Multiple Rings

3.1 Sub-Ring

The Sub-Ring concept enables you to easily couple new network segments
to suitable devices in existing redundancy rings (primary rings). The devices
of the primary ring to which the new Sub-Ring is being coupled are referred
to as Sub-Ring Managers (SRMs).

SRM = Sub-Ring-Manager

Note: The following devices support the Sub-Ring Manager function:
The SRM-capable devices support up to 4 SRM instances and can thus be
the Sub-Ring manager for up to 4 Sub-Rings at the same time.
In a Sub-Ring, you can integrate as participants the devices that support
MRP - the Sub-Ring Manager function is not required.
