Instruction Manual
CLOCK_PER
: Establishes the period for periodic reset, in
hours.
PRE_TRIP
: Adjusts the amount of mass, volume or energy
that should set OUT_PTRIP when the integration reaches
(TOTAL_SP-PRE_TRIP) when counting up of PRE_TRIP
when counting down.
N_RESET
: Counts the number of resets. It cannot be
written or reset.
PCT_INC
: Indicates the percentage of inputs with “good”
status compared to the ones with “bad” or “uncertain” and
“bad” status.
GOOD_LIMIT
: Sets the limit for PCT_INC. OUT.
Receives the status “Good” is PCT_INCL
≥
GOOD_LIM.
UNCERTAIN_LIMIT
: Sets the limit for PCT_INC.
OUT receives the status “uncertain” if PECT_INC
≥
UNCERT.LIM.
OP_CMD_INT
: Operator command RESET Resets the
totalizer
OUTAGE_LIMIT
: The maximum tolerated duration for
power failure
RESET_CONFIRM
: Momentary discrete value with can
be written by a host to enable further resets, if the option
“Confirm reset” in INTEG_OPTIONS is chosen.
UPDATE_EVT
: This alert is generated by any changes to
the static data.
BLOCK_ALM
: Used for all configuration, hardware, con-
nection failure, or system problems in the block.
BLOCK_ERR_DESC
: Reports more specific details regard-
ing some errors reported through BLOCK_ERR.

Arithmetic Block (AR)
The Arithmetic function block provides the ability to con-
figure a range extension function for a primary input and
applies the nine different arithmetic types as compensation
to or augmentation of the range extended input.
The nine arithmetic functions are:
• Flow Compensation Linear
• Flow Compensation Square Root
• Flow Compensation Approximate
• Btu Flow
• Traditional Multiply and Divide
