  1. In Examples there is UniCAN example "UniCAN for CanBus between masters" and it does work. But there is MI 0 what stores UniCAN Send Status, problem happens when it turns 1 "network is busy". After that, no communication. Only way to restore communication is PLC OFF and ON cycle. I wonder maybe there is some little less destructive way to understand when communications can be restored ? Maybe use some SB's or SI's ?
  2. I am stuck with trying to implement a servo motor, and not sure how to go from here. I have been using the example programs from the unitronics and i cannot get the programs to say the servo is connected. I have connected the CANBus wires according to the picture that i have attached that i found on the unitronics website. My group has never dealt with CAN networks before so we are all starting from scratch. I believe i have to use UniCAN Nodes but am not sure, currently i am just trying to just get the example program working, I am using the "Go to Position By Velocity Block" program. When I
  3. Hello, I have an application running at one of my customers, which there is a V1040 PLC communicating via Canbus with 7 EX-RC1 nodes of which two modules have been installed recently. Each EX-RC1 has a couple of expansion modules connected to it and exchange digital and/or analog data with the PLC. I have followed all the instructions on how to install and configure all the devices, and my application was working fine with 5 EX-RC1 nodes. The problem is, when I installed the others two nodes, my application started behaving strangely: The data (only MI's) coming f
  4. Hello all, We would ask you for help or advice, we have some problems with communication between this two PLC-s V1210 ( moduleV200-18-E46B) and remote I/O EXF-RC15 via CAN bus. We control with 5 servo motors (Yaskawa), two of them is controlled by V1210 and other 3 by EXF-RC15. Everything keeps smooth when we control only 2 motors which are attached to V1210. Problems starts when we finish programming some of other three motors controlled by EXF-RC15 - (when we need communication between this two PLC-s’9. For example when we push on run bit for one motor (Button on V1210 displa
  5. Hello, I am working on a project with the V130 PLC, I have 6 separate actuators connected to my slave configured PLC which communicate over CANbus J1939. I have trouble with controlling the actuators in a consecutive way, some of the times the actuators respond to the command that I send them and sometimes not. I think it might be related to the configuration of the J1939 PGNs on Visilogic. If someone can help that will be great, I am attaching my configuration of transmit and receive PGNs. Thank you, Yom
  6. 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
