The Diamond PGS BlockBuffer is the Second line data communication hub of the system. It communicates via two communication ports:

•    Downstream RS485 port
•    Upstream RS485 port

The BlockBuffer main functions are:

•    Collect data from up to 16 BlockBuffers connected to its downstream RS485 port.
•    Calculate the availability figures of each allocation and the total of the entire system.
•    Send data to downstream numeric displays.
•    Compress the information and relay it upstream on request.
•    Reduce commissioning effort to next to nil using its auto map feature.
