Function Codes – Introduction
M 8 MICRO-SCAN. Reset response is turned on and is operating with MICRO-
SCAN algorithm. It can be used with either externally generated adaptive gain or
reset, but not with external feedback. Manual reset must be turned off.
The Standard Algorithm and Microscan Algorithm have different antireset windup
characteristics that affect how they approach limits. Otherwise, the two algorithms
integrate the same. Standard is necessary on applications requiring external feedback
and where better management of blips is required.
Microscan comes out of a limit one reset time constant ahead of the setpoint/process
crossover and is required on applications needing good startup characteristics without
overshooting and on applications with large setpoint changes which also require an
approach to the new setpoint without overshooting.
Pre-Act (column 3):
O 0 Off. Pre-Act response is turned off.
P 16 On Process. Pre-Act response value is determined by process signal.
E 32 On Error. Pre-Act response value is determined by error signal.
Manual Reset (column 4):
O 0 Off. Manual reset response is turned off.
E 64 Enabled. Manual reset response is turned on (only if reset response is turned
off).
