SLC 500 programmable controllers communicate across an embedded
DH-485 network for program support and monitoring. The following
products provide networking options for the SLC 500 programmable
controllers.
DH485
IBMPC or compatible with
1784KR, DH485 PC Interface
1747AIC
Isolated Link Coupler
SLC 500
Fixed I/O Controller
1784KR Personal Computer Interface Card
The Personal Computer Interface Card provides an interface for IBM XT/AT
and compatible computers to communicate over the Allen-Bradley DH-485
communication network. This includes communication to the Allen-Bradley
line of SLC 500 programmable controllers.
Features Benefits
PC XT/AT Interface to
DH-485
Eliminates the need for the personal
interface converter when using
Advanced Programming Software.
DH-485 isolation Eliminates the need for an isolated
link coupler.
Reduced personal computer
overhead
Provides a faster update time for the
user interface through the
co-processor.
