    Default CR0133 Application download time is very high

    Hi Folks

    Im using a CR0133 to control a construction machine.
    As the application has grown, the time to download the application to the PLC via CAN is taking extremly long. We are talking 5-6 minutes for every download. And then again approx this time too, for the Bootproject.

    Is there a way to speed this up? Work progresses really slow like that and its almost impossible just to change something quick and test it..

    The application size is 36449 Bytes.

    Maybe change something in the Communication Settings?

    Thanks for any advice.

    First, make sure you have the block transfer feature of the comm options enabled. You could increase the baudrate on the CAN network but this will affect all devices on the network, they would need to be changed to the higher baudrate. The RS232 connection is actually faster to download.

    Hi

    Block transfer is enabled and the CAN Bus is running at 500 kbit/s.

    So I really dont see why it should take this long to transfer the 36000 Bytes. Even if the net data rate would be 250 kbit/s, it should go much faster.. So the true download speed must be much lower.


    Are you having similar experiences or is something else wrong in my setup?

    When you watch the download does the first part go quick? Usually its the Create Boot Project that takes all the time. That being said, 5-6 minutes is a long time for a small project.
