  1. i need help

    Dillon's stickers posted a topic in Allen Bradley / Rockwell Automation

    I need help programming an allen bradley 2711R-T7T touchscreen. I'm using a micro 850 PLC and I cant figure out how to use the momentary PB on the screen to make the light on the screen turn on. I can turn the light on with the PB that is on the panel door but not the one on the actual screen. Any tips or suggestions would be greatly appreciated.
  2. Hi, I'm a long time lurker and would like to start by saying thanks for all the help over the years, much appreciated!  This is my first post, please be gentle. I'm working through a large project with an L83 (V28) including 75 EIP nodes & 5 servos.  We have a need for quick real-time response of 2 cameras during a quick servo move (taking several pictures).  I've broken my program up into a few event driven tasks (allowing me to chose the execution time interval (5 to 8 ms for more important tasks and 20 ms for less important tasks, etc.)), along with these I have 2 periodic tasks: 1 for my HMIs & faults running every 30ms and 1 for this quick real-time response camera situation running at .5ms which contains my camera and servo logic.  Everything is running well and seems responsive and repeatable enough, but I am now adding the second half of the logic which will essentially double everything (2 up system).  This has made me consider the best structure approach: Is it better to have a few larger routines within a few larger tasks or better to have more smaller tasks containing an abundance of smaller routines or some other different mix? Thanks, JD43    
  3. Hello, I am hoping I can get some assistance configuring an Allen Bradley PanelView C600 (2711C-T6C). All a long I have been able to communicate with the HMI using Ethernet protocol, but after I switched communication settings to what my Professor recommended by using the Panelview software, the Ethernet connection seems to have stopped working. The HMI has now been reset to the factory settings (by pressing ctrl + shift during start up then selecting F1 when prompt appears asking if the user desires to return to factory condition of terminal). Once the terminal resets I am able to eventually get to the configuration screen. When in the communication settings Protocol says "*", Status says "Unavailable", I've changed the device name to "plc" and the Node Address says "0". When I click on the "Ethernet" option the IP mode says "DHCP" then the IP Address, Mask and Gateway all read "0.0.0.0". I get into CMD/DOS PROMPT on my laptop while the terminal is connected to my laptop via an Ethernet cable and type in "ipconfig" to see if my laptop is communicating with the terminal but it is not. The lights where the terminals are located are also not blinking. After plugging in several different Ethernet chords from the terminal to my laptop I am convinced the issue is not the cable. I've tried resetting the terminal several times as well and I'm having no luck. Can anyone assist me with regaining Ethernet communication with the terminal or some work-arounds? I see there is an option to use the USB but it looks like AB no longer provides the drivers on the website. If it helps, the manuals I am using are 2711C-UM001 and 2711C-QS001.
  4. HI guys, does anyone here knows the data logging format for plc AB 1766? I had looked into manual but I cant find it,may be i'm miss look it.
  5. I am currently working on a fwd rev motor control routine, we have all of the circuit wired up and verified the physical circuit is working as intended when manually jumped. But will not turn the outputs on...  I triple checked my logic and it all seems right, all inputs are true all the way to the output on both the fwd and rev rungs. But still the outputs won't go true. if I toggle an output bit it does show up on the dc out card, I haven't tried forcing anything.  No errors or warnings, fuses are fine. our teacher does not help as much as we'd like and we have troubleshot just about everything we can think of with our experience.    Any input would be appreciated, thanks.
  6. 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 ?.
  7. I have just started programming PLC's and the first thing I have came up against is a 4-20ma signal to a analog card for a Turbidity meter. The problem I am having is the reading is very erratic. Is there any way to get it from jumping around so much?

  9. Hello,   I am looking for examples on using serial communication with a WMS inside Studio 5000.  Sample programs would be ideal. And I would like to get some information on what blocks need to be used. e.g. Send, and Receive   Thanks!
  10. Hi, I,m new to this PLC. I,m trying to set up 4-20ma signal on this controller but having no luck. I,m reading a level off a unit that sends out a 4- 20ma signal and i,m terminating in straight into my PLC but it doesn,t read at all on my ladder logic. I have set up 4-20 on analog properties . I have terminated it into 0in - and Iin - .Do i have to have 24V supply on CJC+? or am i missing something, any help??
  11. Hello everyone ! The plant where i work uses allen bradley CompactLogix 5000 controllers. It has three controllers, each one controlling a seperate production line. So my superior asked me to add a functionnality to the existing program, and after a little research, i found that it is better to edit the program in "Online Mode", and that's what i did. After that, i wanted to associate the new tags i created with some views in RsView Studio, but i cannot find any tags in the online folder associated to the controller, even though the connection shortcut is set and is working, and the online folders of the other two controllers contain all their tags ! Any suggestions please ?
  12. Hello,  I am trying to program an assembly line for two kinds of product manufacturing. This products would be manufactured in a random sequence. I have 3 station in the assembly line and would like to know how to transfer data of product from one station to other station and reset the previous station. The manufacturing is high paced.  the sequence of manufacturing is as follows:  Part type 1 : The part is placed on station 1 and procedure is carried out on 2 and 3 and the part is taken out. This is the current process.  We would be adding one more variety of part.  Part type : It is scanned on the first station and an extra procedure is being carried on the third station.    I want to take the data from station 1 and carry it over to station 2 and 3 respectively. and reset the station as it passes that station.  Please let me know if you have any ideas. I have tried daisy chain programming but that might not work .

