IFC090-FF Block Description
Access
Description
INTEG_TYPE defines the type of counting (up or down) and the type of
R/W
resetting the totalization. The following types are available:
Up auto
Up demand
Down auto
Down demand
Periodic
Demand

normal modes of the Integrator Block. By writing a permitted value to the
target field, you can control the execution modes of the block. The following
block modes are allowed for the IFC090-FF Integrator Block:
Automatic Mode (AUTO)
In this mode, the Integrator Block performs its functional computations in
accordance with its configuration automatically. Totalization is active.
Manual (MAN)
In difference to AUTO mode, the block doesn't perform an automatic
totalization, but freezes the totalization value to the last one obtained in
Auto mode. The OUT status limits switches to constant. In this mode it is
possible to write to the OUT value an arbitrary value to test blocks that
use this OUT value as input.
Out of Service (OOS)
In this mode, the Integrator Block stops its execution. No totalization is
performed,
(Bad:OutOfService:NotLimited).
Counts the number of totalization resets. The counter provides verification
R
that the totalization don't has been reset since it was last checked.
Setting this parameter to reset performs a totalization reset according to the
R/W
chosen integration type (see parameter INTEG_TYPE for details).
see also: INTEG_TYPE
The totalization value and status calculated as a result of executing the block.
R/W
In Auto mode of this block, the value and its status is automatically calculated
on the base of the calculation methods of the Integrator Block. In Man mode it
is possible to write to this value to specify a known, given value that can be
used to test the correct operation of other downstream function blocks.
Totalization starts with 0.0 and counts up with
automatic reset if TOTAL_SP is reached.
Totalization starts with 0.0 and counts up. A reset
isn't performed except either a reset is initiated by
RESET_IN or OP_CMD_INT.
Totalization starts with TOTAL_SP and counts
down with automatic reset if 0.0 is reached.
Totalization starts with TOTAL_SP and counts
down. A reset isn't performed except a reset is
initiated either by RESET_IN or OP_CMD_INT.
Totalization starts with 0.0 and counts up. A
automatic reset is performed in accordance to the
time given in parameter CLOCK_PER (NOTE:
RESET_IN and OP_CMD_INT resets are disabled
and would produce a 'Wrong Mode For Request'
error).
Totalization starts with 0.0 and counts up. To
perform a reset, the operator has to write 'reset' to
parameter OP_CMD_INT.
Same as 'Periodic' with the exception that
RESET_IN and OP_CMD_INT resets are possible.
