63. Communication Network Representation
Stable section ID: S05-CON-007-SECTION-64 · 53 content blocks
The Communication Network Model shall represent physical and wireless communication paths connecting BIOS, Cartridges, sensors, controllers, robots, user systems, and external services.
Network Entities may include:
physical link;
wireless link;
switch;
router;
gateway;
access point;
protocol adapter;
controller;
edge computer;
cloud connection;
network segment.
Each Network shall define:
Network ID;
purpose;
medium;
topology;
protocols;
addressing;
bandwidth;
latency;
availability;
security class;
trust zone;
connected entities;
gateways;
redundancy;
offline behavior.
Example:
communication_network BIOS_Control_Network {
purpose: building_control;
security_zone: trusted_operational;
topology: segmented_star;
- nodes: [
- @Building_BIOS_001,
- @Utility_Controller_01,
- @HVAC_Cartridge_01
];
- gateways: [
- @Control_To_Cloud_Gateway
];
}
Communication relationships shall not imply control authority.
The model shall distinguish:
physically connected;
network reachable;
authenticated;
authorized;
subscribed;
- actively communicating.
- Legacy or insecure devices shall be represented behind identified gateways and network restrictions.
- Communication failure behavior shall be declared for every safety- or operation-relevant participant.
