4.5.2
Maximum System
The maximum system contains:
▪ three lines and two line changes
▪ one SIL2 bus coupler
▪ 32 SIL0/SIL2 I/O modules and
▪ a SIL2 power supply at the beginning of every line.
With the help of an additional SIL2 power supply, SIL0/SIL2 I/O modules can be
attached galvanic insulated.
The SIL0/SIL2 I/O modules can be combined randomly.
The maximum energy requirement depends on the used SIL0/SIL2 I/O modules.
If the energy requirement is too high, another SIL0/SIL2 power supply has to be
added.
See "Energy Supply Range” on page 25.
