Network architecture and time synchronisation
PTP (IEEE 1588) time synchronisation, Ethernet / PoE infrastructure design and integration of distributed systems.
In distributed measurement and control systems, units must operate on a common time base. Matching sensor data, ordering events and deterministic communication require the network architecture and time synchronisation to be designed together.
PTP-based synchronisation
Sub-microsecond synchronisation over the network with the IEEE 1588 Precision Time Protocol: hardware-timestamping Ethernet PHY / MAC, boundary and transparent clock configuration, grandmaster selection and a GNSS-disciplined reference. A PTP client and local oscillator disciplining are implemented on embedded endpoints.
Ethernet / PoE infrastructure design
PoE (IEEE 802.3af / at / bt) design in which sensors and endpoints are powered and communicate over a single cable; power budget, switch selection, VLAN and QoS separation, prioritisation of real-time traffic; rugged connectors and cabling for industrial environments.
System integration
Bringing devices from different manufacturers onto a common network and time base, protocol gateways, monitoring and logging infrastructure; verification with latency and jitter measurements during commissioning.
