OAK RIDGE NATIONAL LABORATORYU. S. DEPARTMENT OF ENERGY

Overview

HPRF IOCs

Cryo IOCs

Soft IOCs

Alarms

Other Shared stuff


IOC Snapshot View of My Tasks


HPRF IOCs (not including the Ring)

Location: $IOCTOP/linac/HPRF

All running 3.14.8.2

Some planned updates to the PLCs might require database changes Black heat changes Write of timing pulse value

RF Leakage detector is being planned.


NC HPRF IOCs

Talk to HVCM (modulator) and transmitter PLCs using etherIP

Timing, utility modules, etc.

RF Windows


SC HPRF IOCs

Talk to HVCM (modulator) and transmitter PLCs using etherIP

Timing, utility modules, etc.

Beckhoff – Cooling, Bias power supplies

Tuning motors


Cryo IOCs

Location: $IOCTOP/linac/cryo

Herb has already taken this over


Cryo IOCs

Talk to PLCs via EtherIP

Also LVDTs and v460s for levels and temperatures

Lots of cpid records. Herb’s the expert on those.


How to Find Soft IOCs

Server

Location

(But if you’re looking for the location of the server, you’ll have to ask Greg or Sean.)


Alarm Soft IOCs – $IOCTOP Part

Herb will take over the cryo ones, he’s already worked on those.

Maybe the HPRF ones go with the HPRF vxWorks IOCs.

These do the voice and summary, probably go with $SHARE soft_alh.

ICS Stuff – IOC heartbeats (and a few PLCs), heartbeat delays and utility modules.

Other systems – maybe system owners should take over.

Location: $IOCTOP/Alarms


Notes about alarm soft IOCs

The shared part is in $SHARE/soft_alh. Has scripts to build soft IOCs and templates for

databases and edm scripts. I’ll talk more about this later.

File structure and configuration syntax are explained in ?????


IOC Heartbeat Alarms

The configuration files are ICS_IOC_HBt_Soft.xml ICS_IOC_HBt.xml

ICS_RF_IOC_HBt.xml in

/ade/epics/iocTop/R3.14.8.2/Alarms/ICS/<vers>/alarmCfgs where <vers> = R1-0-8b now.

Heartbeat alarms use the IOC access security setting to enable or disable the IOC heartbeat alarm.


IOC Heartbeat Alarms, continued

The idea was that you should enter an elog entry when you changed the access security state.

Click on the scroll icon to bring up the change screen.

Hidden behind this screen:• a sequence that waits for the “COMMIT” and sends the temporary values to the real values• Delphy’s script that sends a message to the elog – also on the “COMMIT”.


IOC Heartbeat Alarms, continued again

You can send the same message to a group using the group function. (Click on the Group summary text square and then select IOCGroup.)

See instructions on the IOC Status Snapshot screen for more functions.


Heartbeat Delays

Configured by a script that builds a heartbeat delay configuration file and a heartbeat delay substitution file database from an ordinary heartbeat soft alarm configuration file.

So, when you add an IOC to the heartbeat delay configuration file, you need also to rebuild the heartbeat delay soft IOC.

Heartbeat delays are automatically cleared upon IOC reboot.

But is this really useful?


Heartbeat Delay Screen


ICS Soft IOCs (other than soft alarms)

ICS_Tim:IOC_Linux2 (Dave T.)

ICS_Tim:IOC_Linux3 (Dave T.)

ICS_Tim:IOC_linux_lmt To send timing limit changes to the elog. (Ask Dave T.)

ICS:IOC_linux_pps_bypass To send PPS Bypass status changes (soft PVs) to the elog. (See Linac RF status screen.) (Xiaosong)

ICS:IOC_linux_groups To change IOC operating status for a group of IOCs.

ICS:IOC_linux_eng_scores No IOC Left Behind.

ICS:IOC_Linux_RF_Scopes (Alan Justice)


PPS Bypass Status Changes

I haven’t seen this in use for a long time.


IOC Groups

I don’t think anyone uses this but me.


No IOC Left Behind

Location: $IOCTOP/SNS_softIOC/engScoreApp

It’s supposed to remind IOC engineers to clean up their IOCs, upgrade their systems, get rid of bad PV references, etc.

