  1. 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.
  2. 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.
  3. 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
  4. From Allen Bradley New to Omron

    Im used to Allen Bradley. How do I get online with Omron in a way i can use steps to remember
  5. 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.
  6. 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

  12. I am new to automation systems and devices and I just want to know how to connect two HMI's (each one would control different things) to one PLC using Sysmac Studio and NB-Designer via Ethernet. The model of the PLC is NX1029020 and the HMI's are one NB10W-TW01B and an NB7W-TW01B. I searched for info about this topic online but I couldn't find anything that worked for me, I saw an article from OMRON where they connect two NB's to the CP series, but in my case, NB designer doesn't allow me to insert more than one HMI in the same project, I also found something similar on a youtube video that gave me an idea about how to connect multiple HMIs exporting the pks file and importing it to another HMI project but I still can´t figure out how to add both to my PLC. I would thank you a lot if you could help me with this because I know it's not a rare implementation, just I haven´t found the right way to do it. I also leave the links to the Omron article and the youtube video I found. https://www.myomron.com/index.php?action=kb&article=1554 https://www.youtube.com/watch?v=rXx5lut7G9I
  13. Hi, I have quite a noobie question. I want to create a function block to do some simple operations on 2 variables. Both variables are In/Outs (see picture attached). How can I make this function accept variables regardless of the data type? Given these is just simple math I am able to use the same instructions in REAL, INT, UINT, etc. But, the function block only lets me assign one Data Type to the In/Out variables.
  14. Hey all,  So I am looking for some assistance because I am not understanding how the tags on an HMI and within a PLC are linked. There are no 'physical' buttons, just what is on the HMI. It is controlling a chiller. Communicates over Modbus TCP/IP. The PLC is an IDEC. I have some-what worked out how other tags are working when they are words being passed back and forth, but this one has me stumped. I've attached a few screenshots for referral. It looks like the run and unload buttons for the chiller are a single bit/BOOL toggle (but the chiller running latches itself in the PLC when the chiller starts to run). The stop buttons appears to be a parent for the single bit/BOOLs and when it is pressed it resets them all both on the HMI side and within the PLC side.  
  15. Hi there, I have a controller NX1P2-1140DT. I want to control a VFD with modbus serial communication. Can someone help me start from scratch ?
  16. CX-8190-Modbus Srv

    Hey guys, I am trying to communicate between a Beckhoff CX-8190 & a third party fieldbus module that supports Modbus TCP, now I am able to write/read to the fieldbus when twincat is running on the local machine (laptop), but when ever I connect to the device and run the same function block it doesn't write nor read to the fieldbus. I am assuming that the modbus server has something to do with it, so is there a way I can install it to the plc ?
  17. Hi. I have this project with NJ501-1300, in the ethercat settings we add a air valve called EX260-SEC1. When this unit is alone in the ethercat settings, it works without a problem, as expected. But when we add the servos that goes into the machine (ED1F CoE Drive (HiWin)) (Or Ezi-Servo2 ALL), then the air valve goes into error, even if the other ethercat devices are disabled.   We have tried both sysmac 1.45 and 1.47, the plc has 1.43 firmware. We have tried to create a new emptyh project and using different computers, the same error pops up when anything else than the air valve are added to the ethercat config. Any idea how to solve this?
  18. Hi all, I am a new user of VB.net on NA Omron HMI, and I need your help to solve a problem. In my case, I have to get a HMI global variable value in VB.net, but the VariableName is in an other variable (string). For example: Var1=4 Var2=6 VarName="Var1" I worked with a "SetVariable" function to modify the value of different variables, but right now I need to read the actual value, in the example values 4 and 6.  Do you have any suggestion?
  19. KINCO PLC as MODBUS RTU slave

