The following example writes the value 0 to the hypothetical application specific object entry "[1234:56]" within the object directory of the CANopen node AppNode.

    CPU_INT32U  value;
    CO_OBJ     *entry;
    :
    value = 0L;
    entry = CODirFind     (&(AppNode.Dir), CO_DEV(0x1234,0x56));
    err   = COObjWrValue  (entry, &value, 4, 0);
    :

Note: The example shows a read access with the knowledge, that the addressed object entry is independent from the CANopen node-ID. To be independent from this knowledge, the API function CONmtGetNodeId() may be used to get the current node ID.