It’s associated with some cron jobs to run the accounting scripts (run and look at caSnooper, for example) and send an annoying message once a week.

Does anyone look at this?


Cryo Soft IOCs

Cryo_ICS:IOC_linux1 MV status

Cryo_ICS:IOC_linux_pumpdown Pumpdown sequences

Cryo_ICS:IOC_linux_heater Heater sequences

Cryo_ICS:IOC_linux_jtoff JT Off sequences


Cryo_ICS:IOC_linux1

Location: $IOCTOP/Cryo_softIOC

Manual valves. See CHL He Gas Storage screen CHL_GM_storage.edl.

calc records for cryo displays

Herb has done lots of this already.


Manual Valve Screen


Cryo_ICS:IOC_linux_pumpdown


2K Backfill, 2K pumpdown, cryo pumpdown, 2K trip sequences.

Sequences are explained on the edm screens used to control and display status. (Subatmospheric cold box on Cryo overview; choose Cryo conditioning; then Pumpdown; etc.)

The IOC name is too long for autosave. I will change it if I have a chance.

I guess Herb gets all of this.


2K Conditioning


2K Pumpdown Checklist


2K Backfill


Cryo Pumpdown


2K Pumpdown


Cryo_ICS:IOC_linux_heater


Heater sequences. The heaters regulate the heat going into the 2K cold box, which works best if it doesn’t change too much. A pressure PID loop controls the total heat, and the heat to a cavity is adjusted based on the RF load in the cavity.

See SCL_heaterSeq_overview.edl

I guess Herb gets all of this.


Cryo Heater Sequences


Cryo_ICS:IOC_linux_jtoff


JT Off sequences. Ask Herb what they do.

Herb gets this, too.


JT Off Sequences


HPRF Soft IOCs – Status

ICS_HPRF:IOC_linux1 Normal conducting linac status

ICS_HPRF:IOC_linux_scmb Medium beta linac status

ICS_HPRF:IOC_linux_schb High beta linac status


Linac RF Status


HPRF Soft IOCs – Power Limits

ICS_HPRF:IOC_linux_pwrlmtNC Normal conducting power limits

ICS_HPRF:IOC_linux_pwrlmtMB Medium beta power limits

ICS_HPRF:IOC_linux_pwrlmtHB1 High beta power limits 1

ICS_HPRF:IOC_linux_pwrlmtHB2 High beta power limits 2


Why all those soft IOCs?

It turns out if you have too many sequences running in one soft IOC, some of them don’t start properly.

I might have fixed this problem by putting delays in between starting sequences, but I never went back to retest it.

While I’m here, I’ll talk a little about name lengths. (autosave)

And beware tight loops in sequences, especially in soft IOCs.


HPRF Soft IOCs

Lin_RF:IOC_linux_refLine Reference line

ICS_HPRF:IOC_linux_startup HPRF startup and shutdown sequences

ICS_HPRF:IOC_linux_xmtrlmt Transmitter PLC parameter check sequences (mostly limits)

ICS_HPRF:IOC_linux_tunctrs Count tuning motor movements


Miscellaneous Other Soft IOCs

FE_Ctl:IOC_linux_resume Front End Resume sequences

ICS_Diag:IOC_linux_FBLM Set up for Andre Liyu

CF_TA:IOC_linux_hg_acc Mercury accumulation

CF_ST:IOC_linux1 Power Use Monitor


FE_Ctl:IOC_linux_resume

Location: $IOCTOP/FE_softIOC

Front End Resume sequences

I created this because Alan Justice was too busy, maybe it should be his.


ICS_Diag:IOC_linux_FBLM

Location: $IOCTOP/FBLMs

I created this for Andre Liyu, I don’t know anything about it. Or who might have taken it on.


CF_TA:IOC_linux_hg_acc

Location: $IOCTOP/Tgt_softIOC

Mercury accumulation – ask Herb and Joe Devore about this one.


CF_ST:IOC_linux1

Location: $IOCTOP/CF_softIOC

Power Use Monitor – either Delphy (who created a similar soft IOC) or Marnelli could take this one.
