Closed-loop control blocks
6-2 Function Blocks - FM 458-1 DP
Edition 12.2003
Y
Output quantity of the integrator
R=S=H=0 → Y=Yold+X∗NM/DN
(default: 0)
QP
Positive overflow
QP=1 → Y + X ≥ MOD (Y=Y-MOD)
(default: 0)
QN
Negative overflow
QN=1 → Y+X < 0 (Y=Y+MOD)
(default: 0)
YF
Error status of the block
YF=0 no error, YF > 0 coded error output
(default: 0)
The error status is output in a coded form at output YF of the modulo
integrator INT_M. The last error event is always displayed.
