  1. CC-Link IE Protocols

    Hello, There seem to be a lot of different CC-Link IE protocols: CC-Link IE Field Basic CC-Link IE Field CC-Link IE Field Motion CC-Link IE Field Safety CC-Link IE Control CC-Link IE TSN This causes me some confusion. Are there as many variations of Ethernet/IP and PROFINET? Can you point me to a good comparison of the different CC-Link IE protocols? My understanding is that: CC-Link IE Field Basic: 100 Mb/s Non-deterministic? Good for non-time-critical communications (e.g., setting a drive speed) Implemented in software Traffic can co-exist with other TCP/IP traffic Max 64 stations Addressed by IP address Star topology I believe the other protocols are all 1 Gb/s, are deterministic, are addressed by station number, are implemented in hardware and each needs its own isolated network. CC-Link IE Control is used for communications between PLCs and robots. CC-Link IE Field is used for remote I/O and CC-Link IE TSN is used for even faster remote I/O communications. Please let me know if any of this is inaccurate. Thanks,
  2. Hello. I'm using OMRON NB Display Did someone already made time adjustment from NB to OMRON PLC? What I'm trying to do is to adjust time  from HMI to PLC. Since now I have done time sync from PLC to HMI using timer and data transfer. Now I would like to adjust current time in PLC using NB HMI. I know how to do it, but I'm some kind a lazy person. In our country there is a saying: " Don't reinvent things that already exists" Thanks.   BR, Andrej.
  3. Hello, I currently have a PLC in a machine that is a CP1H. A newly developed machine uses a CP2E PLC. The newly developed machine is supposed to communicate with the CP1H where the CP2E is a slave. I am not able to find much documentation on this specific set-up. I was wondering how to set this up. As the shared words of each PLC are on different adresses. I can't really find any documentation or any examples on how to do this. Can somebody help me with where to start with this?   kind regards, Ralf
  4. Real world simulator

    When we simulate a plc program we have to manually input the changes in input(like magnetic reed switch) For example when a cylinder goes from up to down reed turn OFF and reed down turns ON Is there any program available where we can define such things that will turn on and off during the process automatically.
  5. Hello friends I have worked with other series of omron plc but this is the first time I am working with cqm1h cpu51 series. In a factory, 4 of these PLCs exchange data with each other with a clk21 card. After a problem with one of the CPUs and replacement, I was never able to download the datalink settings. I did all the steps in the manuals step by step but I did not succeed. In cx-net software, after selecting online, I selected the data link menu, but as you can see in the attached image, the setup button is never activated. Thanks for guiding me
  6. NE1A-SCUP02-EIP

    Does anyone have experience with the NE1A-SCUP02-EIP safety PLC? We had a machine shutdown yesterday with a L9n4 error on the NE1A unit. The manual says this is a tag data link error. Does this cause the safety PLC itself to shutdown? I always thought the EIP portion of the safety PLC was only used for status reporting to the PLC. The safety portion is strictly on DeviceNet and is independent of the EIP network.  The CJ2 PLC's error log tells me it had problems communicating with the safety PLC, the VFD, and NX I/O's which were all in the same panel going through an Ethernet switch. 
  7. can i cc link  Fx3U-64CCL  with FX2-32CCL without any problem
  8. Hey guys,   I know this is a topic that has been discussed before, but I am having trouble finding exactly what I am looking for.. I want to know the most efficient way to record data from my PLC to an Excel file on my PC. I want this to be done without the use of the PLC's webserver.  Specifically I am trying to record vfd speed every 10seconds with a time and date stamp. How can I do this?   Thanks, James  
  9. Hi All, I just take over a project which involve accurate positioning and movement up to 0.010mm(around 10 microns) of a servo motor. I found out that my motor always move to an incorrect position. Let's say I want it to move to absolute position of 5.210mm, I found out that it may move more till 5.235 or move less 5.190(something like that). So i start to check if I'm outputting correct pulse. Using CX-Drive, I connect to the driver then i found out that the pulse is correct and consistent(for example i use my pulse per revolution and pitch to determine how many pulses) Currently I'm using an incremental encoder and servo motor and my PLC cycle time is around 12 ms and my servo move at a speed of 0.66mm/s. So I was wondering if my PLC scan time will affect my accuracy in moving ?? I'm using a CJ2M PLC with CJ1W-NC413 pulse card , incremental encoder and a servo motor. I want to make sure is not software limitation or anything wrong on software side before I bring it to my mechanical team   Appreciate all inputs here and thanks!
  10. Good Afternoon, I am wanting to do two things with and ORMON PLC and HMI with CX-Programmer and NB-Designer. 1. I want to display the current time from PLC on HMI with the real time clock. 2. I want to be able to enter a time on the HMI which will be compared to the PLC time and will stop a process when when the entered time is equal to the actual PLC time.  If I can have some help with this that would be a great help. Thanks,
  11. How to scan Ethernet/IP network?

