Internal/External Data Bus

The MAP 5000 system contains two data buses (BDB), which are used for connection of the
system modules to the ICP-MAP5000 Main Panel.
The Internal BDB may have a maximum length of 3 m and is used for connection of the main
panels in the control panel enclosure (Figure 3.1 Data Bus Connections of the System Modules
on the Internal BDB, page 39).
The external BDB may have a maximum length of 1000 m from the main panel and is used for
connection of the system modules in remote operation.
(Section Figure 3.4 Data Bus Connection of the Control Center on the External BDB, page 41).
