Hello, I am relatively new to Unilogic and completely new to CANBUS, and I have a project that requires 2 encoders a single turn and a multi turn encoder. My struggle is with the software and how to generate the position values for the encoder onto the PLC, I have followed all the help guides etc and have uploaded the manufacturer EDS Files for the encoders, but I currently seem unable to get a reading onto the PLC HMI. And I cannot for the life of me figure out what I'm missing or have done wrong. Can anyone help or have any tutorial videos for if I'm missing anything in the Ladder logic or in the CANopen set up. Thanks

Hello all. I am very new to PLC programming and I encountered something a bit out of my scope. Recently, I was tasked to create a program that would be able to read the values of a NOX sensor using CANOpen and Visilogic. Currently I am using a SAMBA PLC+HMI SM43-J-R20. The NOx sensor's model is UniNox 24V 5WK96614H by Continental. I followed the example of a webinar online that showed the steps for programming an encoder. I am unsure of how to know which bytes I would need to program to be able to read the sensor information. Such as NOX ppm, oxygen percentage , lambda, etc. The sensor package did not provide an EDS file. Basically, my question would be how to know which bytes I need to extract data from a sensor? And how to program it? I have attached the pages that have the pertinent information and the program I have so far. I would really appreciate any thoughts or comments for this. Thank you.

OPLC V1040 is used for control Lenze 8400 Highline servo drive. Position of vertically moved linear axis is measured by servo drive encoder and translated to the panel via CANopen. Drive use his own logic for continuous UP - DOWN move changeover. Now only START and STOP command sended to the drive via CANopen. AXIS is connected with 500kBps speed and moved with 0.8m/s max speed. I need to build programmed limit switch (PLS) for control machine valves depending of axis position. It must be switched separately. PLS in UP and DOWN move is different. Now i have 32bit absolute axis position copied to the ML. Problems: 1) how to calculate the axis moving direction by data manipulation with ML; 2) how to STOP axis as much as posible close to the UP or DOWN end position using only ML data and sended via CANopen "stop" command. Any ideas? -
Hi Guys, I have a new project to retrofit a mobile (vehicle) pile driver machine and I'm now in the process of hardware selection. The machine's decentralized control system was based on an obsolete CANopen Master controller made by IFM. It is a special controller for mobile machine applications and designed for harsh environments with excess vibration. Basically the question is: A normal PLC would be a reliable solution or should i use a controller specially designed for that purpose? What I'm thinking is to use a V570 (to be installed inside operator's cabinet) along with some third party CANopen I/O modules and sensors. Does anyone have any experience with using Unitronics PLC's for such applications? (PS) There are a lot of special controllers for mobile applications out there, most of them are based on CODESYS. -
Hello, I'm working on my first CANopen project where a frequency drive is controlled using the Vision 1210. However i can't seem to figure out how i can start this drive. According to the CAN Bus Operation PDF i should be able to control the drive using PDO 1, as it's default mapping is the control command register. To start the drive bit 0 from register 2000 must be set. but how can i set bit 0 using canbus? CAN Bus Operation.pdf FENNER_QDNEO_S2-S3_CANopen 2.00.eds -
Hi everybody. I need some help because I have an issue, trying to use a Beckhoff BK5120 | CANopen Bus Coupler with a V1210 PLC https://www.beckhoff.com/BK5110/ with the next configuration 4 KL1114 DIGITAL INPUT (4 SINKING) 2 KL1408 DIGITAL INPUT (8 SINKING) 1 KL2134 DIGITAL OUTPUT (4 SOURCING) 2 KL2408 DIGITAL OUTPUT (8 SOURCING) 1 KL3061 ANALOG (0-10V) INPUT https://download.beckhoff.com/download/Document/Catalog/Main_Catalog/english/separate-pages/Bus_Terminal/KL3061.pdf The issue that I have is that I've never used a Beckhoff KL3061 ANALOG (0-10V) INPUT and I don't know how to set up the Unitronics V1210 PLC CANopen configuration in the VisiLogic Software. Also, I'd like to know which function can I use to read the analog input. Does anybody did that before? I'll appreciate your help. Thank you. -
Bom dia, preciso urgentemente de apoio; não consigo , não sei como chamar uma saída num bloco canopen - (XN-GWBR-EATON), (XNE-16DO-24VDC-0.5A-P) , interligado com Vision V1040. Qual comando que uso? Como faço uso das entradas e saídas? -/-*/-*/-*/-/-/-*/-*/-*/*-/-*/-*/-*/-/-/-*/-* Good morning, I urgently need support; I can not, I do not know how to call an output in a canopen block - (XN-GWBR-EATON), (XNE-16DO-24VDC-0.5A-P), interconnected with Vision V1040. Which command do I use? How do I use the inputs and outputs? -
I have a CANopen device that sends 7 PDOs. Fortunately I only have to read 4 of these PDOs but one of the PDOs that I need to read has a COB ID higher than the 4 standard ones. So I found the Relocate button in the CANopen configuration FB, changed one of the COB id to what I need. Now the bad news is that it doesn't seem to work. I actually modified the 2nd and 3rd COB id and then enterred by COBid, base 0x2A0, in the fourth one. Compiles fine and downloads and the first 3 COB id work just fine. I have a V570 running OS 4.03 (05) and VisiLogic 9.8.31, should be latest. I have search any and help files, Unitroincs web site, Google but not a single mentioning about the Relocate button. Any help is appreciated. -
Hello! I'm trying to configure CanOpen communication between Lenze ECSxP Posi&Shaft and Unitronics V1210. I want to set the velocity and the position using PDO1. If I give a high level to the fifteenth bit the control word becomes: First 15 bits are control bits (begin from 0) The velocity value is between 16 to 31 bits it means i can store the value using MI. The velocity is effected in the process data telegram in percent of maximum speed. And the position is between 32 to 61 bits. It is carried out in the process data telegram in resolver increments. I want to give values between 16 and 61 bits It is not possible to use MI to store the position value i need DW, however...inside CANopen Configuration block for RPDO Tx i can use only MI only ML or only DW. Could you give me suggestions how to solve the problem? -
Hi Guys, I have a new project which includes among others, the control of five independent servo motor axis for point to point positioning. I want to use a V1040 PLC and control Delta ASDA A2-M servo drives via CANopen protocol. Has anyone any experience of "talking" to Delta servo's with CANopen by a Unitronics PLC? Any feedback would be greatly appreciated!

