Suitable method for labview communicate with multiple Robot.
1. PC SDK (This the most I familiar with. And can control a lot of thing like direct modify RAPID variable, read execution status etc. But so far I only can read RAPID variable and cannot write to RAPID variable in labview.)
2. Data Socket Messaging ( This I need receive data send from PC and manipulate in RAPID code. also each data send got limit byte? And can some one advice I can read the execution status by using this method?)
3. OPC (This not familiar and anyone can share some information about this?)
4. RS232 ( Don't know this method can control multiple robot or not.)
Appreciate if some one can share the idea.
