The BASIC development software provides the user with a structured

and efficient means to create BASIC programs for the module. This

software is loaded into a an MS-DOS compatible personal computer. It

uses the personal computer to www.abb-drive.com facilitate editing, compiling

(translating), uploading, and downloading of BASIC programs.

The BASIC development software has a menu-driven, window-type

environment that offers:

• pull-down menus to access all editor functions.

• function key access to frequently used functions.

• multiple window editing.

• cut and paste support between windows.

• search and replace support.

• search between files support.

• built-in calculator that can paste results into your program.

• ASCII look-up table.

• line draw editor to create operator interface images without having to enter ASCII characters.

• keystroke macros.

• undo and redo functions.

• extensive help messages for each menu, menu option, and for keywords embedded in the menu text.

• capability to create user-defined macro libraries.

• sophisticated debug tools including watch windows, single-step

operation, and go to cursor breakpoint operation.

• syntax checked translations to native BASIC to reduce debug time.

• BASIC translator that steps through the BASIC program and identifies errors.

• ASCII terminal mode.

• hex file transfer support.

The development software enables you to program the module from a

personal computer connected to either the module’s DH485 or PRT1

ports. The software allows direct access to the module through

terminal emulation over an RS-232/423 or DH485 network.

Refer to the BASIC Development Software Programming Manual,

publication 1746-PM001, for additional information on the software.

Typical Configurations

The typical configuration of the SLC system that incorporates your

BASIC or BASIC-T module depends on whether the module is:

• integrated with a SLC 500 fixed or modular controller.

• programmed directly with an ASCII terminal or programmed

using a personal computer with the BASIC development

software, 1747-PBASE.

• communicating with a DH485 network or with an external

source through a modem using DF1 protocol.
