Local Port
The Local port settings determine the serial port, data rate, and phone
number (if any) to be used in a direct connect setup. Because the Local
port protocol does not include address information, this option is limited
to only one (1) PLC per serial port.
Unilink Host Adapter
If Unilink Host Adapter is selected, you must specify the Serial port to
be used and the NIM (Network Interface Module) address as set at the
PLC. You also should configure several settings on the Unilink Host
Adapter by selecting the Configure UHA… button.
The settings in this dialog box are globally applied to all PLCs on the
specified TIWAY network (each network requires a separate serial port).
Therefore, it is only necessary to configure each Unilink Host Adapter one
time—you need not repeat this step every time you create a new Tiway
object.
Data rate specifies the communication speed between the computer and
the Unilink Host Adapter. It also determines the required dip switch
settings on the UHA for the selected baud rate.
The Host Adapter Operating Mode determines if the Unilink Host
Adapter is the network manager (Master Host Interface Unit) or just
another network secondary (Host Interface Unit). There must be exactly
one MHIU per TIWAY network.
