Woodward 73
02 LINK ERROR indicates Link Error sets TRUE when the slave fails to answer a data request in
specified number of time-out seconds.
03 ERROR PERCENT
Error Percent outputs reflects communication quality as a percentage by dividing the number of exception
errors detected by the total number of communication transactions. This essentially gives the number of
message/packet errors detected.
04 ERROR NUMBER
Error Number outputs the code number of the communication/exception error that occurred.
Table 3-3. Communication Error Code
CODE NAME MEANING
00 NO ERROR Error free
The following are returned to the master.
01 ILLEGAL
FUNCTION
Message function received is not an allowable action for addressed slave.
(Unsupported or illegal function code).
02 ILLEGAL DATA
ADDRESS
Address referenced in data field is not an allowable address for the
addressed slave location. (Master requested data, which is not configured
from slave).
03 ILLEGAL DATA
VALUE
Amount of data requested from slave was too large for slave to return in a
single response. Woodward maximum is 118 registers.
The following are displayed only.
09 CHECKSUM
ERROR
Error in the checksum. Can indicate link quality and/or noise problems.
10 GARBLED
MESSAGE
Data received by the slave, but it is too short to be a valid Modbus
message/command.
05 BAUD RATE dflt=10 (7, 12)
Set the Baud rate, which defines the transfer rate for port communications.
8=9600
9=19200 10=38400
11=57600 12=115200
06 BAUD RATE IS SET FOR
Shows the selected Baud rate.
07 DATA BITS dflt=2 (1, 2)
Set the Data bits input defines the protocol for the number of data bits in the data packets.
1=7
2=8
08 DATA BITS ARE SET FOR
Shows the selected data bits.
09 STOP BITS dflt=1 (1, 3)
Set the Stop bits, which defines the number of stop bits for the communications protocol. Stop bits specify
the time that elapses between transmitted characters.
1=1 stop bit
2=2 stop bits
3=1.5 stop bits
10 STOP BITS ARE SET FOR
Shows the selected stop bits setting.
11 PARITY dflt=1 (1, 3)
Set the Parity input defines protocol for the parity. If you selected 8 data bits select '1' for none.
1=OFF (none)
