SUMMIT 8800 DESCRIPTION 03
• Used to store all alarm record data and parameters
• Non-volatile memory requires no power source to maintain integrity of data.
• Cannot be written to from any external source: it is read only memory.
• Requires unique software tool to upload the data files via the USB or ethernet port
• Cannot be accessed using any common software tools.
• Integrity of each individual data, audit or alarm record is maintained by the use of a recorded
time stamp and an individual CRC32 checksum for each individual record.
Static RAM Memory (Recorded Data)
• Used to store calculation results. Data that can change on every calculation cycle, e.g. flow
measurement totals and parameter averages.
• Non-volatile memory that requires internal lithium back-up battery to maintain integrity of
data.
• Backup battery is integrated inside the unit and cannot be switched off or removed without
breaking a hardware seal and removing the rear panel of the unit.
• Backup battery capacity is sufficient to maintain data for at least 5 years of normal operation.
• Backup battery condition is continuously monitored and indication is given when replacement
is due.
• Cannot be written to from any external source: it is read only memory.
• Requires a unique software tool to upload the data files via the USB port or ethernet port
• Cannot be accessed using any common software tools.
• Integrity of the data is maintained by the use of duplicate records for each value which are
verified against individual CRC32 checksums for each individual record block.
The SUMMIT 8800 also contains the following types of optional hardware memory storage de-
vices which are integrated in the design of the SUMMIT 8800 but can be removed from the unit.
SD memory Card
• Used to store data log parameters (separate from data logs stored in data flash memory)
• Up to 4GB of data storage or typically lifetime storage.
• Used to store all audit trail data and parameters (duplicate copy of audit trail data stored in
data flash memory)
• Non-volatile memory requires no power source to maintain integrity of data.
• Cannot be written to from any external source: it has an internal coding.
• Requires a unique software tool to upload the data files via the USB or ethernet port or via a
SD slot in a PC
• Cannot be accessed using any common software tools.
• Integrity of each individual data, audit or alarm record is maintained by the use of a recorded
time stamp and an individual CRC32 checksum for each individual record.
• Can be removed from the unit at any time.
