1747-6.2
A configurable communications port on the interface supports
RS-485 and RS-232. Use DH-485 to communicate point-to-point
with the SLC processor or over the network via
Catalog Number 1747-AIC Isolated Link Couplers. The
point-to-point connection allows for faster communication
throughput and less DH-485 network loading.
Monitoring with a DTAM Micro
The DTAM Micro extends the DTAM Plus product line by providing
another operator interface to the SLC 500 family of processors.
DTAM Micro is a low cost operator interface and is physically
smaller than the DTAM Plus. This device features a 2 line x 20
character display window for viewing data table information and
operator prompts. Up to fifty application screens can be stored in
memory.
DTAM Micro is available with either an RS-485 port or an RS-232
port. The RS-232 port is used to communicate point-to-point with
the SLC 5/03. Use the RS-485 port to communicate point-to-point
with the SLC processor or over the DH-485 network via Catalog
1747-AIC Isolated Link Couplers. The point-to-point connection
allows for faster communication throughput and less DH-485
network loading.
Monitoring with a PanelView Operator Terminal
The PanelView Operator Terminals provide operator interface
capabilities in space-saving, flat-panel designs. Offering optimum
viewing angles, these electronic operator interfaces feature pixel
graphics and high-performance functionality in both color and
monochrome displays. The PanelView Operator Terminals allow
you to enter input using function keys or a touch screen.
PanelView Operator Terminals are available in DH-485 and RS-232
versions. With the DH-485 version, you can connect the PanelView
to a single SLC 500 processor or multiple SLC 500 processors on the
DH-485 network. The PanelView Operator Terminal supports
DH-485 point-to-point or network transfers.
With the RS-232 version, you connect directly to channel 0 of an
SLC 5/03, SLC 5/04, or SLC 5/05 processor using DH485 protocol.
This gives you dedicated DH485 connection for high priority data.
The RS-232 channel supports passthru from the DH+ network to the
PanelView 550 through channel 0 of an SLC 5/04 processor.
