SIAM VME Summary Interlock and Alarm Module

Hardware Description (via
Each fault input can be independently configured by an individual personality module via jumpers and resistors.

A programmable time constant determines how long a fault input error condition must be present before it trips the fault latch. The fault latch delay time constant can be set from 250 s to 105 s. Any fault trip drives the Daisy-Chain output. Systems requiring more than eight fault inputs can be accommodated by concatenating two or more SIAMs via front panel LEMO Daisy-Chain input and Daisy-Chain output connectors. The Daisy Chain input is TTL compatible and the Daisy Chain output is a TTL open-collector output.

IOC for trbcmd

  • An IOC was setup for testing trbcmd on lxhadesdaq
    • This is a proof of principle application
    • An IOC for the CTS will follow soon
