## Beamlines

## Proposed Beamline Layout

## Control System Architecture	

**Based on EPICS using Two Layer Model**
- Primary interface to CS through VME IOCs
- Use VME64x, IP carriers, IP Modules and  transition board for rear connection
- Hot Swap capability
**Will use PLCs to manage interlocks for  protection**
- Avoids Watch Dogs on IOCs and allow warm reboot of IOCs
- AB Control Logix PLCs for low end applications, eg Vac Valve control
- Siemens S7/300 and S7/400 for high end applications, eg Linac and Cryoplant
**Serial Interface to Instrumentation**
- Potentially several thousand
- Serial support through Stream Device and ORNL Serial
**	**

## Hardware		

**Development**
- Linux for Development
- Running EPICS 3.13.4 will move to 3.14.x
**Consoles **
- PCs running Linux
- Will support Win2000
**IOCs**
- VME64x
- PPC Processor boards
- 	Select processor Autumn 2003
- Will use IP carrier and modules
- Primarily 7 slot crates

## Recent Developments

**Standardised on SLS PSU controller for 1300 PSUs**
- Full digital regulation
- CS Interface through high speed point to point link
**Development of APS/SLS Event System with SLS and Micro Research **
- Move to 2.5Gbit transmission, reduce jitter, enable distribution of RF clock and recovery using VCO
**Development of Application Development Environment**
- Define processes and sequences of building applications
- Local development on Linux PCs, CVS for revision control and server for final check out to operations
- Need to integrate upload to RDB seamlessly
