Appendix A.5. SSL/TLS for Secure Connection
SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a security technology for establishing an
encrypted connection between a server and a client. This allows the secure transfer of data across
untrusted networks.
These functions are supported on the following:
FS-QS-1010 or FS-QS-1210 with a serial number starting with 14 or later (indicating the year it shipped).
FS-QS-1011 or FS-QS-1211 with a serial number starting with 15 or later (indicating the year it shipped).
Minimum BIOS requirement: 2.6.1
Appendix A.5.1. Configuring FieldServer as a SSL/TLS Server
The following example sets the FieldServer to accept a secure Modbus/TCP connection on port 1502.
Appendix A.5.1.1. Simple Secure Server Configuration
Add TLS_Port parameter in the connections section of the configuration file and set to a port number
between 1 – 65535.
Connections
Adapter , Protocol
, TLS_Port
N1
, Modbus/TCP , 1502
This configuration sets the FieldServer to accept any incoming connection but will not request a client's
certificate for verification. This means that the FieldServer end point communication will be encrypted but
not authenticated.
The FieldServer will send an embedded self-signed certificate if one is requested by a connecting client.
If a remote client requires a certificate, then request the smc_cert.pem certificate from Sierra Monitor
Technical Support and update the remote client's authority as per vendor instructions.
