This parameter specifies the register location in the module's database where
module status data will be stored. If a value less than 0 is entered, the data will
not be stored in the database. If the value specified is in the range of 0 to 8966,
the data will be placed in the modules database.
2.2.8 Block Transfer Size
60, 120 or 240
This read-only parameter specifies the number of words in each block transferred
between the module and processor. Valid values for this parameter are 60, 120
and 240.
2.3 [IEC-870-5-101 Port 0]
This section provides information required to configure a slave application with
the module. Most entries contained within this section are self-explanatory.
Modify each parameter according to the needs of your application:
2.3.1 Enabled
0 = Disable port, 1 = Enable the port.
This parameter enables or disables the protocol port.
2.3.2 Time DB Offset
Time DB Offset : 2000 #DB location of IEC time
This parameter defines the location in the database where the time maintained
for the IEC protocol is copied. This time is updated when ever a time
synchronization command is received from the host and continually as the
program runs.
2.3.3 Data Link address
Data link address : 1 #Range is 0 to 65535
This parameter defines the data link address for the device emulated on the
module. This address identifies the module on the network along with the
common address of ASDU. Valid values are 0 to 65535.
2.3.4 Data Link address Length
0, 1 or 2
This parameter sets the number of octets used to define the data link address for
the session. A value of 0 is only permitted when balanced mode is used.
