for LocalBus only. Some servers of a client can be Individual Channel
Servers. This means that they have a reserved reception channel on the
CAN chip. This can be considered as they are connected with the mas-
ter DGFC with a reserved serial line. As a result, for example, time-
outs of other nodes do not disturb communication between the master
and its ICS, and time-outs of an ICS do not disturb communications of
other ICS and SCS

Shared Channel Server is a server that shares its reception channel
with another server.
