We have been planning for a while to have the RIXS optics PLC send its mono grating pitch values directly to the LCLS2 DAQ. This was deployed this PAMM, through a joint effort between Zachary L Lentz, Christopher Ford, Margaret Ghaly, and Jyoti, Joshi. The encoder can be selected in the DAQ, at which point it will send triggers directly to the PLC, which responds appropriately up to 60Hz. The plan was to respond appropriately up to 120Hz, but this issue was not caught until nearly the end of the PAMM. There will be follow-up work to get this to work properly at 120Hz.

2.2 ZOS to Rix Optics PLC

Through Joint effort between Zachary L Lentz, Jyoti, Joshiand Margaret Ghaly the ZOS is now controlled by the rix-optics plc instead of rix-motion plc. Zachary L Lentzremoved all the ZOS code from the motion PLC and rebuilt the IOC. Margaret GhalyAdded the ZOS code to the rix-optics. Jyoti, JoshiTested and checked out that the ZOS is working.
