4.8 Integrator Block (IT)
The following tables list the 2 Integrator Block parameters in alphabetical order.
It describes characteristics of the signal converter measurements for forward (positive) and
reverse (negative) flow at the same time. Both integrators were intended to totalize the forward
flow Integrator 1 (+ Flow Totalizer) on the one hand and the reverse flow Integrator 2 (- Flow
Totalizer) on the other. The configuration of these blocks is almost the same, unless stated
differently.
The following tables contain short parameter description, factory settings (Initial Value (IV)) and
possible settings.

R
This parameter reflects the error status associated with the
hardware or software components associated with a block. It
is a bit string, so that multiple errors may be shown.

By setting this parameter to an allowed value (one of the value
from permitted modes) user can change the block execution
mode. Changing of modes is required to change the access
permissions available to various parameters.

R
This is the current mode of the block, which may differ from
the target based on operating conditions. Its value is
calculated as part of block execution.
