End Station PI models WP5785

Terra, Betsy, Jim, Dave:

The end station PI models (h1susetmxpi and h1susetmypi) models were changed this morning to permit them to drive the PI inputs to the ESD drives. Prior to this change these channels were being driven by the main quad models. The process was:

remove the drive of the last two channels of the last DAC from ETM[X,Y]

restart the ETM[X,Y] model (to free up the DAC channels)

add the last two DAC channels to the ETM[X,Y]PI model

restart the ETM[X,Y]PI models

Now that the PI models are driving the ESD low voltage inputs, it was important that they stop driving if the main Quad model has stopped driving its DAC channels through either a MASTERSWITCH switch to OFF, or a WATCHDOG trip. This requires two shared memory IPC channels to be added to the ETM[X,Y] models. To get the MASTERSWITCH channel out of the QUAD_MASTER.mdl model, this was changed to add an output port. For the end station models this was plugged into the SHMEM IPC senders, for the corner station ITM[X,Y] this was terminated.

Code checked into SVN r12907

First Version of ITM PI model installed at LHO

Dave:

The first version of the corner station SUS PI model was installed on h1susb123 in the remaining core. This is a 'work in progress' as it does not have any input or outputs and at the moment is essentially a place-holder. This completes the increase in H1 models (along with h1ngn) and brings H1 model total to 104

DAQ Restart

Jim, Dave:

The DAQ was restarted at 14:57 PDT to:

• sync up with SUS ETM[X,Y]PI changes
• add new H1SUSITMPI model
• add DAQ and FEC EDCU entries for the new h1susitmpy and h1ngn models

The DAQ restarted cleanly with no problems.
