DATAFLOW RTU

>>> RTU PROGRAMMER VERSION 3.03 HELP FILE <<<(continued)

1.5 Message Line

The third line from the bottom of the RTU system configuration screen is the message

line. This line displays important information about the status of uploads, downloads,

disk reads, and disk writes.

1.6 Function Keys

The last two lines of the RTU system configuration screen form the function key menu.

To perform one of the listed tasks either press the related function key or click the

command with your mouse. Field help will display a short help message for the field

where the cursor is. Full help will display this text file.

Upload will read the contents of the RTU currently connected to the serial programming

cable and display the configuration on the screen. Download will cause the currently

displayed configuration to be written to the RTU. Read disk will get the configuration

stored in the file named in the file name field at the top of the screen and display this

configuration on the screen. Write disk will save the currently displayed configuration to

the file named at the top of the screen.

Selecting I/O CONFIG will display the RTU input/output configuration screen. SCADA

CONFIG will display the RTU SCADA configuration screen. Press F9 to display a list of

.USR files which you can select. F10 will return the program to the main screen.

2.0 RTU Input/Output Configuration Screen:

The input/output screen allows the user to edit the configuration of the RTU connected

to the serial programming cable. Inputs will be sent to any RTU on send list. Outputs are

controlled by the RTU listed under each output number You must also be certain that the

unit which has the input controlling this output has its inputs and send list properly

configured.

2.1 Inputs:

There are six EXTERNAL analog inputs to the RTU. Although these inputs are all analog,

they can be treated as digital by the microprocessor. The battery voltage is a seventh

INTERNAL input to the RTU.

An eight character long name may be used to identify each of the inputs ( i.e.: TANK1LVL,

PUMP2PWR). These tag names will be stored in the configuration files when they are

saved to disk, but they will not be stored in the RTU due to EEPROM space limitations.

All inputs to the RTU are read by the microprocessor as analogs. The microprocessor

converts the input to a value between 0 and 255 (8-bit resolution). Inputs can be treated

as digital inputs by taking their analog value and comparing it to a digital threshold or set

point to determine whether it is a high or low. Digital inputs cause a message to be created

only when they cross the set point in either direction. Analog inputs cause a message to be

created whenever they change from the previously reported value by a certain amount. This

amount is called the dead zone.
