INT block modes

The Integrator function block supports the following modes:
•
•
•
The integrator initializes with the value in OUT when the mode changes from Manual to
Automatic. The Manual, Automatic, and Out of Service modes may be configured as
permitted modes for operator entry.

INT block errors

The following conditions are reported in the BLOCK_ERR parameter:

C.3.5

INT block status handling

The output status calculation is based on the accumulation of input statuses. The
calculation includes the accumulations for both input channels when IN_2 is enabled.
Each time the function block executes, the input status is accumulated as Good or Bad as
per the input status. The input as uncertain is considered as Bad input.
The output status is determined with the following logic:
•
•
•
The input status accumulation is reset when the integrator is reset.
Configuration and Use Manual
SRTOTAL: The read-only snapshot of RTOTAL just before a reset. Same units as OUT.
N_RESET: Counts the number of resets. It can not be written or reset.
Manual (Man) – The integration calculations are not performed. OUT, OUT_TRIP,
and OUT_PTRIP may be set manually.
Automatic (Auto) – The integration algorithm is performed and the result is written
to OUT. Reset actions depend on the integration type attribute (INTEG_TYPE) and
the inputs.
Out of Service (O/S) – The block does not execute. OUT status is set to Bad: Out of
Service. The BLOCK_ERR attribute shows Out of service.
Block Configuration Error: INTEG_TYPE is still zero, TIME_UNITn is still zero.
Out-of-Service: The actual mode is out of service (OOS).
When less than 25% of the input status accumulation is Good, OUT status is set to
Bad.
When 25% to less than 50% of the input status accumulation is Good, OUT status is
set to Uncertain.
When 50% or more of the input status accumulation is Good, OUT status is set to
Good.
