Attribute | Description | Expected values | Mandatory |
---|---|---|---|
name | this identifies the protocol stack | iec104client, iec104server, tase2client, tase2server, 61850client, 61850server, etc... | Yes |
version | version number of the configuration file | 2 digits x.y => x = major change, y = minor change | Yes |
bind_on_ip | bind on a dedicated local IP address | TRUE, FALSE, default = FALSE | No |
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 |
k_value | Maximum number of outstanding (unacknowledged) APDU's at a given time | default = 12 | No |
w_value | Acknowledge the reception latest after this number of APDU's | default = 8 | No |
t0_timeout | time out of connection establishment | default = 10 | No |
t1_timeout | time out for send or test APDU's | default = 15 | No |
t2_timeout | time out for acknowledges in case of no data messages (t2 < t1) | default = 10 | No |
t3_timeout | time out for sending test frames | default = 20 | No |
orig_addr | Originator Address | default = 0 | No |
ca_asdu_size | size of "Common Address of ASDU" | default = 2 (byte) | No |
ioaddr_size | size of 'Information Object Address' | default = 3 (byte) | No |
asdu_size | maximum ASDU size in transmission direction, if set to "0" => maximum possible value is automatically used. | default = 0 (byte) | No |
time_sync | If set on "TRUE" this parameter allows to synchronize the clock of the local computer by the server. If set on "FALSE", the clock is not synchronized. | TRUE, FALSE, default = FALSE | No |
comm_exec_timeout | Defines the command execution monitoring timeout in milliseconds. The default setting is 20 seconds. | default = 20 seconds (20 000 ms) | No |
comm_recv_timeout | This parameter defines the highest allowable deviation of received command time tag and local clock. If the difference is too big, command is ignored. | default = 0 (disabled) | No |
tsiv | specifies what to do with a time stamp marked as 'invalid' | remove ignore, process, default = removeignore ignore: the time stamp quality 'not synchronized' will be ignored and the time stamp will be processed on regular basis. IV-bit will remain 0 process: the time stamp will be send with IV-bit set to 1 | No |
reset | reset/restart the system on C_RP_NA_1 ASDU (=TRUE) or not (=FALSE) | TRUE, FALSE, default = FALSE | No |
filter_orig | accept commands only originated from an authorized originator (=TRUE) or accept all originators (=FALSE) | TRUE, FALSE, default = FALSE | |
filter_list | List of Authorized Originators | No |