    Hello to everyone. I hope you are doing well. I'm trying to establish a communication between my PC and my KINCO PLC. The manual states it supports MODBUS RTU protocol, so I downloaded two different Modbus Master simulator I found out: Multiway from OMRON and qModMaster. None of them seem to work properly. I attached some pictures of the messages I get. https://ibb.co/f1mCSNt Multiway message https://ibb.co/bP5cX1t qModMaster message I include the configuration of the communication parameters. https://ibb.co/nMty8D9 PLC parameters https://ibb.co/6RTqVfC Multiway parameters https://ibb.co/N1XTccd qModMaster parameters According to the manual, in order to play the role of Modbus master with the PLC it's necessary to configure some instruction blocks (I'm programming in ladder). However, I could not find any block to configure as Modbus slave. I don't know what else I can do. I'm in trouble with this task. Am I making some mistake? Thanks for your attention.  Kind regards!
  20. Hey all, I am having some issues with a Keyence IV2 camera which has Ethernet/IP functionality.  To summarize briefly, it has been configured and reading the data into my PLC (NJ501) into a structure data type.  The issue I'm having is that I cannot control this on a bit level for triggering the camera, etc.  I was reading that a Union type is the way to go, but unfortunately, I stopped getting data into the PLC when setting it up that way.  According to the configuration guide for Rockwell and setting it up in the Network Configurator, I needed to go with the SINT type.  When registering the device, the 8-bit option was necessary since the Input/Output sizes needed to match.  This was predetermined by the EDS file for the IV2. I am stumped as to how to get the data to read into the Union Type, and any suggestions would be greatly appreciated. Thanks, -K  
  21. I encountered an issue that technical support was not exactly able to help me out with, and I wanted to share what I learned here for the next guy. Specifications: Omron NA5 HMI v1.10 connected to NJ PLC via Ethernet Issue: Made a change to a screen where I copied and pasted a button from a different screen.  The screen where the button was copied to had some sort of issue, but it was still able to compile and transfer to the HMI.  It worked for several days until the HMI was power cycled by maintenance, and it was stuck in a black loading screen saying "Initialising Variable System" with a scrolling wheel and green LED on the HMI panel.  It stayed in this loop indefinitely.  The HMI still had a ping, could be connected to from Sysmac Studio, and could be transferred to and from.  Troubleshooting section of the HMI mentions something about initializing failure with a red LED which required a system recovery, but no description for this state. Troubleshooting: Power cycled the HMI, but this resulted it getting stuck back in the same loop. Connected with Sysmac Studio with most recent backup and transferred from the HMI to get the current program.  Before transferring in this synchronize step, I could see a page that was on the target device that wasn't in the source.  I'm not exactly sure how it got there as it wasn't in my backup, but I had green in the comparison list when I shouldn't have.   Reverted program changes, downloaded to the HMI, and power cycled.  Still stuck in black screen with same message. After several other modifications, I eventually had a heavily stripped down program of the backup and downloaded to HMI.  Power cycled with same message. Resolution: In Sysmac Studio under HMI View, select HMI from ribbon, select Clear All Memory, confirm the target device, and select OK.  Once this has factory reset, I made sure the IP address was configured as necessary, connected, transferred backup, and all is well with the HMI now.  Even after loading a backup from several months ago, I could not clear this issue without a factory reset. Hope this helps!

  25. Serial communication with KINCO PLC

    Hello to everyone. Nice to meet you all. I am programming a KINCO PLC model HP043-20DT using ladder on KINCO BUILDER. I need to establish a serial communication with my PC. The PLC has a RS485 port which I adapted it to USB to connect with my PC. The PLC allows, at least, two ways to establish serial communication: MODBUS or free-protocol. I've read the software manual and tried to reproduce the examples it provides using the instruction blocks for MODBUS (MBUSR and MBUSW) and free-protocol (XMT and RCV) communications. However, I could not receive the data on the PLC. I could effectively transmit data with XMT from the PLC to the PC and I could verify through a tool called Access Port. In relation to MODBUS, I am using a simulation tool called Multiway from OMRON, however, I get no response from the PLC. If any of you have some experience with this software or this device, I would like to ask you how could I solve the problem. Thank you for your attention. Kind regards.
