status of seismon epics interface

I've been working on a prototype epics interface to the seismon system. It currently has several moving parts.

EPICS IOC

Runs on h1fescript0 as user controls (in a screen environment). Code is

/ligo/home/controls/seismon/epics_ioc/seismon_ioc.py

It is a simple epics database with no processing of signals.

EVENT Parser, EPICS writer

A python script parses the data file produced by seismon_info and sends the data to EPICS. It also handles the count-down timer for future seismic events.

This runs on h1hwinj2 as user controls. Code is

/ligo/home/controls/seismon/bin/seismon_channel_access_client

MEDM

A new MEDM called H!SEISMON_CUST.adl is linked to the SITEMAP via the SEI pulldown (called SEISMON). Snapshot attached.

The countdown for the P,S,R waves are color coded for the arrival time of the seismic wave

ORANGE   more than 2 mins away

YELLOW  between 1 and 2 minutes away

RED  less than 1 minute away

GREY in the past

If the system freezes and the GPS time becomes older than 1 minute, a RED rectangle will show to report the error.

Just noticed this post, this is great.

Let us know if you run in any bug/trouble with the code.
