1730 has the MODBUS option, it must be configured to use the ULTRAc protocol so that it
will pass all messages received from RTUs through to the Communications And I/O Test
program.
When connected to the Model 1732 RTU, you will be able to test only the I/O points on that
particular RTU.
All functions of the program are accessed through the menus. The center of the main window
is where messages received from the controller and/or RTUs are displayed. The bottom of
the window shows the currently selected device type and address, and the communications
port settings.
SETTING OPTIONS
Selecting Options from the main menu brings up the dialog shown in Figure 10.
In the Address field, put the address of the Controller or RTU that you want to test.
The Device field should specify the type of device you are testing. The choices include:
1730, 1732, 1708, and 1716.
Figure 10. The Options Dialog Box
The Comm port, Baud rate and Format fields select and configure the RS232
communications port used to communicate with the device under test. You must select a port
that is not in use by any other program.
The Acknowledge exceptions field should be checked if you want the test program to
acknowledge exceptions reports received from the Model 1730 Controller and/or RTUs. If
not acknowledged, the sender of the exception will keep sending the report, and eventually
go into its communications fail state.
The Show exceptions field controls whether or not exception reports are shown on the
screen. When this box is checked, exceptions reports received from any device will be
displayed.
