System description - SmartIntego specifications

This system specification describes the connection of a SmartIntego network to an existing integrator system via an RS-485 bus.

Basically, there are two different phases that the system can be in:

• Initial setup and configuration changes
• Operation:

Initial setup and configuration changes

If you are connecting a SmartIntego system with an RS-485 bus for the first time or want to change its configuration, you need a configuration device (SI.GN.CONFIG.EC) to transfer the initial setup or the change with the RS-485 bus.

Operation:

During operation, the controller of the integrator system is connected to the SmartIntego routers via an RS-485 bus. The SmartIntego routers communicate wirelessly (868 MHz in WaveNet) with network-capable SmartIntego locks, which then close or open depending on authorisation.

On an RS-485 bus, only one station may transmit at a time. If more than one participant tries to transmit at the same time, this leads to a conflict. In order to resolve conflicts independently and reduce the load on the RS-485 bus in the event of errors, SimonsVoss SmartIntego nodes (SI.GN.CR/SI.GN.CONFIG.EC) automatically restart if one of the following conditions occur at the node:

• Three conflicts occurred consecutively at the same node.
• The node could not detect a signal for several seconds.
