SLC-Aware IOC Review 1 SLC Executive, Message
Service, Database ServiceNov 10 and 11, 2004

• Introduction
• Functional Requirements (Stephanie)
• SLC Executive (Diane)
• Message Service (Diane)
• Database Service (Debbie)
• May need a third session to finish

Introduction

• Prototyping since June. Reviews are way overdue.
• Team in place with weekly meetings
• Designers Diane and Debbie
• Requirement Specification Steph, Dayle,
  Kristi, Linda, RonC (some will be designers when
  ready)
• VMS/Unix Changes, Consultants Tony, KenU, RonM
• IOC CMLOG Additions - James

SLC IOC What it Will Do

• Receive SLC messages and act on them in the same
  way as existing SLC micros for the following
  functions
• Gated ADC Data Acquisition (BPM) beam
  synchronous
• Device Control and Readback (MGNT)
• Cluster Status (IOC Health and Status) (CSTR)
• Maintain its part of the VMS SLC database
• Receive the entire SLC database at initialization
  time
• Receive new setpoints at any time from the Alpha
• Send readbacks back to the Alpha on request and
  periodically
• Send setpoint changes made by external EPICS
  applications to the Alpha
• Goal same amount of network traffic as SLC
  micros

SLC IOC What it Wont Do

• MPS
• BITBUS Power Supply Control
• KISNET Communication
• Micro-to-Micro Communication via Alpha
• SLC-style Analog Signal Monitoring
• SLC-style Digital Input/Output
• SLC-style Error Logging (use CMLOG instead)
• SLC-style Klystron Interface
• SLC-style Video Interface
• SLC-style Timing Interface
• Direct Hardware Access from VMS
• Debugging from VMS
• SLC-Style Fast Feedback Interface
