ICE block. The block number attribute must also be defined within the range of 1 to

Bailey system will receive data from this block at the ring and node address of the Bailey
interface, module two and block number defined by the block attribute.
engineering units code is a number used by the Bailey consoles to index into a table of

QUALITY tag of this block will be set bad if writes to the block input(s) do not occur within the
Exception Report Output Max Time setting of the block. When this occurs, bad quality will
be written to the CIU and therefore propagated to the users of the block data within the
Bailey system. The quality can also be set bad by writing a one (1) to this tag.
