Check if the real time models are sending data to DAQ
1. Open sitemap on an workstation
$sc $medm sitemap.adl
2. Open CDS screen
3. Open GDS_TP screen of each model (blue buttons)
4. Check that "DC Status" is 0x0
DC status |
What to do |
0x0 |
Good status! |
x4000 |
It is OK. Data is being sent and you can leave it. A master IOP gets this error when the timing synchronization is fucked up. |
x2000 |
It is OK. When the master IOP's timing is not synchronized properly, their slave models show this code. |
0x2bad |
Bad. The real time model is not sending data to the data concentrator machine, k1dc0. Go to (1) |
blank |
Bad. Channels are not registered to send to k1dc0. Go to (2) |
(1) When DC status is 0x2
ssh <FE macehine name such as k1pr0> sudo /etc/init.d/mx_stream restart
mx_stream process will automatically start up again, and the DAC status will be cleared.
(2) When DC status is blank
1. First check
make sure the model's channel list is registered in master.
t cd fb emacs master
Check if
- tpchn_modelname.par
- MODELNAME.ini
are written in the file.
2. If master is ok, but still blank or if you changed master file
ssh k1dc0 ps -ef | grep daqd
Check the process number of daqd. There may be two or three and pick the first and left number (###).
kill ###
daqd process will automatically start up again, and the DAC status will be cleared.
3. If neither above did not work
Reboot the data concentrator:
ssh k1dc0 sudo reboot
Wait patiently until k1dc0 restarts.
