| redundancy_groups.connections.clt_ip | address to local IEC 104 client | IP address | Yes | ||||
| redundancy_groups.rg_name | this identifies the redundancy group | Yes | |||||
| srv_ip | Server IP address | IP address, machine's default IP for a given interface | No | ||||
| port | This defines the TCP/IP port to be used by the server. | default = 2404 | No | ||||
| tls | activation of TLS (see tls configuration chapter for details) | TRUE, FALSE, default = FALSE | No | ||||
