36 Select SLC 500 I/O Modules
BASIC Language Modules
The BASIC modules add data collection and report generation capability to any SLC
system. Two configurable channels enable you to connect to printers, operator interface
terminals, modems, and other foreign devices.
The 1746-BAS-T module is a higher-speed version of the 1746-BAS module with
identical hardware features. The modules can be interchanged, except that the 1746-
BAS-T module uses different (optional) memory modules.
The modules program in the BASIC language using an ASCII terminal or 1747-PBASE
programming software. Because the 1746-BAS-T module can execute a BASIC program
four times faster than the 1746-BAS module, programs written originally for the
1746-BAS module may require adjustment for identical operation on a 1746-BAST
module.
