Thanks, Kevin for the info! We have now decided to go ahead with OMS MAXv cards.

>> Hi Mrinal,
>> There is now a 10-axis version of the MAXnet, so you could use just 2 of them. The MAXnet driver inherits from asynMotorController, so it should definitely support multiple controllers in the same IOC. Each is a separate asynPortDriver object with a different asyn port name.
>> If you are planning to use this on a beamline that already has many VME cards like the OMS MAXv then I wonder if it is the best solution. You will need to build a box with power supply and connectors for the MAXnet, while adding from more MAXv cards is simpler. If you want an Ethernet solution there are more powerful controllers available that already have nice packaging.
