Hi all. I have a 1769-IT6 thermocouple/mv input module. It is connected to a micrologix 1500 unit. The green okay light illuminates on power up, but after you download the program and put it in run mode the processor faults. Terminal block with the cjc's are on the unit. The error message just says the I/O module has encountered an error. The hex code under status bit 6 is 179h. This error code is not in the manual. Has anyone else encountered this? Oh and I only have channel 0 enabled for type k thermocouple. Has anyone else had this issue, or know if it is a configuration issue. Any help would be appreciated. Thank you.

analog output card 1734-OE2V parameters, fault/actions, program mode
Jiggadoo posted a topic in Allen Bradley / Rockwell Automation
I have an analog output card 1734-OE2V and there is in the fault/actions page parameters for program mode. What is program mode and when it is activated? Fault mode is clear but... Program should be written the value, but when this happens? -
I am looking for how others have set up vertical axis motions using the Kinetix 5700 servo system. I have a 2 axis pick/place unit with a horizontal axis (X @ 2500mm) and vertical axis (Z @ 1200mm) that works as designed during normal operation. X axis has no holding brake and Z axis has a factory installed 24vdc to unlock brake. There is a GuardLogix L81ES control system that handles the safety and control. On pressing E-stop/opening Gates the vertical axis will stop the motion, apply the brake and hold with no problems. (2198-D032-ERS3 Drive, 2198-P031 Bus Power, MPL-B430P-MJ72AA X Axis, MPL-B330P-MJ74AA Z axis) The issue that I ran into was an accidental download of the program without activating the e-stop and the vertical axis dropped unexpectedly when entering program mode on the processor. I am aware that this instance was my fault as the programmer, however I am also concerned that this might occur again in the future if the controller ever enters fault mode or someone else completes a download. I have done some investigation with the "ProgrammedStopMode" parameter on this single motion axis and attempted all 5 options and the vertical axis still has a free fall drop for a second before the brake grabs hold - so evidently this is not working for me. (Page 24 of Vertical Load/Holding Brake manual - https://literature.rockwellautomatio...t003_-en-p.pdf) I am curious if there needs to be something done elsewhere as the X and Z axis are set up as coordinated axis? I also am unaware if I need to preform some action/parameter with the bus power supply for this? The current state of the machine as it sits now is preforming a MSF in manual mode after 5 seconds of inactivity or 30 seconds in auto mode. This axis is usually in demand every ~22 seconds. This will shut down the axis after preforming a brake test on the vertical load and seems to function OK, however it is still in the back of my mind the issues mentioned previously if we ever enter a controller fault while indexing. Thanks for your insight

Hello, I've got a problem with a Motion control sequence. In my code i would like to perform operation like: When package move on optice sensor position it stopping and perform MC_Move operation. It's moving for X lenght, but sometimes it stop a little bit after sensor and i would like to stop MC_Move instruction faster - directly when state on sensor goes down. Which instruction use and how to code it to make it good. I already made something like. **pseudocode** seq=1: if sensor then MC_MOVE_instruction_execute=True; seq=2 seq=2: f_trig(sensor) If MC_MOVE_instruction_done or MC_STOP_instruction_done then MC_MOVE_instruction_execute=False; seq=3 seq3: REST OF THE CODE SR_INSTRUCTION(S=F_TRIG.q, R=MC_STOP_instruction_done OR SEQ=3) MC_STOP_INSTRUCTION_EXECUTE=SR_INSTRUCTION.Q Am i doing it right or there is another way? Thanks in advance.

Hello everyone, I have a problem with packing machine. There are some issues with one of the axis, when axis actual position is near to 1800000 some error appear and operator has to turn off machine on main contactor. This axis is working in Linear mode. I think that rotary mode would be better for this axis. And here is my question. Which instructions, and what options i should change/check when i change count mode in axis's options. Can any1 point me some manuals to read or give me some advice ? Thank you in advance.

