About the BASIC and BASIC-T Modules
The BASIC module is a single-slot module that resides in a SLC 500 fixed or
modular controller chassis. The BASIC-T module is a higher speed version of the
BASIC module with identical hardware features, including two configurable serial
ports for RS-232/423, RS-422, and RS-485 communication with I/O devices.
Communication to an SLC 500 controller can take place across the 1746 I/O
backplane or on the DH485 network through the module’s DH485 port. Both
modules also feature 24K bytes of battery-backed RAM, optional 8K or 32K byte
non-volatile memory modules, and multiple LED indicators for operator interface.
The modules can be programmed using an ASCII terminal or a personal computer
equipped with 1747-PBASE BASIC development software
TIP
The 1746-BAS module is compatible with the 1747-M1 and
1747-M2 memory modules.
The 1746-BAS module is also compatible with existing 1747-M3
and 1747-M4 memory modules. The 1747-M3 and 1747-M4
memory modules are no longer available for sale from Rockwell
Automation.
The 1746-BAS-T module is compatible with the 1771-DBMEM1
and 1771-DBMEM2 memory modules.
TIP
Due to the high speed of the 1746-BAS-T module, existing
programs written for the 1746-BAS module may require
adjustment for identical operation using the 1746-BAS-T module.
