Lost (abort) connection retry time
30 seconds
Is authentication supported
Yes
What is the maximum and minimum MMS PDU
size
Max MMS PDU size 65535
Min MMS PDU size DO(4096)
What is the typical startup time after a power
supply interrupt
The module boot time is approximately 40
seconds. Depending on the size of the RX3i
controller application, the number of drivers,
and link connections for each driver, it will
take an additional 1 to 30 seconds to be fully
functional.

Description
Value / Clarification
Maximum object identification length
The following specifies the limits in “IEC
61860 Configurator”:
LD: 128 chars/octets
LN: 16 chars/octets
DO: 128 chars/octets
DA: 128 chars/octets
FC: 2 chars/octets
The following are limits for PLC Protocol
variables (PPV), which are representation of
IEC 61850 DO/DA in the RX3i controller
project as a variable list. These variables are
automatically generated on selecting IEC
61850 attributes from the Configurator.
LD: 19-26 chars
LN_DO: 32 chars
DA_FC: 29 chars (FC: 2 chars )
Here is the example for variable
representation:
IEC 61850 - Configurator
The IEC 61850 variable as seen in the
Configurator dialogue:
SR350.GEDeviceSR350.GGIO1\Beh\q[ST]
SR350.GEDeviceSR350.MMXU1\A.neut\c
Val.ang.f[MX]
PLC Protocol Variable(s)
The PPV set that gets created automatically in
the RX3i controller project for the above IEC
61850 variable:
S8_SR350_GEDeviceSR350.GGIO1_Beh.q
