DAQ frame writers

The frame writers instability cleared up overnight without us doing anything. Today fw1 was more unstable than fw0 (one fw0 restart, three fw1 restarts). Still a far cry from fw0 restarting every few minutes yesterday afternoon.

DAQ EDCU connection to digital video channels

After the power outage the DAQ EDCU would not connect to any digital video channels. Today I remembered that the EDCU only uses EPICS gateways to access IOCs on other subnets. The gateway between the H1AUX lan and the H1FE lan was not in the start script. I started the gateway and corrected the script. The only channels not connecting to the EDCU are now the end station HWS channels.

HWS code at end stations

Nutsinee, Jim, Dave:

When we tried to start the HWS EY code ('python run_HWS.py') on h1hwsey, the EPICS IOC started with both ETMY and ETMX channels (though only the ETMY channels had valid data). This appears only a problem with the new python based system at EY, EX only runs ETMX channels. We'll continue this tomorrow.

SUS PI work

Terra, Rich, Jeff, Carl, Betsy, Tega, Ross, Dave

model changes were made to h1susitmx, h1susitmy, h1susbs, h1susitmpi, h1omcpi. DAC allocations were changed, SHMEM IPC added for binary data exchange, new quad master, new C code. There were several rounds of model and DAQ changes.

ETMY HWWD

Dave, Jim

We are unsure if the hardware watchdog unit at ETMY is working after restoration of power. One sure way is to power cycle the unit and monitor the LEDs for the startup sequence, but that would power down the ISI coil drivers. We can check if the code is running by disconnecting one of the monitor cables and checking for the LED error. We'll test some more on the test stand before risking ETMY.

DTS

Jim

The DTS was powered up and made fully functional. Interestingly like H1 some front ends wound up with the incorrect time because the boot server had not synced up. We'll remember to check on that in future (Tega got compile errors on x1lsc0 because of this).
