S.IN
(3) Engineering value reverse conversion
The result (T1) of the input limiter is converted reversely from the engineering value according to the following
expression.
T2 (EMAX EMIN)
(4) Digital filter
The input value (E1) is digitally filtered according to the following expression.
The digital filter is used to reduce noise.
BW=T2 + × (Previous BW value - T2)
(5) Loop stop processing
(a) Setting 1 in SPA of the alarm detection (ALM) selects a loop stop.
A loop stop performs the following processing and terminates the S.IN instruction.
1) BW retains the last value.
2) SEA of the alarm detection (ALM) are turned to 0.
3) The operation mode (MODE) is changed to MAN.
4) BB1 to BB3 of BB are turned to 0.
(b) Setting 0 in SPA of the alarm detection (ALM) selects a loop run.
A loop run performs "(1) Range check".
Operation Error
In the following cases, the error flag (SM0) turns ON and the error code is stored in SD0.

When an operation error occurs
When the values of
