  1. 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!!!
  2. Hello Guys, I would like to know if someone in here has made a VB script, there can delete files from the SD card in HMI? the reason why I ask, is I have some data logging on the HMI for our customer, but I would like the data logging to go in a loop so if the  SD-card is full, it will delete the oldest file instead of stop data logging. who is there somebody there can show me an example on a VB for this :)?

  5. NB Data log

    Hi there!  I need to implement a data logging that saves the log in a USB storage for a machine and just started searching for some info about data logging in NB HMIs. Up to now I'm clear about using the Data History function and the sampling method I'll be using but I still have some unclarified doubts about this. 1.- The data log should sample the value of, let's say, a couple of words, each second for an entire day (6:00 am to 6:00 am). NB's manual doesn't say a lot about Storage Type and Buffer Storage in "Save Data History" tab. Does "daily file" mean It deletes the .CSV file daily and it generates a new one? If is it, at what time does this occur? Does "single file" mean it generates a file and won't get deleted? Does this mean the sampling stops when completing the first one? Is "storage period" used to keep the file after the next log begins? 2.- Is it necessary to display the element in order to make the log work? Or can it be placed in a random screen you only enter once a day? 3.- In the "Channel Properties" tab. If I need to get the binary value of a word, do I need to set the max. limit to 65535? 4.- I asume that "Sample points" value doesn't matter when selecting Continue sample mode. Am I right? Thanks in advance, any help is appreciated.

  7. Hello guys I am a beginner in FINS UDP communication and I am trying to do a FINS UDP communication between an omron PLC CP1L-E in client mode to communicate with my PC that is in server mode, I am using the SocketTest v3.0.0 program that is in listening mode and still was unable to receive any information from the CLP, can you help me? The program and some images of the simulation are attached Thanks for reading SERVER PC IP ADDRESS CLIENT PLC IP ADDRESS   tcp socket (1).cxp
  8. Good day everyone, I recently got NB HMI and program it together with my NX1P2 PLC. I got 2 questions I would like to ask. What I'm trying to achieve is to lock all the button after I start my system or during the pop up screen for confirmation. I tried different methods and it doesn't work. Currently I'm using a direct window Pop-Up screen to cover all the button behind it, but I noticed if I drag the pop up screen, it'll move together. So I wonder, is there any correct methods of doing it? Also, the function key for change screen, I use it for Pop up screen but why it only spawn on the top left of the screen instead of the center? Thanks in advance guys!
  9. Hi, I have an Omron NSJ5-SQ00B-M3D Programmable Terminal (HMI) that I am trying to get to communicate with an Omron CJ2H PLC through a DeviceNet module (DRM21) in the main PLC rack.  I don't see how to configure CX-Designer to communicate via DeviceNet.  How is this done?  Many thanks for any help.
  10. NT20 touchscreen broken

    Hi, I have an Omron Nt20S touchscreen and the screen is broken.  The only way I know how to get the program off of the screen is to push two corners at the same time and then go into transmit mode. Does anyone know how to upload a program from this screen without changing it to transmit mode?  I already attempted to replace the screen, but I think the program is stored on the circuit board the screen is attached to. Thanks in advance!
  11. setting date cp1l

    Hi all im currently using the DATE instruction to set the PLC's date and time via the HMI which is an NB7W which i have working but i am currently setting each byte of the words being used in DATE by using numerical inputs in NB designer and entering integer and decimal to set these bits in DATE and its a bit ugly to say the least. is there a way on nb designer to only modify bytes or am i going to have to used full words on nb designer and use MOVD in cx programmer to assign them to their correct byte CURRENT SETUP always on DATE using d50=d53  

    Our C axis which is a rotary axis doesn't perform commanded postion, for eg if we give command of 360 deg, then it will only rotate 359 deg and for next time it will rotate 358 and so on for every rotation. i.e for every rotation its complete degree is reduced by 1 deg.  And system doesnt show any error.  By providing command of 360 deg, if we rotate or axis for 15 times then the last position at which it will stop will he 345 deg.    Please share valuable inputs to resolve that problem.
  13. CJ1M+ETN21 Modbus TCP

