This afternoon we tested the HWWD and new SWWD side-by-side at EY.

HWWD: the HWWD unit is connected in monitor only mode. Its front two monitor ports are cabled to the main-top OSEM satellite amps for ETMY. Its binary in and out cables are connected to ports 24-31 on the binary input and binary output chassis for ETMY. 3 of the 4 front panel BNC ports are connected to spare BNC ports on h1iscey's PEM AA chassis. The back RMS monitor BNC port is also connected to a spare BNC port on the h1iscey PEM AA chassis. We configured the system with a trip point of 110mV and a trip time of 2.0minutes.

SWWD: the h1iopsusey model was built this morning with the latest SWWD parts using RCG2.8.4. The hard-coded RMS trip point is 110mV.

h1susey: the h1susey model was modified to include a HWWD part to communicate with the unit via binary in/out. This required h1susetmy to be compiled against RCG-branch-2.8 to use the new part.

Jeff excited BSC10 at EY using the HEPI actuators. He will post the details in a separate entry. We were able to transition both the HWWD and SWWD to their count-down-to-trip state within the same second. In the attached dataviewer plot. Top Left: the analog voltage from the HWWD back RMS port (being read by h1iscey). Lower Left: is the EPICS channel from the HWWD part in the h1susey model. Top Right: F1 RMS EPICS channel from the SWWD model. Lower Right: output of the SWWD RMS port.

Within the same second, the HWWD turned on its PD front panel led and the SWWD transistioned its output from 1 (good) to 0 (bad). The HWWD RMS value was about 95 at the transition (950 on the plot but the h1iscey PEM AA chassis has an internal gain of x10).
