  1. I have a c-more HMI and an Allen-Bradley 1200, is it possible to set them up with two AB 1764-NET-IAC+ to have my computer monitoring the PLC at the same time, I have established communication from my computer to the PLC through the IAC, but I haven’t been able to integrate the HMI, is it even possible?. This is been setup for training purposes, any help would be appreciated.
  2. Good afternoon fellow members,I once again ask for your help to know if any of you have struggled with similar issues. For the past year and a half, Every 1-2 months we seem to be losing communication with one of our PLC's/racks. We have in the rack a 1756-EN2T card (revision 3.006) that will flash as if it is communicating and status OK (green LED), yet we will be unable to ping it and our operator interfaces go into error. We could also not open the web browser page of the EN2T card, nor connect to the PLC/rack through RSLogix5000. As this happened over the weekend, the local electrician was called and he tried cycling power to the rack and there was no change after it came back on (not sure how long he left power off to the rack though). The problem seemed to be fixed after we told him to pull the EN2T card out of its slot and then re-insert it.We verified the CIP cinnections for this card and it is around 98 to 101 CIP connections out of a max of 248, so not too high. the card's CPU usage is 24-29%, so no indication of problems there. EN2T Card is set to auto-negociate, just like all the other cards we use at all of our plants. Has anyone ever experienced a similar problem?Thank you in advance for all your help and knowledge-sharing!

  3. i need help

    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.
  4. 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    
  5. 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.
  6. 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.
  7. 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.
  8. 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 ?.
  9. 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?

  11. 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!
  12. 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??
  13. 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 ?
  14. 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 .

  19. 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.

  22. 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
  23. 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.
  24. I need help in identifying the fault with a 1746-NR4 RTD / resistance module. The hardware is a SLC500 1746-NR4 module inserted into slot 3 of a 10 way rack, the processer is a SLC500 5/04   I have been using the RTD module to sample the temperature of a beer-brewing kettle and a fermentation enclosure, tone of the RTD’s was used to control the cooler, the second RTD was scaled through logic and controlled a temperature element through PID logic, this has been running fine for some time. Recently I returned from work and found that the CPU had faulted, the error was on slot 3 (RTD module), unfortunately I didn’t write down the error code, but I’m sure it was xx61, I know now I should have paid more attention to this code. When I cleared the error the processer ran perfectly with no new errors, what wasn’t right was that the heater in the fermentation enclosure was switched on due to low internal temp, when I checked the temperature readings of the RTD against a fixed gauge, the RTD’s value read 10 Deg C and the gauge read 20 Deg C.   I have scaled the RTD value directly, example I:3.0 on the first line of  SCP block and I can see the temp values on this line, I believe this to be an accurate reading. I have entered the correct configuration data in the channel configuration word, i.e. the correct bit settings, I have also tried to change these, example the data format values, the RTD input type, etc.   Convinced that the module was damaged I replaced it with a spare that I had and inserted that, this has now become corrupted or damaged too, and on this one I have lost 3 channels? Example; When an RTD element is connected to the module on channel 2, 3 or 4 the green light blinks, but when viewed in RSLogix the channels indicates that there is a device connected? When testing the range of the RTD in an ice bath the zero went to -4 Deg and in boiling water only reached 66 Deg c?   I have tested both of these modules on a different PLC rack, by swapping them out with a RTD module that I know is working ok. The same fault appears with the RTD modules in either rack and with two different CPU’s. I would like to be able to confirm that the rack or pane or rack isn’t faulty. At present there is only a D/O and D/I card in the rack.   Could this is a case that the modules require re-calibration? And is this an easy fix, can these modules be reset to the factory original spec? Do they require the firmware to be updated?   I would be grateful for any assistance that could be given as I am at a loss and I think I have exhausted all avenues
