Codes
Function code settings (FCODE’s) determine the internal values for:
l
Tuning Parameters
n
Configurable Options
These values are determined by configuration and should be entered
by the user in the FCODE tables.
Setting and checking of these FCODE’s in the DPRSOO can be carried
out at one time with the instrument in the Programming mode.
The instrument need not be connected to sensors and actuators for
FCODE setting. If, however, setting is to be performed without any
connection to A01, Terminal 9 and 10 must be short-circuited to
prevent an open-circuit error message (ERR 4) from being initiated.
All FCODE’s can be altered during operation, however, to change
configuration options, the controtler must be in the Manual mode.
To set or alter FCODE 101 or higher, the DPRSOO
must be set to the Manual mode. This ensures
that the output signal is under local control and
cannot be provided with an unwanted output
value.
