  1. PLC occasionally going out of Run mode?

    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.   
  2. Hi everyone, Using Cicode programming ... I'm try to make a function empressed Button's input command that still running forever until the user press the Button again .. so if i press the Button at first the function inside Button will be running , But i wonder to terminate that function by press same button second time or don't mind if you suppose other Button for stop running the function ... plz help to make a code or something else to stop running of my function.

  4. Hi guys. I have a new SRM50-HAV0-K01 sick encoder for my ELAU servo motor (model: ELAU sm 070-60-010-P0-45-M1-B0), and need to program it according to an old one (which seemingly is broken) via hiperface. device: PGT-11-S LAN software: SOPAS 2018.3 build 4.1.1.324 (Vm version 1.8.0_73) I tried to find any certain way for programming of sick encoders on the net using the mentioned device and software, but cant. all is only about datasheet or how to use teh software without an specific instruction. I am not even sure of that the old one is broken, except that in the analysis mode of the SOPAS (entering via hiperface) I can see the the  sin-cosin graph out of its limitation line. The thing is I have bought a special tool which has not any specific instruction and SICK group does not reply any exact instruction for my issue. Here is my questions:   How can I program the new encoder just according the old one?   And how can I assure that the new one programmed just as the old one?    and what is the definite sign of a broken encoder?   anyone experienced?
  5. BECKHOFF CX-9020

    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.
  6. Direct Logic 05 Ethernet

    I have a control that I want to use a Direct logic 05 plc in.  It is a really simple program but it is going into a plant that has a main control panel that runs the plant.  I dont know the brand of the plc in the main control.  They want to be able to send me a command from their plc to the direct logic to turn on my unit.  I suppose that would mean a simple set instruction to my plc.  I also have a couple alarm conditions that I want to send them.  For example if water pressure is to low I would put my unit in the alarm mode and send them a low water signal.  If the chemical is low likewise,   I dont have a clue how to do this in my program.  Can anyone give me some examples in direct logic plc program for making this happen??? Thank you Thank you Thank you. MikeC
  7. Codesys

    Hello - I stumbled across some mention of Codesys and was curious if anyone here uses it. Pros/cons? prefer it over other programming software. Have it downloading currently (since you can download a free variation of the application) but it looks quite interesting. Also - what PLC hardware is programmed with it? Did not see that mentioned on their website when I was browsing through.
  8. Help needed with MM430

    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.

  10. Remote Run/stop on FX0

    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
  11. I am new to Automation Direct software and how the programs are written. Can anyone explain how they handle the analog outputs? My processor does not support the IBox that makes life easier, so I am having to do it the old hard way. I understand most of the logic of how its done for sending data to one channel but I don't understand how the channel selecting works. Can someone give me a programming example or explain how that works? I am looking at the online manual that Automation Direct provides for you for the analog module but I am having a difficult time trying to wrap my brain around how they do their analog stuff ><

  13. 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.
  14. 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. 
  15.  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  
  16. C-mode hostlink library for NJ/NX1P or CP1L

    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.

  19. 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.

  20. 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

  23. PLC Training

    Hi Everyone We are setting up a initial training in PLC programming for technicians, I got some experience with SIEMENS S7 but this seems to be an expensive choice, we would like to opt for a budget PLC but at the same time would like a user friendly software for teaching......I would like to have views of users of other PLC brands such as OMRON, MITSUBISHI or even Schneider??? thanks Jay
  24. Micrologix 1400 Float TAG

    Hello,  I have a micrologix 1400 plc connected to a length measurement gauge. The gauge sends an analog value to the plc to an analog input. I convert the value into a dimension and send it to F8:0. but I need this value in three different steps in the program. Since i just have one element of float (F8:0) is there anyway i can store the value in a different location or create more floating point tags eg. F8:1. F8:2 ?    Thank You   
  25. 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