I'm trying to configure CANopen communication for a first time. NMT Status integer consists four values: 00, 7F, 05, 04. However when i press "Online test" the value is 517 (dec)?!?! - 205 (Hex). Please tell mi what it means, where is the mistake and how to fix it? -
Hello mates! I have got a problem with CANopen connection between my Unitronics V560 and gateway Turck BL20-E-GW-CO. As u see on the picture I attached after connecting my PLC and Turck gateway Err red diode is turned on. In this case, user manual says: "Faulty or interrupted communication between BL20-CANopen gateway and other CANopen. Possible causes: – CAN-BusOff – Heartbeat error – Guarding error – Transmit timeout" "– Check that the fieldbus ends with a termination resistor, if the BL20-CANopen gateway is the last node in the bus topology. – Check the seating of the CANopen bus connector (or the joints in the case of direct wiring). All connections must be correct and properly seated. – Check the CANopen cable for possible damage, and for correct connections. – Check that the correct bit rate has been set. – Check that the NMT-master is still functioning properly." - I have turned on termination resistor (my gateway is first and the last one at once). I even added extra one to PLC between H and L signal. - My connectors seats well - Cables do not have any issues - Bit rate which I set in "COM PORT INIT" block is the same as in gateway - My master PLC (V560) works What can be issue of my problem? How could I cope with that? Thanks for your time. Cheers!

Hello everybody, I've got a question about Unitronics with CANopen. I am doing an internship and have my own project here. It's a Foil test installation with an extruder. Now I have 2 servo controllers (CDE3004) and I want them to communicate with my Unitronics V1040. But I have a little bit trouble understanding the CANopen configuration. The idea is that I can read the parameters from the servo controllers. For instance the RPM, Torque, Power and Errors/Warnings. And that I can control them from 0 to 100% I also found some information concerning the servo controllers; Info about Servo Controllers CAN here are in my opinion the values for CANopen? Or am I wrong with this. maybe someone can give me a push in the right direction with how to set the configuration. (Sorry for my english if it's not quite right) -
We use several workstations that may, or may not be, running at any given time. How well does the CANbus protocols handle a node being offline? -
We have a customer that is interested in using a Murr "Cube67" CANopen bus node in an application with a V570. We've been able to put our hands on a couple of CANopen examples but the documentation is lacking and reverse-engineering the ladder logic has been a bit...frustrating. Does anyone have a real-life example of a application to a Murr Bus Node that they might be able to share? Thanks!!
