ASDU converter
The ASDU converter can be used to convert the ASDU header field lengths
between the IEC 60870-5-101 and IEC 60870-5-104 protocols.

Use ASDU converter
defines if the ASDU header field length conversion is in use.
This parameter must be enabled if the ASDU header field lengths differ between
IEC 60870-5-101 and IEC 60870-5-104.

Note
The information in the field must fit in the shorter
one of the two. It is not possible to convert, for
example, the value “12000” to a one byte field.
Use ASDU type replacer
can be used to convert an ASDU type (original type) to
another type (applied type), for example, in cases when the IEC implementation
differs between the master and the slaves.
