Issue
How does SP-C communicate with grouped TKE controllers?
Product Line
EcoStruxure Security Expert
Environment
- Security Expert 4.0.128 (or higher)
- Security Expert Controller 2.08.582 (or higher)
- TKE Controller (American) v2r0 (only supported version)
- SX-ELV-HLI-TK license to enable the integration
Cause
ThyssenKrupp TKE IP address configuration process occurs in the back-end.
Resolution
The integration operates over IP and the connection is established by the SP-C controller firmware based on who answers the heartbeat messages sent out. You do not need to input the IP address of the TKE controllers.
In the TK environment, our SP-C controllers take the place of 'Security Server' as seen in the image below.
When controllers are grouped, one TKE Controller per group is designated as the Master. It is the lowest online Car ID in each group. All comms will pass through the Master. Security Server sends out a UDP broadcast message and TKE replies to it, Security Server takes note of the device's IP address and subsequent data messages are sent to this address.
What happens if the connection is lost from the Master:
Offline scenario 1: If Elevator 1 was the Master from the ES Group 1 and it fell offline, then Elevator 2 would become the master and it would start replying to those heartbeats with its IP address, Security Expert takes note and starts sending messages there instead.
Offline scenario 2: If we can't communicate with them at all (legitimately offline), then TKE's default behaviour in 'Loss Of Security Communication Mode' is to free all DED/DEC/Kiosk buttons. This is configured on the TK Elevator's end.
