3.5.1.4 Maximum configuration of the CubicleBUS
The CubicleBUS can comprise up to 13 nodes.
These include:
● Trip unit ETU
● Metering function PLUS
● Breaker Status Sensor (BSS)
● COM15
● BDA PLUS
● ZSI module
● Digital output module with switch position left (1st module)
● Digital output module with switch position right (2nd module)
● Digital configurable output module
● Digital input module with switch position left (1st module: "Parameterswitch")
● Digital input module with switch position right (2nd module: "PROFIBUS-Inputs")
● Analog output module with switch position left (1st module)
● Analog output module with switch position right (2nd module).
In practice, only one selection of these modules is usually necessary
