slave1 -> slave1: command2
slave2 -> slave2: command2
slave3 -> slave3: command2

Hi @shutaozhenzhen,

Here is a proposal, using teoz:

@startuml
!pragma teoz true
main -> main: command1
slave1 -> slave1: command2
& slave2 -> slave2: command2
& slave3 -> slave3: command2
& slave4 -> slave4: command2
@enduml
