5.6 [I104S] > [IEC-870-5-104]
This section provides information required to configure a server application with
the module. An item of concern is the maximum size of the total database.
Although it is possible to configure a database of considerable size, the
maximum Class 0 request may not exceed 2048 bytes in size.
5.6.1 Use IP List
NO (0) or YES (1)
This parameter specifies if the IP address of the host connected to the system
will be validated. If the parameter is set to NO (0), any host may connect to the
unit. If the parameter is set to YES (1), only hosts in the IP list will be permitted to
connect to the unit.
5.6.2 Override StartDT
NO (0) or YES (1)
This parameter is used when testing the module with a simulator or with a Client
unit that does not meet the IEC 60870-5-104 specification. After the Client
connects to the module, it will send a STARTDT.ACT U-format message to the
module to permit the module to start sending data. If the Client does not support
this requirement, set the parameter to YES (1). Set the parameter to NO (0) if the
Client sends the STARTDT.ACT message.
Note: This parameter must be set to NO (0) if you wish to use the redundant Clients feature.
