also checks cable presence & parameter reception rate
• GMT can drop a parameter• GMT can rearrange parameter transmission order
• GMT cannot change payload of parameter

• GMT drops a parameter• GMT rearranges parameter transmission orderWarnings recorded when:
Interlock raised when:• GMT drops three consecutive parameters
• GMT changes payload
Automatic observation by CISC
Never observed…Interlock through BIS

• Pre-op / DIAMON / Post-Op now functional• complete logging functional simple format
See J.-C. Garnier up next
1) Arm loops…2) Send single bad energy in timing editor…
3) Observe…
• Reactive consolidation / maintenance only• New needs = new requests e.g. LS1 SBF tables
Does it actually work?
SMP hardware project will be closed.
