Figure 91: IEC 60870-5-104 protocol configuration settings
The following settings are available.
NOTE:
Do not set more than one protocol to the same TCP/UDP port number, as this results in
unreliable operation of those protocols.
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, IEC Client Address 2,..., 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. These are
devices to which the D90
Plus
can connect.
IEC Common Address of ASDU
Range: 0 to 65535 in steps of 1
Default: 0
This setting specifies the local address of the D90
Plus
for IEC 60870-5-104 transactions.
The address is common to all data in a single Application Service Data Unit (ASDU). The
combination of ASDU common address and Information Object Address (IOA) 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
Plus
sends updated point data regardless
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 Other Default Threshold
Range: 0 to 100000000 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
Plus
analog data into types:
current, voltage, power, energy, and other. Each setting represents the default threshold
value for all M_ME_NC_1 analog points of that type. For example, to trigger spontaneous
