  1. "PLC No Response" NB HMI Omron

    Hello Everybody, I continued to work on project this morning but I seem to be plagued with the "PLC No Response" error. This error will only come up when I assign a PLC address to a particular object.  I have followed the steps in the post(https://forums.mrplc.com/index.php?/topic/39885-nb-designer-hmi-plc-no-response-error-solved/) to try and clear the error but am having no luck. In the screenshot I have assigned the large "Start Process" as a bit button with the write address being W50.00. When the button is pressed it should trigger a bit in the PLC but this is when the error appears. During this test I am connected to the PLC and in run mode with the PLC and HMI address assigned correctly. I have read and followed the section in the manual regarding "PLC No Response" but still no positive results.  I just want to check that there is nothing I have done at a programmer end that could cause these issues. I am happy to provide files. Thanks, Ryan

  7. Omron NB HMI Recipe Setup

    Hello Everyone. we have Omron NB7Q-TW01B. Only one HMI is programmed to run two identical machines.   Scenario: There are two different screens on HMI to set the parameters of machine-1 and machine-2. (let's say there are 10 numerical input parameters for controlling machine-1 and 10 numerical input parameters for controlling machine-2.)   Requirement: We have to design a common recipe function for both the machines. (let's say we create recipe named A,B,C,D,E,F,G,H.. of 10 parameters)   Now we need the selection to load any recipe to either machine-1 or machine-2.   Let me know if you have any idea of how to do so ?
  8. Hi community, i need help .... I want to connect my HMI GOT 1455 to a PLC OMRON CP2MC by RS-232, but i cant do it. I'm using the following connection: HMI GOT1455   -    PLC CPM2C (Interfaz CS1W-CN118)              2 (RX)          -            2 (TX)              3 (TX)          -            3 (RX)              5 (SG)         -            9 (SG)                                 -            4 (RTS)                                 -            5 (CTS) * PIN 4 (RTS) IS CONNECTED WITH PIN 5 (CTS) In the HMI I configurated driver OMRON SYSMAC, CHANNEL 2 RS-232, TRANSMISSION SPEED 19.200, DATA BIT 7, STOP BIT 2, PARITY EVEN. But with all of that I can't connect both devices. In the PLC i can see the led COMM blinking, so it should have communication, but the HMI show me "Communication error. Refer to System Alarm in Utility Menu"
  9. halo, i'm newbie in HMI and PLC. i have a problem connect HMI omron NB7W-TW00B TO PLC OMRON CP1E. i done setting same baudrate,data bit,parity check, and stop bit in HMI and PLC and i use nb designer for create a HMI display. and this is attachment: a cx programmer, bit switch and bit lamp in nb designer. and the output in hmi is [2]PLC No Response:00-00-1 can you help me? thanks
  10. Hello all, I am looking into creating a system where I have an NX102 in a main panel, and numerous satellite panels (up to 20) with EtherCat Slaves which would then have daisy-chained EtherCat slaves. Essentially, the main panel would need a GX-JC06 to allow branching out, but this only has 6 ports.  1 of them would be used to connect to the master (NX102), but would I be able to connect one GX-JC06 to another?  I highly doubt the GX-JC06 behaves like a typical router, but I can't find any documentation about creating more than 5 branches. Thanks, K
  11. I'm editing a dual language project for an NA5 HMI. It's working fine except for the message at startup. To modify the project I've had to update the firmware on the HMI. I'm using Sysmac Studio 1.15. Startup language seems to be set correctly. Any ideas?
  12. CP1E won't connect or run program

    Hi there! Today a CP1E-E10DR-D suddenly stopped working. RUN led was off and I couldn't connect to it via USB getting this error: "Selected port does not exist. Select proper port number from Change PLC dialog and press OK button", and automatic online function didn't work as well(it's not a cable/driver problem since I successfully connected to a CJ2 CPU using same cable and PC). Since I also tried to connect with the CPU outside the control cabinet with no success, I asume there is something wrong at hardware level.  My question is, have you ever faced something like this? My plan is to try to revive it somehow (maybe trying to locate any defective component in the PCBs or something). So I was just wondering if you have any advice in order to achieve it.  Thanks in advance!

