  1. Keyence KV-B8XTD beginners question

    There was no error shown. And yes, I should have been able to switch to run mode, but I wasn't. At least I was lucky finding it. The end unit was the first unit I exchanged...  
  2. I'm trying to make my first steps with a Keyence GPIO unit called KV-B8XTD connected to a KV-7500. I'm using the KV-Studio 10 for control. The only thing I want to do is to switch an output of the GPIO from low to high. I set the KV Studio to "Monitor", open the KV-B8TXD and set some outputs (see image) I would assume that OUT0, OUT2, OUT3, OUT6 and OUT7 on my B8XTD are showing +5V but they don't. All outputs stays at 0V. What is going wrong? Do I misinterpret the "I/O unit monitor" if I assume it is meant to be used for setting the output signals?   Uwe    
  3. Keyence KV-B8XTD beginners question

    I found the problem. It was a faulty end unit(KV-B8XTD). After exchanging it my software(and the KV-7500) work as expected. Thank you for your support!
  4. Keyence KV-B8XTD beginners question

    "Convert" shows no errors. Error Status is "None". But the bottom line status still shows "/ PROG" even if I press "Start Monitor" (F4). Is my PLC broken??
  5. Keyence KV-B8XTD beginners question

    I wrote a test program with two commands: 1. "A 0" (reading from IN_0) and 2. "O 100"(writing to OUT_0). Is that correct? (I was not quite sure how to use an internal bit to drive my output...) I would assume that if I supply +5V to IN_0 I should see a reaction on OUT_0. Right?   But there is another issue: It looks like I cannot start my PLC program. If I press the "RUN / cont. scan" button nothing happens. The "PROGRAM / stop" button is still highlighted. Additionally the status bar keeps showing "- PROG" but it should switch to "RUN", I think. Can you verify? (I set the "PROG/RUN" switch of my 7500 to "RUN" otherwise I get a message that I cannot switch to run mode)  
  6. Keyence KV-B8XTD beginners question

    Thank you for the information! Now I have 4,63V at OUT0 but unfortunately it does not change to 0V if I turn the output to ON. Is this I/O unit monitor the right tool for setting the outputs? Or do I have to set it via a Ladder program?
  7. Hello! I want my KV-7500 to talk to a Windows PC via ethernet. My setup is: A KV-7500 (without end unit) and a Windows PC running KV-Studio 10.0. I checked the USB and the Ethernet ports; both are working. My idea is: Create a socket on the KV-7500 and send some data. Something like this (in C): ------------------------------------------------------------------------------------------ int socket_desc; struct sockaddr_in server; char *message; //Create socket socket_desc = socket(AF_INET , SOCK_STREAM , 0); server.sin_addr.s_addr = inet_addr("123.123.123.123"); server.sin_family = AF_INET; server.sin_port = htons( 80 ); //Connect to remote server connect(socket_desc , (struct sockaddr *)&server , sizeof(server)); //Send some data message = "GET / HTTP/1.1\r\n\r\n"; send(socket_desc , message , strlen(message) , 0); ------------------------------------------------------------------------------------------ Is that possible at all? Where can I put my code in the KV-Studio? I must admit that I'm an absolute newbie so please do not hesitate to give me even obvious hints.
