Communicating with the SCADA Host

Communication to the flow computer through a SCADA host computer requires you to
configure the host computer software, which varies depending upon whether you are
using OpenEnterprise or another host software package. Much of this configuration is
beyond the scope of this topic, but no matter which host you are using, there are certain
steps you must take:

4.2.2 Communicating with a Laptop Using One of the Serial
Ports
To communicate with a laptop using a serial port:

Decide how the SCADA host should communicate with the flow computer. This
could be through connection with one of the communication ports. A serial port
connection could be a cable directly connected to the SCADA host or there could be
intermediate connections through a radio or modem.
Decide which communication protocol you will use. This could be DNP3, ROC,
Modbus, or BSAP. See these documents for more information:

Provide the SCADA host with information about the various parameters it needs to
extract from the application running in the flow computer. Typically, the SCADA host
software includes a utility that allows you to identify this information so it can be
incorporated into the database at the SCADA host.
Using whatever human-machine interface (HMI) tools exist for the SCADA host,
create graphical displays or reports that include the parameters from the
application required for successful operator interaction (setpoints, flow variables
and so on).
Your laptop must have Field Tools software with FBxConnect software installed.
You must know a valid username/password combination for the flow computer.
If the flow computer is not awake, you must wake it up first. (See