  17. Hi, I am new to Allen bradley PLCs We have an application where a compact logix communicates with our SLC505. Both PLCs write or read data. Need to send 8 word data and receive 7 word data based on Sequence timing. Would like to establish this using EEM Instruction. Please let me know what are things I have to take care while using EEM Instruction. Appreciate if some can send me a PLC Code using EEM instruction multiple times in a program or can guide me.

  20. Hi everyone, First time posting here, sorry if I screwed up any rules on this forum. I have a logic file that was created two years ago. I'm using RSLogix 5000 version 20.04. The customer has owned it for two years, and I just got the latest copy back from them to do a kit. So when I go to save my changes (offline), I get "Failed to save the project as 'filepath'. An unexpected CTree error occurred." Error 753-80042211. (see attached screenshot) I tried searching this error on google, with no results. I went to the help dialog box, which wasn't helpful. (See second attached screenshot) I can't think of anything else to do, my boss is gone until two weeks from now, the other guy in my department has less experience than me.   Can anyone think of a way to fix this? Otherwise I'm completely stuck. Don't think my boss will be happy with me getting nothing done for a week.   The help file says: Error saving the project to a different file An attempt to save the project to a different file failed. The error message you receive indicates one of the following conditions: Name is badly formed The name does not follow the IEC-1131 Name standard. Enter an IEC-1131 compliant name. >>> I tried the name "test" with no success Access denied If the file already exists, make sure that you have read/write privileges to it. >>> It is not set to read only or anything of that sort In use by another process The file is being edited by another process. Close the file in the other process if you want to save over it. >>> Tried making a copy to my local drive, opened that one, still won't save Path doesn't exist Make sure that the path exists. If you are saving to a network drive, make sure that you are still connected to it. If you are not connected to the drive, you can save to another drive to preserve any work in progress. >>> Tried making a copy to my local drive, opened that one, still won't save   Not enough disk space Free-up space on the drive you tried to save to, or choose another drive. Note: RSLogix 5000 cannot save a project to a drive with less than 2M of available space, regardless of how small the project file size. >>> There's way more than enough space for this file
  21. L64 - redundant processor go to DISQ I have following issue if someone can help me with:- - have Redundant PLC with L64 controller - making any bulk edit online in primary controller (say add or delete 50 rungs), secondary controller goes to “disqualification” mode. It comes up when you power recycle the secondary controller and after all program sync happens with primary controller. Alternatively, it does not happen when they are adding/deleting one or two rungs.  - Initially, it was all working fine with bulk edit too but this problem came lately.  - It looks like to me, RM module throw the sync error even before completing the transfer of data from Primary to secondary. I was thinking, if there is some configuration related to RM or CPU where fault can be delay little bit until memory sync happens. Please help if someone came across similar problem/ issue? I can provide more information if required.

  23. I am in the learning phase of HMI and PLC programing and am trying to use some of the hardware that has been donated to me. I have an AB panelview 300 micro terminal and a Micrologix 1000 Plc (they are not tethered yet). I have constructed a small test board with everything mounted to it and have successfully written and downloaded a simple project to the plc with timers, etc.   Now I need to find a way to program the terminal to make changes to the program.   I am looking for some free panelbuilder 32 or anything that will allow me to program the terminal and use it.   Can anyone help me? All help will be greatly appreciated!
  24. Hi! I just started with PLC programming. I am trying to get the time between a output signal and a input signal. The problem is that the time is ~200 ms but when i measure it with this code:   TONR(Timer1); IF PosFeedback <= PosFeedback_Min & not Timer1.Reset THEN Timer1.TimerEnable := 0; FullCloseDeltaTime[1] := Timer1.ACC; Timer1.Reset := 1; END_IF; IF (move & not Move_LastScan) THEN //Start timer Timer1.TimerEnable := 1; Timer1.Reset := 0; END_IF; Move_LastScan := move; i only get even values in intervalls of 50 ms like 150, 200 and 250 ms. I have changed the real time sample rate to 11 ms so i don't understand why i don't get a more exact result. And i can see in my trend that the time isn't exactly 150, 200 or 250 each time. I i tried and time my own click on a button and i see the problem is the timer, i only get values in an interval of 50 ms. Is there a way to make the timer more exact?
  25. I have L61 with nonvolatile memory installed. The controller will read the program from CF card on power up. The issue is that some variables are lost or not the most up to date values are read from the card since it remembers them as they were last stored on the CF card. So stuff like motor run hours, etc is not up to date. Is there any way I can update these variables or tags on the CF card as they are updated by the process? Or what would be proper way to deal with this issue?
