Processing details
■Analog memory processing
This function block increases or decreases values at a fixed rate and outputs the result from the output variable OUT_.
Output (OUT_)
Output high value (d1_)
Output setting value (SETV)
Output low value (d2_)
Mode switching (Mode)
Output addition (INC_)
Output subtraction (DEC_)
Condition
Mode switching
(MODE)
FALSE (MANUAL)
TRUE (AUTO)
MODE: Mode switching
OUT_: Output value
INC_: Output addition signal
DEC_: Output subtraction signal
INCV: Output addition value
DECV: Output subtraction value
SETV: Output setting value
d1_: Output high limit value
d2_: Output low limit value
T: Execution cycle
Operation error
Error code Description
(SD0)
3402H Input data (MODE, INC_, DEC_, INCV, DECV, or SETV) or operation constant (d1_, d2_) is a subnormal number or NaN (not a number).
3403H An overflow has occurred.

Output (OUT_)
OUT_ = SETV
OUT_ = OUT_ + |INCV|  T
When OUT_ is more than d1_, OUT_ equals to d1_.
OUT_ = OUT_ - |DECV|  T
When OUT_ is less than d2_, OUT_ equals to d2_.
OUT_ = OUT_
