Communication Setup
Dialog box parameters
Serial Port
Select this option if the communication will go over the serial port and specify the port and
data speed below.
Communication Port
Specify the serial port over which the ToolBox will communicate with the RTU.
Data Speed
Specify the data speed at which the ToolBox will communicate with the RTU.
Protect Third Party Protocol over MDLC port
The 'Protect Third Party Protocol over MDLC port' checkbox ( V7.50) is relevant only
when a ToolBox MDLC port is also used for some Third Party protocol. If this Third
Party protocol is not sophisticated enough to ignore messages from other protocols sharing
the port, the Communication Setup utility allows you to block all messages not intended
for that protocol for the length of the session.
Before each MDLC session, MDLC sends a 'start protection' message, after which the
remote prevents MDLC messages from being sent to Third Party protocol. At the end of
the session, an 'end protection' is sent which opens the port to all MDLC messages. If
communication fails and the 'end protection' transmission is lost, protection will end after
a few minutes, as determined by an internal timer.
Third Party protocol protection adds overhead of approximately 20 bytes/session (start/end
protection bytes) and therefore should not be selected if the port is only used for MDLC.
Mature protocols such as MDLC and DNP do not require this protection and can recognize
and reject messages which are irrelevant to them.
Ethernet Port
Select this option if the communication will go over an Ethernet connection and specify
the IP address below. A MOSCAD/MOSCAD-L RTU or IP Gateway with connectivity to
Ethernet must act as a bridge to the Ethernet for other RTUs in the field with no such
connectivity.
Local Site IP Address
If the communication is over an Ethernet connection, specify the IP Address of the IP
Gateway. Range: 000.000.000.001-255.255.255.254
IP port number
Range: <1-65535> Default: 2002
If the communication is over an Ethernet connection, specify the IP Port Number of the IP
Gateway. This number is common to all RTUs and IP Gateways connected to the link.
Cancel
If you press the Cancel button, the Communication Setup window will close.
OK
The OK button saves changes made to the Communication Setup. A message will appear
reminding you to close any ToolBox applications and Stop the Communication Driver in
order for the changes to take place. Once all other ToolBox applications are closed and the
driver has been stopped, click the Apply button to apply changes. If you press the OK
button, the Communication Setup window will close.
