  1. 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
  2. hmi for CP1L

    how to sett up cx programer settings to use hmi/nb5q-tw00b with a CP1L-L14DR-A? and what address do i use for I/O on the hmi?
  3. hello, Somebody have suggest how need read data from slave using modbus RTU. I am using M241 PLC and read_var function. The picture you can see my PLC program. The data of slave is placed 3394 address. Then I try to read, always "READ_VAR" function get "CommError" which number is 254 that means "The detected operation error contains protocol- specific code"  and "OpenError" which number is 3 that means I don't know. How need read from slave data, which modbuss adress is 3394?
  4. Hello! I am working on a quote for a new project that will use EtherCAT but also requires DeviceNet for some legacy components.  Has anyone successfully used the Beckhoff EtherCAT coupler (EK1100) with the DeviceNet Master Terminal (EL6752) and an Omron PLC as the EtherCAT master? My concern is that the coupler will only communicate with the Beckhoff EtherCAT master, but since it is so much more expensive to get the new Omron parts to communicate DeviceNET i am hoping this could be an option.  The equipment is extremely simple and price is a major consideration.   Thank you!!!
  5. CP2E Modbus RTU Slave

    Hi, I would like to know CP2E have any modbus rtu slave function block. CP2E with add on CP1W-CIF12
  6. Hello everyone I'm new to omron plc . I have a system which consists  1. Omron Plc CP2E 2. Two stepper motors and their drivers.  3. 4 Inputs-  one stepper start push button, second stepper go back push button, third stepper 1 home sensor, fourth stepper 2 home sensor 4. 4 Outputs- stepper 1 step(-) Q 100.00, stepper 1 dir(-) Q100. 02, stepper 2 step(-) Q100. 01, stepper 2 dir(-) Q100. 03 Seuence is like that:- Initially both stepper motors are at their home sensor.  When start push button is pressed both stepper move 110 mm distance and then stop.  Now when go back push button is pressed both stepper motors should go back to their home sensors and should stop at reaching their hone sensors.  This is the sequence. Can someone please send me the program by writing in cx - programmer or upload the photos of ladder program and settings also. Please
  7. I recently wrote a simple java driver to communicate with Omron devices (CJ1 and CJ2) via the FINS protocol over UDP. I've installed this software at a number of my client's sites and it works well most of the time. However, I've encountered a number of instances where a CJ1 device will consistently return what looks like a valid response but every memory register I request will return zero. I've deployed the software to 5 sites with identical configurations. The sites have one CJ2 device and one CJ1 device.  The CJ2 devices work exactly as expected. Three of the CJ1 devices work exactly as expected but the other two have this issue where every value is zero all of the time.  This issue is not intermittent at those sites - I have never had it return anything other than a zero for any memory register for a CJ1 device at those two sites. Example: TX: [80, 00, 02, 00, 0a, 00, 00, c9, 00, ff, 01, 01, 98, 00, 00, 00, 00, 64] RX: [c0, 00, 02, 00, c9, 00, 00, 0a, 00, ff, 01, 01, 21, 08, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00]  
  8. Hello All, I'm a newbie to Omron programing  I have a program where I want to control a stepper motor with 1 plc output "pulse output0"  in my program I used PLS2 instruction but when I execute the instruction the motor won't rotate and the plc outputs are off, My wiring is fine, and my plc is CP1E-N40S1DR-A MY 1st output is pulse output 0 Q100.0 and also the driver wiring with the stepper motor is good ( I did a test with siemens plc the motor does work fine ) , what could be the problem? thanks, PLC OUPUT 0 SETTING
  9. Hi, I have a project including 32 digital outputs, 8 Pt100 probes, 4 thermocouples, and 4 analog inputs so I have to choose an OMRON PLC. The supplier in my country has only CP2E and CP1E PLCs. Is there a way to connect more than three expansion modules to the PLC? On the website is stated that the maximum number of expansion units is 3, if the answer is no, is there a solution to this problem? Thank you
  10. I'm working on a program where I manipulate REAL numbers in Sysmac studio using an NX1029020 PLC. My problem is I am new to automation and I don´t know how to display those numbers when connecting to an NB HMI. I´m trying to send the data to a bar picture and a number display. My question is which AT Specification Attribute should I assign to my variables in Sysmac Studio and their corresponding Area in NB-Designer? I tried using the DM area but it didn't show numbers on the displays, only shows *****. Should I convert my real variables in Sysmac first? Or how can I keep decimal numbers and then display them? My current configuration in Sysmac: Name Data type AT Network publish ST1 REAL %D5 Publish Only ST2 REAL %D3 Publish Only My current configuration in NB-Designer Bar Picture Addr. Type D Address 3 Code type BIN Number Display Addr. Type D Address 3 Code type BIN Data type Float Integer 4 Decimal 2
  11. Here is a post that we recently completed on the Automation Direct USB to RS485 Adapter.  The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular connector. This will accept RJ12 and RJ45 plugs.  The USB-485M supports multiple baud rates and is USB V2.0 Compliant. Read the rest of the post...

