FCO770 Users Guide Issue 1
FBUS SETTINGS MENU
The FCO770 can communicate with a computer/PLC using the Fbus protocol. Application
software is available from Furness Controls such as Cmax or the FCS432 Fbus utility. The
fbus protocol is documented separately from this user guide.
Select the Fbus communications port and configure it to match the computer/PLC that the
FCO770 is to be connected to.
PORT
•
Note that a port might not be listed if the optional hardware is not fitted or if the port
is already selected for use in the Printer Settings menu.
•
Options:
o
DISABLED:
Fbus
c
ommunications is not available.
o
RS232:
Uses the 9 way D rear panel connector.
o
USB:
Uses the front panel connector.
o
RS485:
(optional) uses the rear screw terminal connector.
o
LAN
: (optional) uses the local area network connector (LAN1)
I/D NUMBER
•
Assign a unique identification number to this instrument for Fbus communications in
the range 01 to 99.
BAUD
•
The baud rate is the speed that data is sent via the serial ports. The baud rate must be
the same on the FCO770 and device being connected. When using the LAN the baud
rate must match the configuration of the LAN adaptor. This is not used for USB.
•
Options: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.
PARITY
•
Select the number of data bits and type of parity error checking to use when sending
data via the RS232, RS485 and LAN ports. Parity is not used for the USB port.
•
The parity setting must be the same on the FCO770 and device being used. When
using the LAN the parity must match the configuration of the LAN adaptor.
•
Options:
o
8,NONE:
8 data bits and no parity.
o
7,ODD:
7 data bits plus odd parity.
o
7,EVEN:
7 data bit plus even parity.
o
8,ODD:
8 data bits plus odd parity.
o
8,EVEN:
8 data bits plus even parity.
•
Note that extended symbols/characters require 8 data bits. European characters are a
subset of code page 1252. Cyrillic characters are a subset of code page 1251.
•
Generally, 8 data bits with no parity is preferred for use with older instruments that do
not support 8 bits plus parity. Only use 7 data bits when compatibility with older
instruments is necessary and parity is required and you do not use extended
characters.