Has anyone had an issue with Siemens plc's occasionally going out of run mode? I was doing some research and found that it could be due to a bad analog input. Is there a way to tell which input or output is causing this fault? I know I can create a hardware diagnostics error organization block but that only correct from what I've read. Edit: I've added a screen shot of the diagnostics report. The fault that may be the problem is: Temporary CPU error: Serious firmware exception CPU changes to DEFECTIVE mode (system reaction) This plc / system was installed 2 year ago and we've had this problem occasionally since. I'm guessing the wrong firmware was used during the install. Will try upgrading firmware this weekend.

dwihim posted a topic in Modicon / Telemecanique / Schneider Electric
I have developed Vijeo Citect 7.5 in last 15 Days before at a Plant. During last 15 days scada went good and healthy, But suddenly its pop up window getting stuck after every 10-12hrs. So it is not possible to start/stop motor, drive. when press window button from keyboard then it becomes healthy again. I am unable to reach at any solution for this problem. Please help me. -
Hello PLC experts, I am master student currently writing thesis. For this, I have a initial task of making some changes to PLC program (Just started getting to know about PLCs- complete beginner). I have a BECKHOFF cx 9020 PLC connected to my notebook using ethernet. I am using TWINCAT 3.1 (VS) as IDE. Firstly, I cannot find my PLC IP address connected to my notebook . I added the route in the Twincat and it shows the PLC is connected. When, I am trying to run a program (activate boot project), I am unable to login to the PLC. It gives an error "login failed for application port 851". What I undertood from BECKHOFF scripts, there is something wrong with the ADS ams net ID which I am trying to figure it out. I appreciate all the help. Thank you.

Hi everyone, Now I used Micromaster 430 controlled by a PLC. I set parameters as follows: P0010: 0 P0100: 0 P0700: 2 (using BOP-2) P0701: 1 (start) P0702:12 Terminal 3+4: Connected to Analog output of the PLC Terminal 5: connected to 24V via a relay which is controlled by the PLC DIP switch1 on (analog input1 with 0-20mA) When I turn on the relay to power to terminal 5, the inverter runs about 5 seconds, then stop automatically while terminal 5 is still powered. There are no fault and no alarm. I checked the parameter P0947 and P2110 with value 0. Especially, when I set P0700 = 1 (using Start button in Panel), the inverter runs well without stop automatically. Please give me some solutions.

Hello, I'm working on a project where I'm trying to create Remote Acces to old PLC's. The Mitsubishi FX0-20MR-ES is one of those PLC's. I got the remote access working by using a Serial to Ethernet converter, but I just found out that FX0 serie can only be put in Run or Stop mode by manually flipping the RUN/STOP switch on the PLC. I was wondering if there is any software solution that enables me to "simulate" the stop function while the switch is still set on RUN. That way I can still program the PLC from a remote location. I know this is possible with some PLC's by turning off a whole registry in the software, that way the PLC thinks it is in STOP while it's actually still running. I just don't know how this would work with the FX0. I hope someone can give me the solution I'm looking for. I'm looking forward to the reactions, Jimmy

Hi All, I am doing an application that use servo motor to feed plastic film to a target length (set by operator), and it need to stop immediately if marker sensor is ON. This application is control by Omron CP1E PLC. It will feed plastic film in 500-1000mm/s depends on the target length set by operator. It is require to stop immediately if the servo feed length more than 90% of the target length and the marker sensor is ON. However, is there any possibility for the servo to stop immediately once the condition is meet? As I am using PLS2(887) to feed with target length, and INI(880) to stop immediately, however, it cannot get the desired result as servo not able to stop immediately after marker sensor is ON, I am not sure is because of the PLC scan time, or servo need time to deceleration (deceleration rate assigned to #FFFF). Appreciate anyone able to assist on this. Thank you.

Hi all. I have a question about how to set up the motor in rotary mode. My application will be a basic rotary table driven by a servo motor without gearbox between. So, in my servo drive axis settings, I select the motor as a rotary mode. then I defined the maximum position setting value for 360 degrees, and minimum to 0. So far so good. But the problem comes when I want to make an absolute move using the mc_moveAbsolute to move 360 degrees. Whit this settings the error "target position settings out of range " will come up. So, what is the solution to rotate 360 degrees without generating this error? if I set up the maximum value to 361 degrees and then if I rotate 360 the error will not occur and the motor will rotate 360 degrees as I aspected, but it's this correct ? or there is another way to do it? Thanks

Anyone knows if there is a C-mode hostlink library for NJ/NX ? Also, a C-mode hostlink library for CP1L could be helpful, to translate such a library to work with NX1P is probaly less work whan writing a new library. Maybe Omron France has developed such a library? - they seem very active.. Background: Looking into writing a programmatic c-mode hostlink master for NX1P12, this is for connecting the handheld NSH5 HMI to the NX1P12 via RS232C using a CIF01. I have the hardware set up, and an machine built, expected some compatibility efforts by Omron.... but the NSH5 seems to talk C-mode hostlink, and the CIF01 only seems to support the FINS version hostlink. On the NJ you can of course add an SCU module, thus not need a library. But working with NX1 ( due to limited space available ), you are dependet on available CIF-modules which do not support C-mode hostlink.

Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form. http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

Hi, I have some trouble with a CJ2M-CPU33. My client did a backup to memory card earlier today, and after this we did some changes through remote link. Now the client wanted to restore the previous backup to the PLC and has done so, but the system would not function correctly. After going online on the PLC it seems like the PLC is stuck in "Stop/Programming Mode". When trying to change to "Monitor" or "Run" mode a dialog comes up containing the following message: "Failed to change the operating mode. The operating mode may be still changing in the PLC." - All the dip switches are set to off after restoring backup - The PLC has been rebooted - I have downloaded the application again through CX-programmer - Verified that the PLC is set to start up in "Monitor mode" But nothing helps. The same message comes up when trying to change the operating mode. Hoping anyone can help to resolve this issue as it is very critical for us and the client. In advance, thanks for any tips or help received. Best regards Stian

I’m using a Omron NJ to manage a LinMot linear motor .. all is going very well; however, there have been a few times during this development phase when the actuator, or programming creates a fault, perhaps from a following error, or exceeding a limit. The result is sometimes scary. The actuator might accelerate into a hard stop. Not a big deal, the ends are protected with Sorbothane, so it isn’t a big problem .. yet. Once the system is correctly programmed, it shouldn’t ever accelerate an actuator into the hard stops. In spite of my newbie-ness to Omron programming I’m aware of the need to employ error & fault action that will stop a run-away actuator in closed-loop control, rather quickly. Just how to do that.. has evaded my research. I’ve noticed: “FaultHandler” in the W507 & W508 Manuals. And, been quite frustrated to not find any reference to FaultHandler or FaultHandeler() .. which kinda suggests it’s a program?… and also expected to get some clues in the "NJ Programming Best Practices V1.1” so far… no luck. Perhaps I’m going about this all wrong.. The LinMot Driver Controller might be the way to go.. An error message from the NJ to the LinMot drive would quickly shut down movement in closed loop .. instead of turning the motor into a rail gun… Any suggestions at how to do it with the NJ, would be greatly appreciated.. Thanks Regards, Michael PS: here’s the progress so far, thanks to many out there, and on this forum ... https://www.youtube.com/embed/B0UGm9JTw3U?rel=0

Hello all, Require some urgent help on a project, apologies if poor explanation.... When CS1 CPU goes into stop mode in fault condition, eg fatal cycle time error, outputs retain in the state they were when CPU was stopped. In code we monitor CPU status and turn output high to pull in relay to indicate CPU status normal to wiring circuit. But if CPU goes into stop mode relay remains energise as code is not running to turn output off?? Therfore for examples conveyors keep running... How can we prevent this, can outputs be configured to go low if cpu stops? Any other ideas? Any help will be appreciate, thanks.

Micrologix 1400 reverting to Remote Mode on its own
jspobuk posted a topic in Allen Bradley / Rockwell Automation
Hello, As the title indicates, we have a micrologix 1400 that has been installed for a long time. Recently it faulted out on 71h and was in Remote Mode. Do these PLCs revert to Remote Mode when in a fault condition? We placed it back in Run Mode and everything worked fine, but how did it get to Remote Mode in the first place? Thanks, J -
For some background information, I am in the process of converting a Mitsubishi FX2N to a Siemens S7-1200. I am viewing the Mitsubishi program with GX Developer Version 8.116W. There is this subroutine in the Mitsubishi program that appears like it will never run. I think the purpose of this subroutine is to clear the status of the devices in the PLC. I have attached a picture that demonstrates what I am dealing with. Can anyone tell if the subroutine P7 will run at any point? Thanks! For those who are not used to the Mitsubishi world or want to brush up on their Mitsubishi knowledge, below is some information regarding the devices and functions used in my example: M8000 - Always on bit (turns on when PLC is running and turns off when PLC is stopped). M500 - Just some random memory bit I chose. FEND - Indicates end of main routine program (everything below this rung is either a subroutine or interrupt routine, so it will only be processed if called from somewhere). P7 on left side of power rail - This is a label that indicates the beginning of the subroutine called P7. M8031 and M8032 - Special memory bits that, when set, tells the PLC to clear certain devices. SRET - Indicates end of subroutine.

Hi all, I have created a program using the binary counter and timer instructions and everything works fine (yay!), but I am not entirely sure if there is a major difference between using Binary mode or BCD Mode on the PLC. Does it just come down to personal preference or is there an advantage to using a particular mode over the other? Also, does the operating mode affect anything besides counter/timer? The option in CX-Programmer seems to indicate it doesn't. Cheers, Jay