  15. HMI Replacement Options

    Hello! We are looking to find a replacement for our Omron NS Screens in what seems like about 20 systems...there are so many third party/other vendor options available, I am honestly overwhelmed, so I thought maybe some of you had great experience with other vendors screens that I could look into using in our equipment.  The screen will have to communicate with an Omron CJ PLC, serial or Ethernet is fine, Ethernet is preferred.  Would also prefer screens that actually have Omron drivers.   Thank you!!
  16. Hi to everyone!   Our company is planning to build >10 same machines. Some features will be developed later down the road. And here I'm facing a problem where I need to start tracking PLC and HMI program build revisions. Has Omron any internal tools to generate program build revision? Regards, Scotty
  17. Hi all, I'm new here and need an opinion from you guys on how to set the Gateway for PLC CP2E in CX Programmer ? From my discussion with supplier (OMRON), they mentioned it was unable to set any gateway for CP2E model but I found on some sources that for previous model for CP1L is able to set the gateway. Supposed to be the Gateway function can be supported by latest model, am I right ? Need an explanation on this, Thank You
  18. I would like to get some feedback or alternate suggestions in terms of monitoring a database connection. The attachment here shows the current programming for the DB_Connect function block which requires the Execute input to constantly be ON.  From what I can tell, if the connection is dropped - let's just say the Ethernet cable is unplugged - this input will still be on, and according to the function block, still connected. The Get1minClk is in place to continuously try establish this connection once powered on, but I cannot find any way to periodically check this connection without dropping it and reestablishing it.  My understanding is the _DBC_Status.Run only checks that the PLC service is running properly, but is there a way to monitor a heartbeat of the connection TO the database?  The only way I've found thus far is to drop the connection and reconnect.  But this would be detrimental to the system as it would possibly be reconnecting to the database while trying to write to out to it and hold up the show.  As it stands in the second image, the Ethernet cable is unplugged, but the connection shows no errors. Thanks and happy Friday! -K  
  19. Hello,  I am using Omron’s safety G7SA to relay 24 volt line. But the strange thing happening is that, one relay’s output is only 5 voltage, even the relay is on. I exchanged relays, it remains the same. Maybe the base socket is problematic?  Or is this just G7SA failure? 5v (exactly 4.96v) is strange. Please give me some advice.   Many thanks in advance.   Ting    
  20. Q-Series - Operation Error 4100

    Hi guys. I found error on PLC and from PLC diagnostic I found this Operation Error 4100 as per attach picture. FYI, there is no SD card mount onto this PLC. I wonder what is ATA card. This error wont affect the operation. Any advise on what to check?   This ladder is pop up when I clicked, error jump.   Thanks.
  21. Hi, So I have a problem, that BootP DHCP server doesn't find my 1734 AENTR series B and so I can't assign IP address to it. Been trying many things. Any advice? I'm new to AB and I guess it may be a really easy thing but so far I didn't find a solution. 
  22. Hello, I am rather unexperienced with PLC's but have some experience. I Currently have 2 Lexium ILS1 motors which we want connected over RS485.  I have read a couple of manuals. I have found which format they want to receive their data and what the pinout of their pre assmbled cable is (which hasn't been delivered yet).  I am currently unsure about a couple of things. The wiring the formatting of my data i'm sending, and the program.   The pictured below show my motor (which runs when i connect it to the PC and run it using the software provided so it is in working order) and the PLC with option port (which i used to transmit data to another PLC, so again i can't blame the hardware for being at fault here). However when i connect the cable and try to communicated I Don't see the LED light up. I followed Lexiums guide on which pins to use. But i figured for good form i might include these pictures to be certain hardware is correct.      Finally here is my program. I followed Omrons quick start instructions. But: my send ready flags never become high and the way data has to be formatted for these lexiums seems very labour intensive. But this is how i understood it needed to be done. Am i doing something (or a lot) wrong here?      I hope someone can help me out here! If any further information is needed i'll do my best to provide it.   Kind regards.

  25. Hi, I have a CP1L and CP1E Omron PLC, and I try to make communication between my PLCs and my system (raspberry pi with Linux OS) using Node-red and specifically using the OMRON-FINS node ( https://flows.nodered.org/node/node-red-contrib-omron-fins) and more detail ( https://github.com/ptrks/node-omron-fins ). So I’m looking for a module to create an Ethernet port for my PLCs. ( both PLCs have RS232 port) . Can you please guide me to find a compatible RS232 to Ethernet module for my PLCs?  Thank you
