Name Description Value range
Cause of
transmission
length
Defines the length of IEC-101 cause of transmission ASDU header
field in bytes. The IEC-101 standard defines value 1.
1, 2, 3
Common
address length
Defines the length of the IEC-101 common address ASDU header
field in bytes. The IEC-101 standard defines value 2.
1, 2, 3
Info object
address length
Defines the length of IEC-101 information object address ASDU
header field in bytes. The IEC-101 standard defines value 2.

ASDU
Converter
The ASDU converter can be used to convert ASDU header field
lengths between IEC-101 and IEC-104 protocols.
Use ASDU
converter
This defines if the ASDU header level conversion between
IEC-101 and IEC-104 is performed. If enabled the ASDU header
field lengths are converted between IEC-104 and IEC-101. This
parameter must be enabled if the ASDU header lengths differ
between the IEC-104 and the IEC-101. The information on the field
must fit in the shorter one of the two. It’s not possible to convert e.g.
value 12000 to a one byte field.
No, Yes
Use ASDU
type replacer
The ASDU type replace function can be used to convert an ASDU
type (Original type) to another (Applied type) type e.g. in cases
when the IEC implementation differs between master and slaves.
No, Yes
IEC-101
ASDU type
The original ASDU type searched by ASDU type replacer. 0...255
IEC-104
ASDU type
The new ASDU type is replaced by the original type. 0...255
Convert short
IEC-101 time
stamps
Defines if 56-bit timestamps are converted to 24-bit.
No, Yes
Packet
collector
The packet collector can be used to collect many IEC-101
messages and events to a single network packet instead of
sending every message separately. This function is useful for slow
packet switched communication network (for example Mobitex) for
speeding up especially the general interrogation response.
Use packet
collector
Determines if the packet collector is in use. No, Yes
Max bytes Max bytes defines the maximum bytes trigger for packet collector.
Before a new packet is inserted into the packet collector buffer the
amount of bytes is checked. If the insertion of the new packet
would cause the number of bytes in the packet collector to exceed
MAX BYTES, the old content is sent to the network before inserting
the new one. The value should be smaller than the MTU/MRU of
network used.
1...1500
Max time Max time defines the maximum collect time trigger for packet
collector in 0.1 second increments for packet collector. If there has
been data on packet collector over MAX TIME, the data is sent to
network. The value must be smaller than t1.
1...255
Max packets Max packets defines the maximum amount of IEC-101 packets
stored into the packet collector before sending the data to the
network.
1...255
Other settings
Write syslog Write syslog defines if the error messages are stored to system log
file or not. The system log is available by using Web user interface.
No, Yes
