Figure 3. Parallel redundancy protocol (PRP) solution
The device can be connected to Ethernet-based communication
systems via the RJ-45 connector (100Base-TX) or the ber optic
LC connector (1000Base-SX), depending on the product variant.
The device supports the following high accuracy time synchro-
nization method with a timestamping resolution of 4 μs required
especially in process bus applications.
• PTP (IEEE 1588) v2 with Power Prole
IEEE 1588 v2 features
• Ordinary Clock with Best Master Clock algorithm
• One-step Transparent Clock for Ethernet ring topology
• 1588 v2 Power Prole
• Receive (slave): 1-step/2-step
• Transmit (master): 1-step
• Layer 2 mapping
• Peer to peer delay calculation
• Multicast operation
Required accuracy of grandmaster clock is +/-1 μs.
