  1. Hi All, I need to start PLC Data Logging using an SD card in the CPU module for an iQ-R PLC.  I have not attempted this kind of logging before and I was wondering about any restrictions on the type of SD cards that can be used. The documentation I have found says "SD/SDHC memory card: 32Gb maximum". Does anyone know why can't I use a 64 GB SD card ? (maybe due to addressing limitations?) Also, when I look for SD cards, I see different speeds of data transfer such as 120 MB/s or 100 MB/s and I was wondering if there is any difference as far as the logging is concerned.  Does anyone know if there are any other restrictions, brands that don't work? Useful tips? Cheers    

  2. Detect CF memory card activity

    VAU_RMA posted a topic in Omron

    Hi! I'm looking for a way to detect if/when a backup has been made to the CF memory card and a way to detect if a backup has been written from the CF memory card to the PLC memory. A counter, a time/date, etc? In short: detect backup and/or restore Application: Trigger an audit log event on a seperate system Any known solutions?
  3. My Powerflex 525 VFD “Output Frequency” starts to drop out (20, 19, 18, 17, 16, 15, 14, 14, 0, 13, 0, 12, 11, 10, 0, 9, etc.) when the Command Frequency approaches and falls below approx. 14HZ. The “Command Frequency” however does hold steady and does not drop out (20, 19, 18, 17, 16, 15 14, 13, 12, 11, 10, 9, etc.). The Pulse In Scale is set to 64. I'm using the Pulse Train Input, and as a test started the frequency of the Pulse Train Input at a frequency such that the Command Frequency started at 20HZ, and then slowly adjusted the frequency of the Pulse Train Input down such that the Command Frequency decreased down towards 0Hz. I did notice that this apparent drop out point is exactly one tenth of the Max Hz value. So for example, with Max Hz set to 140, the dropout starts to occur at approx. 14 (140 x 0.1 = 14). This apparent one tenth drop out point held true for other Max Hz values we tried, including: Max Hz set at 60 started dropping out at 6 Max Hz set at 100 started dropping out at 10 Max Hz set at 140 started dropping out at 14 Max Hz set at 180 started dropping out at 18 Max Hz set at 190 started dropping out at 19 Max Hz set at 200 started dropping out at 20 Max Hz set at 250 started dropping out at 25 Max Hz set at 400 started dropping out at 40
  4. Hi, New to the forum and pretty new to PLC programming. I took the 3-day Sysmac training a couple months ago, but just recently set up one of the NX1P2 units that we'll eventually use for a robotics application. Right now I've got it set up just to experiment with, so I have 3 physical switches (1 momentary, the other 2 toggle) and 4 indicator lights hooked up. Ladder program is set up to light up different LED's when the momentary contact switch  I_SW1  is pressed, based on the position of the other 2 switches. Here's the issue:  When both of the toggle switches are ON (see lines 4 thru 8), all of the LED's light up as expected as soon as the momentary switch I_SW1 is pressed. However, if either or both of the toggle switches are OFF (see lines 0 thru 3), even though it seems like the logic is correct, nothing happens on the output. Lines 0&1 were modified as shown to see if using the variable O_Light1 instead of going directly to O_L1 output would work, but it didn't make any difference.   See attached images for example of working and not working ladder sections as the momentary switch is pressed. In the "working" image, both the toggle switches are on. In the "not working" image, both toggle switches are off. PLC's input & output indicator lights match what Sysmac is showing in the monitor screen, so I'm pretty sure it's in the ladder logic and not the physical wiring.   Thanks for any advice.

  5. Troubleshooting NS8 Hmi

    Choi07 posted a topic in CX-Designer

    Good day sirs, i would like to see your help with this our company owns multiple HMI Omron NS8 it seems that this unit always break in the site. we fixed one of the unit but it is only showing white screen is this possible that there no CF connected inside the HMI? ( note i was newly hired by the company wanting to help my superiors) thank you in advance everyone

  6. Origin search - different position

    pszczepan posted a topic in Omron

    Hi I have servo motor controlled by smartstep 2 and controlled by PLC with pulse output. Origin search I have set as below Sometimes I have problem with correct home position. Normally when original Input signals become ON drive slows and after 1 cm I have home position due to slowning ramp, but somtimes drive stops immediately on the edge of original input sensor. I have no idea why it is like that. Maybe you can advise sth or get some clue thanks in advance for any help

  7. FR-A740

    ABlearner posted a topic in Mitsubishi

    Hi One of my friend want use more analog output on his vfd. Its a Mitsubishi FR-A740 type. Currently the AM signal is for current, but he needs the speed and frequency too.  As we saw its only one analog output is avaiable, but you guys might know better. Can someone confims our theory.   Thank you.
  8. Hello, I am trying to flash an indicator light (Banner  K70LBGYRPQ ) every .5 seconds.  The PLC manual says 2.5A per channel.  The light uses roughly 113mA max current @ 24vdc.  I am using output 0 to do this (O:0/0).  I think I may have ruined the output by flashing the indicator light.  Has anyone ever experienced this before?  Is there a minimum pulse time for this PLC?  What do people normally do when wanting to flash an indicator light such as this?  This is not the first time I have seen this happen.   Thanks in advance!

