-===== Why using RTRs is not advised in CANopen? ===== 
- 
- 
-CiA, especially the Special Interest Group CANopen is not recommending using RTR Messages. You may ask: why?\\  
-\\  
-The CiA has a paper explaining the contras and giving advice for better solutions. CiA AN 802 V1.0: '''CANopen statement on the use of RTR-messages'''\\  
-\\  
-It can be downloaded free of charge after a registration at http://www.can-cia.org/downloads/ciaspecifications/?1324 .\\  
-\\  
-\\  
-In short the main topics: 
- 
- 
-    * The number of transmit messages buffers supporting CAN remote frames is limited on most so-called FullCAN controllers. 
-    * Implementation of a CAN driver handling RTR is much more complex. On some controllers impossible. 
-    * Some CAN controllers react different on the 'data length' code in the RTR frame and the data frame. This is due to differences in the CAN implementation. \\  \\
