Communications
1.1
Summary: JW10 Device Driver
The WebAccess SCADA Node provides a serial interface to the Sharp New
Satellite JW10 Programmable PLC using the Computer Link.
1.1.1 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.
1.1.2 PLC Settings
1.1.2.1
MMI Port
The default settings (memory #226 = 00000000) are:
Data Length = 7 bits
Stop Bits = 1
Parity = None
Transfer Rate = 19200
PLC Address = 01
When using the computer link mode of the MMI Port, the following system
memory settings are used to set Data Length, Stop Bit, Parity and Transfer
Rate.

System Memory Number: #226
Description: Transfer specifications
Format: D7,0,D5,D4,D3,D2,D1,D0
D7=Data Length:
D7=0= 7 bits;
D7=1= 8 Bits
D5=Stop Bits:
D5=0=1 bit;
D5=1=2 bits
D4,D3= Parity:
0,0 = None
0,1 = Odd
1,0 = Even
1,1 = Disabled
D2, D1, D0 = Transfer Rate (Bits / sec):
1,1,1 = 38400
0,0,0 = 19200
0,0,1 = 9600
0,1,0 = 4800
0,1,1 = 2400
1,0,0 = 1200
1,0,1 = 600
1,1,0 = 300
Since only one-to-one communications via the MMI port, the PLC address is
01.
The settings tested for this Device Driver Guide where the default:
Data Length = 7 bits
Stop Bits = 1
Parity = None
Transfer Rate = 19200
1.1.2.2
2-wire Communications Port
The JW10 has a two-wire Communications port for using the computer link,
data link or remote IO. This function is determined by system memory #234:
#234 = 0 = Computer Link Mode (required by WebAccess)
#234 = 1 = Data Link
#234 = 2 = Remote I/O Link.
System Memory #236 sets the Transfer specification for the 2-wire
Communications Port.
The default settings (memory #236 = 00000000) are:
Data Length = 7 bits
Stop Bits = 1
Parity = None
Transfer Rate = 19200
PLC Address = 01
System Memory Number: #236
Description: Transfer specifications
