It is a new feature of Pro-Server EXs.

With Pro-Server Ver. 4.x, you cannot transfer the data from the provider node to the consumer node.
With Pro-Server EX, by setting Collection Type for Data Transfer , the provider node can demand the data from the consumer node and also can collect the data.

However, only GP3000 supports this function.
GP2000/GLC2000/FGW do not support.
An error may be displayed, in case setting the distribution of the collection type with GP2000/GLC2000/FGW.