    Scenario: You show up on site and the only knowns are Omron PLC and EtherNet/IP network. You have a laptop loaded with CX-One, an ethernet cable, and the ethernet port that is connected to a known EtherNet/IP Omron network (you can not see the PLC). I have previously worked with Siemens systems and used Primary Setup Tool and Proneta with wonderful results. Do similar tools exist for an Omron environment?  Question: How to (relatively quickly) scan an EtherNet/IP network for connected devices without knowing their ip addresses?  
  12. So I have a plc program where most of the outputs are based on a counter that goes from 0 to 1000. The counter speed is adjustable and is generally set to run through a full cycle (count from 0 to 1000) anywhere between 0.5 to 2 seconds. The problem is, when I try to energize an output by using an EQU instruction, it will almost always skip the count because the scan time is not fast enough. I've been using a LIM instruction which has been working, but its not quite as accurate as it needs to be. I switched the counter logic to be continuous to try to make it faster which made it almost perfectly accurate... But only in the continuous task; it made the other periodic task significantly less accurate. I was curious if any of you had any tips on how to remedy this or just general help. I am still relatively new to PLCs and ladder logic so any advice would be awesome, Thanks in advance! Edit: The purpose of the counter is to cycle through from 0 to 1000 over and over again. My outputs actuate during a certain interval within this cycle (For example I would say actuate from 300 to 800 and it would stop and end once it hit those values via an EQU or LIM instruction). I wrote the logic as follows: First I calculate how many cycles per minute I want to perform, using that value I calculate how many times I want to increment my counter per millisecond. Then a timer is given a preset of the total cycle time. While that timer is running I continuously multiply the timer's accumulated value by the "cycle count per millisecond" that I calculated earlier; the resulting value is the current count that all my outputs are based on... Hopefully that makes sense, I know it's not the best but I could not figure out a better way of doing it and I know rounding is certainly making the accuracy worse. My hardware is: Allen Bradely PLC (5069 l306erms2), 5069-ob16, 5069-ib16, and a Kinetix 5500s2 Driver for my motor(s)

  17. I am new to PLC programing, I want to connect FX5U and MR-JE-_C via CC-link. When I connect FX5U and MR-JE-_C directly everything works, but when I connect them in HUB (I need to use HUB because later I want to connect GOT2000) I am getting error 86.1(network communication error) on amplifier. Previously I set up IPs shown on pictures below, now sometimes works, sometime doesn't work and sometimes works for 30 seconds and I get same error. Did I miss something? I don't know what to try else.  
  18. Omron NJ501 - IFM IO-Link - Wenglor U1KT001

    Hi, I am looking at reading an ultrasonic sensor value through IO-Link, using a Omron NJ501-1320 PLC connected through EtherCat to a IFM AL1332 master with a Wenglor U1KT001 Ultrasonic sensor. I have managed to read the 2 outputs of the sensor using this: Output_1 := TestABit(USINT_TO_BYTE(TxPDO_input_byte_1_6000_02),USINT#0); Output_2 := TestABit(USINT_TO_BYTE(TxPDO_input_byte_1_6000_02),USINT#1); But cannot read the ultrasonic sensor distance value, this is what page 2 in the manual says: Measured Value in 1/10 mm 2…15 14 Bit 300…4500 Octet 1 Subindex 3 (LSB) 2 1 Bit Offset 7 6 5 4 3 2 1 0 I tried a couple of conversions but couldn`t get the distance reading. Any ideas? Help appreciated.
  19. Hello everyone! I've installed GX works 3 according to the instructions in "https://plc4me.com/gx-works3-v1-308q-mitsubishi-full-real-100/". I don't get any errors, I can run the PLC and simulate completely OK. In the communication test, when the configuration is missing some components in the module list: Input, output, I / O module,... (https://ibb.co/ZVMcmQn) I hope you can answer for me?
  20. The only thing I can find in help re using the buzzer is to use a multi function button. I want to use the buzzer as an alarm buzzer and turn on $SB13 or $SB14 from a bit in the PLC. Can anyone help please?
  21. I'm working to fix/improve the functioning of a program running on an a PLC5/40E.  I think high Scan Times are a big problem with this current program.  ((Backstory:  someone added some quasi motion control, and it sort of worked for a while.  Now that it's broken, the operators of this machine want it back. ))  I'll keep my question simple, PLC5's are new to me: There are 36 rungs with CPT instructions as the sole output, a third of these instruction are executed every scan.  I'm going to replace them with MOV instructions. My question is, is there any sneaky PLC5 reason to do a CPT instead of a MOV?  Is there a better way to do this? The CPT instructions that execute move integer values to a data file used by the HMI to control the coloration of touchscreen buttons.   Thank you for your time. PS: I'm new-ish to this forum, please feel free to let me know if my question was asked correctly or not.
  22. Hello everyone, As the title suggests I am trying to display on a GOT1000 the real time frequency that the inverter is running at. I have attached my CC-Link settings and the associated programming as well. I tried using the example program from Mitsubishi but I got lost. From my understanding I should be seeing the output frequency in W3C4 however, I am not receiving any data. Any help would be appreciated. 
  23. HMI on CC LINK IE FIELD

    Hello all, kinda lazy question, but I'll rather ask, before I'll went to deep into HMI scripting. Because of a design of CC link, there are RWr and RWw Is there any simpler solution for displaying value stored in PLC, while also letting HMI operator change the value and save it to PLC, than scriting in HMI? hope it makes sense to you thank you in advance
  24. The CC-Link system on a machine has been intermittently dropping out.  Normally the Link Scan Time runs at a solid 87ms.  When the system "drops out", the link scan time will increase.  Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network.  The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane.  Is it possible for one station or one of the cables to create a network wide problem?  Any ideas thrown at us would be appreciated. 
  25. I am trying to display the time from an Accumulation timer. Using a data display object I am able to see the time in the following format 00:00:00.0000000. Is there a way to format the time without the decimal seconds I just want to see 00:00:00 (hours:minutes:seconds)
