Rockwell Automation 1771-DB BASIC MODULE - Manual (Page 6)

Preface A
Summary of Changes
SOC-4
Turbo Speed Allows Faster Program Execution
The BASIC module operates up to four times faster than before.
With a C toolkit and C compiler available from one of our Pyramid
Solutions Program partners, you can run C programs on the BASIC
module even faster. See your Allen-Bradley representative for more
details on the C toolkit. You can also run the BASIC module at the same
speed as the Series A module for applications that cannot be run at a faster
speed.
With the BASIC Development Software (1747-PBASE) you can shorten
program development time. This powerful programming tool provides a
high level BASIC programming language, powerful debugger, ASCII
terminal emulator, and a thorough Help system to streamline BASIC
module programming and troubleshooting.
Reset Switch Support
The BASIC module has a hard reset switch located behind the module
ejector tab. When this switch is pressed, the BASIC module initiates a full
reset. The BASIC module reacts to this reset the same as it does when you
turn on power to your I/O chassis backplane.
Enhanced Serial Port Statements and Modifiers
With the BASIC module’s new enhanced serial port statements (EOF,
INPS, INPL) and port statement modifiers (# and @) developing programs
for serial communications is easier. When you use the @ operator you
direct communications to port PRT1. When you use the # statement
modifier you direct communications to port PRT2.

Floating Point Number Support
The Series B module supports PLC-5 floating point numbers; Series A did
not.
