AB 1746-BAS SLC BASIC Language Module

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.. 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.
