2.4 [IEC-870-5-104]
This section provides information required to configure a server application with
the module. Most entries contained within this section are self explanatory An
item of concern is the maximum size of the total database, although it is possible
to configure a database of considerable size, this would not work, as the
maximum Class 0 request may not exceed 2048 bytes in size.
2.4.1 Use IP List
0 or 1
This parameter specifies if the IP address of the host connected to the system
will be validated. If the parameter is set to 0, any host may connect to the unit. If
the parameter is set to 1, only hosts in the IP list will be permitted to connect to
the unit.
2.4.2 Override StartDT
0 or 1
This parameter is used when testing the unit with a simulator or with a client unit
that does not meet the IEC 60870-5-104 specification. After the host connects to
the system, it will send a STARTDT.ACT U-format message to the unit to permit
the unit to start sending data. If the client does not support this requirement, set
the parameter to a value of 1. Set the parameter to 0 if the unit sends the
STARTDT.ACT message.
