    Hello,

    My program has error 3803: Canopen implicit Variable(18): Out of global data memory. variable 'pCanOpenPDO_Tx'.
    I got that error right after codesys forced my to implement some libaries by rebuild.
    And that happened after deleting the last canopen master. And add CAN3 by Can-interfaces
    How can I solve this?

    Thankyou in advance

    Edwin

    I have solved the problem. If you you a plc HY-TTC94 like me. You are standard using internal RAM. This is faster but smal. The error above tells me the RAM is to small so I have to switch to the external RAM. Slower but big. Go to target settings and change the values like the picture and than you are using the external RAM. So the problem is solved. Also a option if you have a plc HY-TTC90.
