RS-232 Communication Interface 203
SLC 500 Devices that
Support RS-232
Communication The SLC 500 product line has two other modules, aside from the SLC 5/03,
SLC 5/04, and SLC 5/05 processors, that support the RS-232 communication
interface. They are the 1746-BAS BASIC module and the 1747-KE
DH-485/RS-232C interface. Both of these modules can be used with either
the SLC 5/01 or SLC 5/02 processor.
1747-KE Module
The 1747-KE module is a communication interface module that acts as a
bridge between DH-485 networks and devices requiring DF1 protocol. You
can configure the DF1 port on the 1747-KE module for RS-232/423, RS-422,
or RS-485 devices. Residing in an SLC 500 chassis, the 1747-KE module is
ideally used as an interface module, linking remote DH-485 networks via a
modem to a central host.
For more information on the 1747-KE module, see the DH-485/RS-232
Interface Module User Manual, publication 1747-IN006.
1746-BAS and 1746-BAS-T Modules
The 1746-BAS and 1746-BAS-T modules, which are programmed using the
BASIC language, have two configurable serial ports for interfacing to
computers, modems, serial printers, and other RS-232 compatible devices.
You can also use them for off-loading complex math routines from an SLC
500 processor, thereby conserving ladder logic memory.
For more information on the 1746-BAS module, see the SLC 500 BASIC and
BASIC-T Module User Manual, publication 1746-UM004.
