Currently Diamond has a number of MKS Microvision Plus RGAs deployed on the storage ring. These are controlled by Windows PCs running MKS's Process Eye software via serial. The PCs are connected to VxWorks IOCs running a simple records-based EPICS driver that communicates with Process Eye over serial via streams 2 using a simple, high-level protocol supplied by MKS. Process eye communicates with the RGA using a lower-level protocol.

We are due to deploy Microvision 2 RGAs on our new beamlines and I am currently writing the software support for this. The Microvision 2s have an Ethernet connection, so a soft IOC running on Linux will communicate directly with the RGA without the need for a PC running Process Eye, sending the lower-level commands following MKS's RGA protocol. 

As such I'm currently developing an Asyn driver that effectively replaces Process eye and an IOC and support module to communicate with the driver. 

We do not have MV2s currently deployed and do not have a driver yet, except for the one in development.

However, we are planning to have the first version of the driver in the next few weeks ready to be deployed on one of our beamlines on the next run at the end of June. There will likely be further release with additional features and further development.

Diamond has a driver for that.

The MKS website even shows their units in situ at Diamond. [1]
