Problem or Question:

of the IP RTU using soft
switches in LocalView,
but I forgot to write it
down, and now I can't
remember what it was. I
can't get back in to read
it because I need the
local address to start
communications? What
do I do now?"
FOR OPEN BSI 3.0 (or
newer) ONLY:
"I made some changes to
certain parameters in
'RTU Configure' mode
(using LocalView) but
they aren't reflected in
my running RTU. How
come?"
"Open BSI
communicates with the
RTUs via radios. Open
BSI seems to be able to
send messages, but the
RTUs don't answer."
DOS-BASED TOOLS:
"I get the message
'Communications
cannot be established
for ACCOL TOOLS
functionality.' What
does this mean?"
"I get the message
'Timeout this
transmission'. What
does this mean?"

Cause and/or Suggested Remedy:

position. When the default switch is OFF, the unit
will use whatever local address is defined via the
hardware switches (SW2). You can use the
address specified by SW2 to establish
communication, and then view whatever
information you previously entered for soft
switches. NOTE: When the default switch is used
in this way, the communication ports default to
BSAP 9600 baud.
The changes you enter in "RTU Configure" mode
are stored in FLASH memory but they are NOT
activated until the RTU has either been re-
downloaded with a new ACCOL load, or the unit
has been reset by pressing the reset switch. Reset
the unit (or re-download it) and the changes will
become active.
There could be many reasons for this. One possible
problem, however, could be that the port in
Windows 95 is truncating the messages. See
'Configuration Issues For Radios' in 'Chapter 4'
for information on how to correct this particular
problem.
(UOI, TOOLKIT, on-line AIC, TASKSPY, DIAG)
There are several possible reasons for not being
able to communicate, including:
Incorrect port setup, incorrect baud rate, bad
cable, the node address was specified incorrectly.
Go to the Reconfigure Communications Setup
Menu and change entries as necessary.
This means that the PC running the tools (UOI,
Toolkit, etc.) has received no transmissions from
the slave node (controller) connected to it, for at
least 3 times the "Timeout" value specified on the
Define Local Link portion of the Communication
Setup Menus. If you are in the process of
establishing communications when this occurs,
there is probably a data link or network routing
