Name Description
Reply end Defines the maximum duration of IEC-101 slave response in
timeout seconds.
Retry limit Defines the number of retries sent to a IEC-101 slave in case of
no reply. If no reply is still received the device closes the
IEC-101 and IEC-104 connections.
Cause of Defines the length of IEC-101 cause of transmission ASDU
transmission header field in bytes. The IEC-101 standard defines value 1.
length
Common Defines the length of the IEC-101 common address ASDU
address header field in bytes. The IEC-101 standard defines value 2.
length
Info object Defines the length of IEC-101 information object address ASDU
address header field in bytes. The IEC-101 standard defines value 2.
length
ASDU The ASDU converter can be used to convert ASDU header field
Converter lengths between IEC-101 and IEC-104 protocols.
Use ASDU This defines if the ASDU header level conversion between
converter 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.
Use ASDU The ASDU type replace function can be used to convert an
type replacer ASDU type (Original type) to another (Applied type) type e.g. in
cases when the IEC implementation differs between master and
slaves.
IEC-101 The original ASDU type searched by ASDU type replacer.
ASDU type
IEC-104 The new ASDU type is replaced by the original type.
ASDU type
Convert short Defines if 56-bit timestamps are converted to 24-bit.
IEC-101 time
stamps
Packet The packet collector can be used to collect many IEC-101
collector 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 Determines if the packet collector is in use.
collector
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.
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.
