The WebAccess SCADA Node provides a serial interface to the Sharp New
Satellite JW10 Programmable PLC using the Computer Link.

Wiring and Cabling
There are two physical types of connections to the Sharp JW10:
1.
MMI Port
(this is the method tested for this manual).
2.
2-wire RS-422 Communication Terminals
. This method was not
tested for this manual.
Please refer to the Manufacturer’s Documentation for a description of wiring
and cabling.
1.1.1.1
MMI Port
The
MMI Port
is a 9-pin port of the front of the PLC. This is the method
tested for this manual.
This is a one-to-one Link (one PLC per com port).
This Guide was tested using a 9-pin to 9-pin cable labeled JW10/TP02 PC.
The Sharp User’s Manual describes a cable from Sharp (model JW-12KC).
This
is a 9 pin to 25-pin cable.
1.1.1.2
2-wire Communications Port
The Computer Link can also be via the
Communication Port
. This is a two
wire, RS-422A connection on the Lower terminals of the Model JW-1642K
PLC
.
This is a multiple drop link (up to 63 PLCs per comport). This method
was not tested for this manual.
The Lower Terminals of the JW-1624K used for 2-wire RS-422 are labeled
L1
,
L2
and
SHLD
. Shielded twisted pair is required.
