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.

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

1,0,0 = 1200
1,0,1 = 600
1,1,0 = 300
System Memory #237 sets the PLC Address: 001 to 077 (octal).
WebAccess would use decimal addresses: 1 to 63 (decimal).
2. WebAccess: Parameters
WebAccess drivers provide object-oriented "parameters" to guide novice
users with pre-built templates containing typical addresses and provide a
productivity tool for experienced users. Users can select a parameter type to
start, and then modify the address to the correct register in order to build a
tag.
Note 1 –WebAccess cannot write reliably to a Register if Ladder Logic is also
writing to the same register. Ladder Logic executes more quickly that
WebAccess and will overwrite any write from WebAccess.
Note 2 –The PLC must be in RUN mode for physical IO to be scanned by the
PLC and written to memory of PLC.

Version 6.0 rev 0 Advantech Corp., Ltd. page 7
Figure 3.1 Serial Comport properties for Sharp JW –MMI Port, default settings (Memory
#236 or #226 = 00000000
3.2.1 Comport Number
The Serial Comport requires the comport number to match that of the
physical interface (e.g. COM1, COM2, COM3, etc) on the SCADA Node.
3.2.2 Description
This is an optional field used for user reference.
3.2.3 Baud Rate
For the Sharp JW10, values are from 300 to 38400 baud. The default
setting is 19200.
This must match the baud rate configured in the PLC. Please refer to the
Manufacturer’s Documentation to determine the actual baud rate set in the
PLC.
All PLCs connected to this comport must use the same Baud Rate.

Advantech WebAccess Device Driver Guide Sharp JW 10 Serial
Version 6.0 rev 0 Advantech Corp., Ltd. page 8
3.2.4 Data Bits
For the Sharp JW 10, the values are 7 or 8 Data Bits. The default setting is
7 bits.
This must match the number of data bits configured in the PLC. Please refer
to the Manufacturer’s Documentation to determine the actual number of Data
Bits set in the PLC.
All PLCs connected to this comport must use the same number of data bits. A
typical value is 8 bits.
3.2.5 Stop Bits
For the Sharp JW 10 there can be 1 or 2 Stop Bits. The default setting is 1
stop bit.
This must match the number of stop bits configured in the PLC. Please refer
to the Manufacturer’s Documentation to determine the actual number of Stop
Bits set in the PLC.
All PLCs connected to this comport must use the same number of stop bits.
3.2.6 Parity
For the Sharp JW 10 the Parity can be None, Odd, Even or Disabled.
The default setting is None.
This must match the parity configured in the PLC. Please refer to the
Manufacturer’s Documentation to determine the actual number of Data Bits
set in the PLC.
All PLCs connected to this comport must use the parity.
3.2.7 Scan Time
The Sharp JW 10 was tested with a Scan time = 2 Seconds.
This is the time in milliseconds to scan the PLC. This must match the ability
of the PLC to respond.
If the PLC cannot respond as fast as the SCAN Time entered, WebAccess will
scan at a slower rate.
3.2.8 Timeout
The Sharp JW 10 was tested with Time Out = 200 Milliseconds.
Timeout is the time waited before re-sending a communications packet that
did not have a reply.
Timeout specifies how long the software waits for a response to a data
request, specifically to wait for a reply from one packet. A recommended
value is 7 to 10 ticks, longer if the communication device is slow. This is
protocol dependent: some protocols do not allow changes in time out.
Combined with Retry count, Timeout also determines time to consider a
device or port as BAD. Timeout is the time to wait since last communication
packet sent without a reply. Time is in milliseconds. The slow or poor quality
communications require longer timeout. The faster the communications
network or device, the shorter the timeout required. Shorter timeouts notify
operators of communications failure more quickly.
3.2.9 Retry Count
The Sharp JW 10 was tested with Retry count = 3.
Number of times to retry communications if no reply is received from a
device. Combined with Timeout, also determines time to consider a device or
port as BAD.

Advantech WebAccess Device Driver Guide Sharp JW 10 Serial
Version 6.0 rev 0 Advantech Corp., Ltd. page 9
In addition, Indicates the number of times after the first attempt has failed
that communication should be attempted before indicating a failure.
Specifically, how many times to send a single packet after the field device
fails to respond to the first packet. After the retry count is exceeded, all the
tags in the packet are marked with asterisks and the next packet of requests
is sent. A reasonable value is 3 to 5 times. After this number of tries, the
tags
in this packet are marked as "fail to respond" (i.e. asterisks) and are
disabled.
In reality, increasing the number of retries hides failures on the part of the
field device to respond to a request. Essentially, increasing the retries gives
the field device more chances to reply.
3.2.10 Auto Recover Time
The Sharp JW 10 was tested with Auto Recover Time = 60 Seconds.
Auto Recover Time is the time to wait before attempting to re-establish
communications with a BAD device or port.
If communications to the PLC is unusually slow due to hardware,
communications or network issues, you might consider increasing this value.
If communications to the PLC or RTU fails frequently, you may want to
decrease this number in order to have WebAccess try to re-establish
communications sooner.
If communications to the PLC, RTU or device Fails (i.e. exceeds Timeout)
WebAccess will wait the Auto Recover Time before trying to re-establish
communications.
3.2.11 Hand Shake RTS
The Sharp JW 10 was tested HandShakeRts = Yes.
The RTS (Request To Send) signal is raised and lowered on the Serial
Communications Port if this value set to Yes.. RTS is determined by settings
in the field device. Refer to your device interface manual to determine the
value for this field and the type of cable used.
3.2.12 Hand Shake DTR
The Sharp JW 10 was tested with HandShakeDtr = Yes.
The DTR (Data Terminal Ready) signal raised and lowered on the Serial
Communications Port if this value is set to Yes. DTR is determined by
settings
in the field device and the type of cable used. Please refer to the
Manufacturer’s Documentation to determine if DTR handshake is set in the
PLC.
3.2.13 Backup Port
The Backup Port has not been tested for the Sharp JW10.