  12. Hi, I have a problem with Omron PLC and Beckhoff IO. The IO just disconnects in a few minutes and comes back! I received different errors: Link off error, Illegal slave disconnection, process data reception timeout. When I also check "Display Diagnosis/Statistics information" I see errors on all ports A and B of all nodes.  I have called and talked to both Beckhoff and Omron.  I have two NX1 and one NJ101 to test. And I have three EP2318-0001. I have the same problem with all the PLCs and EP boxes. It does not matter if I have one, two, or three nodes. I have tried different revisions of the EP2xxx from the XML file, different settings for the slave, different task periods, and the error still is persisting.
  13. Im trying to integrate the Omron Nx-ID3444 terminal with the TwinCAT software via EtherCAT, connecting the teminal to a ECC-202 coupler and it to a PC runing TwinCAT, the problems come when using the terminal timestamp whrn the digital input change. The bit input change is detected perfectly but the timestamp corresponding to said bit is always 0, I've been talking to Beckhoff and they tell me that the descriptors on their web might not be in the last version, have you experienced anything similar? I link the files for you to compare https://assets.omron.eu/downloads/ddf/en/v6/omron_nx-ecc20x_ethercat_esi_file_en.zip
  14. This is a machine with a CQM1 PLC and a NT31C HMI. Battery of the HMI run out and the HMI program was lost. I got the PLC program and identified some of the memory locations, can use the machine but not fully. Omron is not my thing so I am looking for some help to identify program functionality. some sequencer functionality and a servo, not many I/O's. The entry from the HMI is converted and has some math maybe to address the 16bit limitation, not sure. Is a home made machine and the original controls contractor cannot be located.
  15. MX2 Modbus doubt

    Hi there! I'm programming a CP1L-E CPU to control 3 3G3MX2 inverters via Modbus. It got some things right, like the INV002_Refresh_X31 block and its parameters. The thing is, I also want to read some parameters from the inverter using the INV206_ReadParameter block. My doubt is, do I need to be careful so both blocks don't execute at the same time and use the serial port at the same time? Is it better to use one INV206_ReadParameter block for each parameter I want to read? Thanks in advance!
  16. Omron 1S Servo

    Hello:           Does anyone know the details explanation of the Homing Settings for the Axis? Set the homing operation. 0: Proximity reverse turn/home proximity input OFF 1: Proximity reverse turn/home proximity input ON 4: Home proximity input OFF 5: Home proximity input ON 8: Limit input OFF 9: Proximity reverse turn/home input mask distance 11: Limit inputs only 12: Proximity reverse turn/holding time 13: No home proximity input/holding home input   Limit Input referring to Input (I/O) ? How about Proximity Input ? It is confusing with the terms. The manual has no explanation for each of the above selection.   Any one?   Simon
  17. mx2 control with modbus

    Hi all im back to trying to get my inverter to work but this time with modbus, from this post http://forums.mrplc.com/index.php?/topic/38445-controlling-mx2-inverter-without-modbus/ and im stumped, im sure its just one thing somewhere messing it up i have a cp1l-el20 with a cp1w-cif11 and a 3g3mx2 inverter and am attempting to control it via modbus, it is wired up as follows, sp+ to RDB+, sn- to RDA-, common to the plc pin and plc output pin 100.00 to logic input 1. im using 100.00 to put it into run mode the paremeters ive put in are a1=3,a2=1, a4=50, c070=3, c071=5,c072=1, c074=00, c075=1, b27=1. im using MOV to set my speed to d1001 attached is my inv002_refresh x31 fb thanks to any1 who can see my silly mistake    
  18. Hi. I use the email block on few of our NJ101-9020 controllers to send out daily reports or any status updates. Recently the PLC's started an unknown issue and fails to send email out anymore. I use the Mail_Send function block from Omron to send emails. The only Error ID i can get is 2005, with status being "Connection to SMTP" failed. Looking at the troubleshooting guide, i cannot find anything to do with error id 2005, in fact its missing. There is 2004 and 2006 but no 2005. I've tried all the obvious thing like, power cycle, redownload the whole project, create a new instance of Mail_Send function block etc. Nothing seems to have fixed this unknown issue. Our IT department did a full check on their side and nothing seems to be out of order. I can still remote into the PLC, so i dont know what exactly is the problem. Has anyone came across this error ID before? Any ideas why this might have been happening? It was working well until few weeks ago and nothing changed and this suddenly started. Any input is really appreciated. Thank you.

  20. GOT2000 as MODBUS TCP slave

    I have this setup: FX3G CPU connected to GT2103 through RS422 (CH1). GT2103's ethernet port connected to LAN and set up as modbus TCP slave (CH2). I want to read/write PLC word devices using a modbus TCP client, from a PC. The HMI is acting as a gateway between PLC and PC. I used the Device Data Transfer function to send PLC's D register values to GT's internal GD registers. D0....D9 ==>  GD0....GD9 After some tries, I get valid response from the modbus slave. Reading the holding registers 0....9 (40001....40009), I get only zero values. Those registers can be written back with different values, correctly. I'm sure I didn't understand correctly the modbus address mapping to GT's internal memory. Can anybody help me? Thank you.
  21. Hello everyone    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure.    Thank you

  23. Hi I am looking for a way to read and write data from PLC omron words, bits via FINS or EtherNet/IP protocol using python programming lang. Does anyone have any results in this? I really want to see your work, because all my attempts have failed. Thanks.
  24. Hello friends, I am an Omron PLC user, but have never used modbus before. I have to connect an Omron CP1L-m to Beckhoff bk7300 via modbus serial gateway. 2-wire RS-485 connection (CP1W-CIF11). I have seen an easy to use Modbus RTU master for CP1L CP1H CJ1 CJ2 CS1 but the examples are not for dual port CP1L-m. If I change the PLC model "CP1HCP1LModbusDualPort" to "CP1L-M", the compiler tells me a lot of warnings about variable types. Is Modbus RTU Master easy to use for CP1L CP1H CJ1 CJ2 CS1 compatible with CP1L-M dual port (port 2)? I have tried to use it but it didn't work, error 02, illegal function code. Somebody could help me? Thank you Enric
