Platform Extensible Services / Server
Extended from Inter-Networking Electronics Protocol

ALMBUS is a alarm signaling protocol used to publish, store and recall alarm situations on various building infrastructure devices. The suffix IP indices that this version transmits all data via a IP Networks, for example Ethernet (IEEE 802.3)

Overview

ALMBUS devices are connected together using a ring network (almbus-lo) or, when used as IP protocol, any possible network topology. Every enabled device has the ability to raise alarms, receive alarms and forward/repeat alarms for requesting devices. Each Device can be assigned a unique device identification, alarm groups, restrictions and / or limitations.

The actions taken once upon a device received or raises a alarm are different. for example, The Digital Signage system SignMatic displays a alarm-specific information message on all displays, and refuses to accept any user request to display something else unless all alarms are cleared.

Technical

Devices that are ALMBUS-Enabled (usually part of the ES-Platform) are enabled to issue alarms. the IP version uses UDP Muticast groups to publish and receive alarms, the system can be configured to use perfect forward secrecy to minimize alarm hijacking, however it is strongly discouraged to use ALMBUS on publically accessible networks.
