0 to ? - demand reset – Counts upward and is reset when RESET_IN
or OP_CMD_INT transitions to True.
0 to ? - periodic & demand reset – Counts upward and is reset
periodically or by RESET_IN.
Trip and Pre-trip Action When the integration value reaches SP – PRE_TRIP (or 0 – PRE_TRIP,
depending on the INTEG_TYPE), OUT_PTRIP is set. When the
integration value reaches the trip target value (SP or 0), OUT_TRIP is
set. OUT_PTRIP remains set until SP or 0 is reached.
Integration Carryover When the 0 to SP - auto reset at SP or the SPto0-autoresetatSP
integration type is set, you can enable the Carry integration option to
carry the excess past the trip point into the next integration cycle as the
initial value of the integrator.
Modes The Integrator function block supports the following modes:
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.
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.
