6. EXPLANATION OF BASIC ITEMS
This chapter describes basic TR (Transducer
block), AI, and DI function block parameter setting,
displays of the integral indicator. For detailes of the
function blocks, read APPENDIX.
This chapter contains information on how to adapt
the function and performance of the digitalYEWFLO
to suit specic applications. Because two or more
devices are connected to F
OUNDATION Fieldbus,
settings including the requirements of all devices
need to be determined. Practically, the following
steps must be taken.
The following section describes each step of the
procedure in the order given. Using a dedicated
conguration tool allows the procedure to be
signicantly simplied. This section describes the
procedure which has relatively simple functions.
6.1 Setting and Changing
Parameters for the Whole
Process
IMPORTANT
Do not turn off the power immediately after
setting. When the parameters are saved to the
EEPROM, the redundant processing is executed
for an improvement of reliability. If the power
is turned off within 60 seconds after setting is
made, the modied parameters are not saved
and the setting may return to the original values.
Block mode
Many parameters require a change of the block
mode of the function block to O/S (Out of Service)
when their data is changed. To change the block
mode of the function block, its MODE_BLK needs
to be changed. The MODE_BLK is comprised of
four sub-parameters below.
(1) Target (Target mode):
Sets the operating condition of the block.
(2) Actual (Actual mode):
Indicates the current operating condition.
(3) Permit (Permitted mode):
Indicates the operating condition that the block
is allowed to take.
(4) Normal (Normal mode):
Indicates the operating condition that the block
will usually take.
