCM. I have checked and rechecked all my settings. I am not sure what I am doing wrong. Thanks
  25. Hi everyone, I just want to layout the structure of the question. I have a GOT2000 (GT27* series) that I have hooked up and communicating with an Allen-Bradley PLC. I have established connection and can pull out certain tags values from the PLC program in RSLogix 5000. While I can read the tag values, I cannot modify them (in certain conditions).  So let say that I have a User-Defined Structure named "Smoke_Detector" and here are it's available members: Smoke_Detector:   - ALARM (BOOL)   - ON_TIME (DINT) * DINT in Allen-Bradley but Signed Binary 32   - Battery_Life (REAL)  My question is that while I can read and display the tag and its members through the following:   - LAMP for Smoke_Detector.ALARM   - Numerical Display for both Smoke_Detector.ON_TIME and Smoke_Detector.Battery_Life But when I tried to modify the values via a Bit Switch or Numerical Input, it does not operate on them.  However, if these tags are members are just standalone tags, meaning that they are not within a UDT in RSLogix 5000, then I can operate/ modify them just fine.  Here are the things that I have tried: * Making sure that the permission are set to Read/ Write in RSLogix 5000 * Making sure that the tag definition in GT Designer 3 follows the structure where @[channel]:[Network #]:[Station #]::[Tag instance and member (e.g Smoke_detector is the instance and Alarm is member] Any possible insight and input are appreciate!
