Figure 10:
Example network topology with process bus, redundancy and IEEE
1588 v2 time synchronization
The process bus option is available for all 615 series IEDs equipped with phase
voltage inputs. Another requirement is a communication card with IEEE 1588 v2
support (COM0031...COM0037). However, RED615 supports this option only with
the communication card variant having fiber optic station bus ports. See the IEC
61850 engineering guide for detailed system requirements and configuration details.
2.7.4
Secure communication
The protection relay supports secure communication for WHMI and file transfer
protocol. If the
Secure Communication
parameter is activated, protocols require TLS
based encryption method support from the clients. In this case WHMI must be
connected from a Web browser using the HTTPS protocol and in case of file transfer
the client must use FTPS.
