[Dsg-hallb_magnets] FYI: DSG progress on direct PLC to Cryocon communication

[Tyler Lemon]

Hello,

To keep the mailing list informed, Brian has been looking into Cryo's PLC code distributed by Nick for communicating directly to PLCs with Cryo-con units.

So far, he's been able to set up and test 2 versions of direct communication: the version from Cryo and a version using Allen-Bradley Add-On-Instruction (AOI) for Modbus.

Findings so far are that:

  *   the Cryo version is more involved to get set up and is slower in communication than the delays set in the routine.
  *   The AOI is quick to set up, but does a lot of extra things that are not wanted or needed.

Best regards,
Tyler
