Setting up Terminal Communications
In the Terminal Communications tab you can set the driver
parameters.
Setting the Driver Parameters
You must configure the driver parameters to correspond with the
communication settings of the device to which the PanelView
terminal is most immediately connected (whether a controller,
modem, BM85 module, or other Modbus device).
" Fill in the fields in the Driver section of the Configure
Communication Setup dialog box as follows:
Baud Rate
Specify the data-transfer rate between the PanelView terminal and
the device to which it is connected. The default setting is 9600.
Parity
Specify None, Even, or Odd for the type of error-checking to be
used. The default setting is Even.
Flow Control
Specify Hardware or None to determine whether handshaking is
used for data transfer between the PanelView terminal and the
device to which it is connected. The default setting is None.
Note: Hardware flow control must be used with line drivers or
modems.
Stop Bits
Specify the number of stop bits used to signal the end of a data
packet transferred between the PanelView terminal and the device
to which it is connected. The default setting is 1.
Note: The number of data bits is fixed at 8.
A node is a device connected to the Modbus network. When you
configure nodes, you specify a name, device type, and station
address for each device the application will communicate with. A
device at a Modbus station is referred to throughout a PanelView
application by its node name.
You should already have determined the station address for each
node when you completed the Modbus Communications Worksheet.
If not, see Chapter 2, “Planning an Application for Modbus,” for
details about determining station addresses.