  10. Output polarity selection

    franciscoazzad posted a topic in Other PLCs

    Hello to everyone. Nice to meet you all. How are you? I hope you are doing well. I’m developing a program with the purpose of make something similar to a pulse train in the output. However, sometimes I need the output to be a “positive” pulse and sometimes a “negative” one. By positive and negative I mean the polarity in relation to the pulse train source. I’m trying to use a pair of bits in order to switch between the two choices of polarities. I attach a simplified version of the ladder diagram I’ve made. When I thought about the logic, it seemed logical to me, however, it isn’t working as supposed. SM0.4 is a pulse train source. According to the software manual, it is a pulse train with 50% duty cycle and a cycle time of 2 s. That it to say it says at TRUE for one second and return to FALSE for another second. I assign the value of that variable bit to the M0.0 memory bit. I get the negative version of the pulse train logically negating it in the Network #2.                 I assign the value of two inputs, I0.0 and I0.1, to other two memory bits, M0.1 and M0.2. ·         When both inputs are in a FALSE state, the output stays FALSE, disregarding the state of SM0.4. (Case #1) ·         When I0.0 is TRUE, M0.1 is TRUE. However, Q0.0 stays at FALSE no matter SM0.4 is TRUE or FALSE. I attach a pair of pictures. (Case #2) ·         On the other side, when I0.1 is TRUE, M0.2 is TRUE. In this case, the output shows the correct behavior. It is the negated version of the pulse train source. (Case #3)                 Has any of you experienced something similar? Is there a better way to execute my purpose?                 I’m not executing the program, just simulating it with KincoBuilder from Kinco. However, it has always worked fine for me. Thanks for you attention. I look forward for your responses. Kind regards!
  11. I have a piece of machinery that has multiple PNOZ m1p units that communicate to each other.  My trouble is that the base units versions vary from 5.6 to 6.5 and we found a programmed SD in the older base versions will not run properly in the later base units. We don't have the software and frankly, taking on the liability of the machines safety if we reimage the chip to newer software (which we also don't have) is not in our best interest.  The company that created the system may not service the system anymore thus rendering the 3/4 million dollar machine down to scrap metal. Anyone know where I can get a base version list which os sd cards are compatible (ex..but not exact...for reference only...V5.6 to V6.2 will work, but upgrade required at V6.5 base)?   From this we can add up the upgrades and propose full replacements. It was a great idea, but can be crippling with the way technology changes. Thanks, Mike    
  12. Hi, Currently Im working on R08CPU using GX Works3 1.066U and I installed a 16GB SD memory card. Where can I find the tool to format the SD card in GX Works3 ?   
  13. Hello guys, how many (maximum) analog inputs/outputs can CPU 1215C can reach without any issue?   I try to search in google but can't find convincing answer.  Thanks for your help.
  14. Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems.   Best Regards, BR  
  15. I am having some trouble at a customer's site getting a program transferred from an SD Card to update the HMI program in an NA Screen.  I am not there but when the customer tried to transfer the new code they got a message "OS Version Mismatch - Install OS 7.4.0 the user program expects." I am not sure what to advise them because I can't find this when I search the NA manuals. Any help would be greatly appreciated, I am in NY and they are in China so I can not even reach out to Omron Tech Support right now because they are closed. I attached a screen shot of the HMI.   Thank you!!!

  16. A1S68AD CARD

    vipin posted a topic in Mitsubishi

    Hello. I have a system in which an A1S68AD card is used, that card has been damaged . I replace that damaged card with the new A1S68AD card with same wiring and same setting of dip switch. But at channel number 3 there is a RTD connected which gives 4-20 mA signal. But in Plc at channel number 3 the data register is showing -2400 fixed value all the time and in actual the temperature is varying. But PLC SHOWS FIXED VALUE OF -2400. PLEASE HELP ME OUT.
  17. 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?
  18. I have an analog output card 1734-OE2V. As a default, there is selected fault mode as 'Go to Low Clamp'. I am using output range -10V to 10V. What is the value for Low Clamp. Is it 0V or -10V? If I want it to be 0, do I need to select 'use fault value' and set the fault value to '0'.

  23. Evening, I struggle with simple task... I need to activate PLC Output at the specific time of a day. I`m using GSV to obtain PLC time, data is being moved to DIN[7] registers. Then I have three EQU (Hour / Minute / Second) and at the end of rung there is OTL for output. Rung below I have two EQU (Hour / Minute) to disable output at different time - OTU. However every time OTL is energised , OTU on rung below is fired too. What am I doing wrong here ?
  24. Hello, I need to control a stepper motor(have stepper driver) using NX-PG0232-5 with NJ301 PLC. The function is simple, i need to run the stepper motor continuously at a specified velocity. So, in NX-PG module I've made the settings (Ch1 output mode as "Velocity continuous pulse output") and given the tags to IO (as shown below, sorry i'm not able to attach image). I've also added the initialization program to switch on the vfd.
