Subsystem Integration
* Naming convention
* Simulation
* File system
* Standard hardware interfaces
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Naming Convention
* Process Variables located by name -Names MUST be unique
* Naming convention should apply to physical devices – not just control system. The same names should be used consistently in drawings, labels, documents and so on.
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Naming Convention
* A-Z (upper case letters)
* 0-9 (numerals)
* : used to separate structural parts of name
* - used to delimit distinct elements
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Naming Convention
DDDD-TT-CCCCC-NN:SSS:RRRRRR
device sub-system record
(optional)
domain (physical location) MICE
technical area eg. HY, RF, VA …
component eg. VALVE, identifier (01 -99)

Example Record Names
* MICE-RS-RDMON-01:RATE radiation monitor : dose rate
* MICE-VA-VALVE-01:STA vacuum valve : status
* MICE-VA-PIRG-03:CTL:SP pirani gauge : control relay : setpoint
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Simulation
* EPICS database with ‘soft’ records ie no hardware
* Allows you to build test and demonstrate client side applications
* Should not be too realistic

Standard Hardware Interfaces
* EPICS supports many different hardware interfaces. To keep systems as compatible as possible the use of Hytec 9010 IOC and IP modules is recommended for most applications.
* For more complex situations specialised systems such as VME crates may be necessary. This approach will require considerably more software expertise to develop and integrate.

Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Standard Hardware Interfaces
* The Hytec 9010 IOC supports upto 6 Industry pack (IP) interface modules.
* Suggested IP modules are:
* IP-ADC-8401 8 channel 16-bit ADC (+/- 10V)* IP-DAC-8402 16 channel 16-bit DAC (+/- 10V)* IP-SIO-8505 16 channel buffered digital I/O

ALH – alarm handler Hierarchical monitoring and recording of alarm conditions
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Channel Archiver (3.13)• Provides historical archive of configured process variables.• Dead-band set in the database to prevent recording noise.• Export data to different file formats• Web-based user interface
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Channel Archiver (3.14)• Improved storage and retrieval system• BUT – fewer interface options to date
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
BURT – backup & restore tool• Saves snapshots of
sets of values that can be restored later
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Strip Tool
Provides chart recorder style plotting
Multi-channel
Fully configurable scaling
Can also plot historical data from the archiver
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
probe• Monitors a single PV – useful for debugging
Presenter Name
Facility NamePete Owens MICE Controls & Monitoring Workshop 25th September 2006
Display Manager
Used to generate graphical control and monitoring displays from pre-defined widgets.
Several to choose from: EDD/DM, MEDM, EDM, DM2K
EDM is currently the most actively developed display manager
A limitation all of these display managers is that it is not possible to add intelligence or data processing to the application. This must be done either in the IOC or in a separate client application.