    Hello. I'm trying to use Omron ETN21 as master for ModbusTCP protocol. I can communicate with 1 SLAVE UNIT (standard modbusTCP slave) using FB  from It works perfectly. But I have three SLAVE UNITS to communicate to. I'm trying to do this using [524] sample. I have copied SECTION1 to SECTION2 and changed IP number and SOCKET number. But this doesn't work. I would realy appriciate a working sample where OMRON PLC is MASTER for THREE (or more) SLAVES. I'm attaching code file... Thanks. Best regards, Andrej. Modbus_TCP_FB.cxp Modbus_TCP_FB.opt
  14. Hello out there   I've searched for quite some time but unable to find any information helping me through this. I got a Omron PLC NX1P2 where im supposed to setup modbus communication over TCP/IP but so far i've only been able to find information regarding RTU setup. But seen forums mention its possible to setup via TCP/IP Anybody who can help. A program sample would be helpfull aswell. Im a trainee as automationengineer and this is my first encounter with Omron PLC and Modbus so quite new to the field.   kind regards Ivan T.
  15. Hi there! I've been working with NB HMIs with good result. But today I loaded a project to a NB7-TW01B and it feels slow, both offline and online. Switching screens and reading/writing take around 1sec or more. It first had some bmp images created with .bmp and .png files, so I tried using vector graphics instead, but didn't get any better. I don't have another NB to try it right now so I'd like to ask you if you've been in this same situation before or what could be causing this. PLC is CP1L and communication it's via Ethernet. Both devices are actually pretty close (cable is less than 3m) and the previous HMI (Pro-face GP) felt a lot faster. Thanks in advance!
  16. I am currently trying to connect my OMRON NX1P2 1040DT1 (Using CIF-105) to my Unitronics V570 PLC, With my OMRON PLC as Master. It seems as if Unitonics Rs485 only wants a six-wire connection type but my OMRON PLC wants a 2-wire or 4-wire connection, Wondering if anyone has a solution to my problem and can assist me.  
  17. Need help please

    Hi, I am in need of help to fix a software for positioning system on a sawmill. The PLC I use is a CP1E, positioning is done with a E6C2 - 600 pulse incremental encoder. Controlled by weintek HMI. I am having trouble getting my positioning to be exact and sometimes it can vary by as much as +-1/8".  I put the code in attachment, if you look at the "auto_down" section, that would probably be the simplest place to start looking.  I would much appreciate any feedback on possible flaws in my coding or the way I put it together. Thank you, Stephane 4221 V2.4 (2020).cxp
  18. Hi there! I recently discovered this forum and I find it pretty useful for sharing and learning about PLCs. The thing is I'm trying to make a Stack using the SSET(630) instruction in a CJ2M PLC. Reading Omron's W340 manual I saw that PLC memory address for the different stack channels is represented as "00010000" to "0001000F". So, in order to set the last stack word address as well as the pointer's address, how do you know those values? Or am I just misunderstanding something? Thanks in advance!   Edit: Solved, the definition of the stack was wrong!    
  19. Hello, I'm trying to connect a CJ1M-ETN21 as slave Modbus TCP with a Modbus/Dali Gateway. I download from Omron website some FB with ones should be possible. The FB only can be used with the direction unit 0, but we can change some directions inside the FB and can be adjusted to other units. In the download I found this FB: MTCP_ETN_Connect, MTCP_ETN_Fn01, MTCP_ETN_Fn02, MTCP_ETN_Fn03 .... Supposed with connect we can establish the connection with the master, but the FB never make nothing. Should I make some special configurations to use this FB? I appreciate any help. Thanks

  22. String shift register

    Hello all thanks to bits n bytes's date and time to string converter here i have made a nice string output function block for the PLC date and time that i will attach. I'm now wandering how to shift this into a memory card as well as display it on a NB screen. for the NB screen i think i can just used a text box to display the code using 8 words, i sadly dont have a CJ2M plc with me at the moment so i cannot test. for the memory card i have not used these at all yet, is there a special shift register for strings? i cant seem to find it. i will be using this simply for a checklist on the HMI where an operator goes through the list of tasks to perform and ticks them off on the HMI which then logs the time and date they were completed at. do i need to create a shift register using MOV$ with a @destination and increase the count of the destination witch each input? Thanks in advance Date_and_time_string_convert.cxf
