Modbus protocol
number

0 to 65535
A Modbus protocol may be
selected by entering the data
protocol ID here. If an unknown
data protocol ID is configured
here, nothing will be transmitted.
Possible data protocol IDs
(existing protocols) are listed in
this Technical Manual.
Instead of a Woodward protocol, a
customer specific data protocol
can be selected. Such a protocol
must have been uploaded onto
the device and its file name must
fit the reserved range from
protocol number 65100 to 65199.
Use Woodward "TelegramMapper"
PC software to create your own
Data Telegrams (refer to
“6.5.4 Modbus Telegram Mapper
(Customer Written Data
Protocols)”
).
Notes
Another protocol can be used after
a reboot of the control:
Change Modbus protocol number
first, then reboot
!

implemented: no separate scp-file
(e.g. "5010.scp") needed.
