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.
DH485
IBMPC or compatible with
1784KR, DH485 PC Interface
1747AIC
Isolated Link Coupler
SLC 500
Fixed I/O Controller
1784KR 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.
