Figure 74: IEC 60870-5-104 protocol configuration settings
The following settings are available for the IEC 60870-5-104 protocol.
IEC TCP Port Number
Range: 0 to 65535 in steps of 1
Default: 2404
This setting specifies the TCP port number to use for IEC 60870-5-104 communications.
IEC Client Address 1 through IEC Client Address 5
Range: standard IP address format
Default: 0.0.0.0
These settings specify the IP addresses for five IEC 60870-5-104 clients.
IEC Common Address of ASDU
Range: 0 to 65535 in steps of 1
Default: 0
This setting specifies the local address of the D90
The address is common to all data in a single ASDU (Application Service Data Unit). The
combination of ASDU common address and IOA (Information Object Address) uniquely
identifies each data item in a system.
IEC Cyclic Data Period
Range: 1 to 65535 seconds in steps of 1
Default: 60 seconds
This setting specifies the rate at which the D90
of whether or not a status change has occurred. This data includes binary inputs, binary
outputs, and analog inputs.
IEC Current Default Threshold, IEC Voltage Default Threshold, IEC Power Default
Threshold, IEC Energy Default Threshold, IEC Other Default Threshold
Range: 0 to 65535 in steps of 1
Default: 30000
These settings are used to determine when to trigger spontaneous responses containing
M_ME_NC_1 analog data. These settings group the D90
