dahnuguy Posted December 27, 2010 Report Share Posted December 27, 2010 Is the limit 4 PDOs per node? At 8 bytes per PDO that is 32 Bytes of data sent to each node. Is this the maximum limit of data that can be sent to one node? Is there some way to increase this number? I realize I could play some tricks and shuffle data into a set of transfer bytes,( I could even increment down a row in a data table and put the row data into a transfer array and then send it, but this would be multiplexing and slow and would confuse the receiving node as well, some receiving array would need to be set up in the node and then parse the data using one of the pieces of data as an index or control word.) Direct transfer with canopen and Visilogics is tricky enough though. Just wondering where the limits are. I guess ethernet would be easier with 50 variables per message. or am I missing something?
