Set Data
Processing contents
(1) Mode judgment
Either of the following processings is performed depending on the operation mode (MODE).
(a) When the operation mode (MODE) is any of MAN, CMB, CMV and LCM (alarm clear processing)
1) MHA, MLA and DMLA of the alarm detection (ALM) are turned to 0.
2) BB1 to BB4 of BB are turned to 0.
3) "(3) Output conversion processing" is performed and the S.OUT2 instruction is terminated.
(b) When the operation mode (MODE) is any of AUT, CAB, CAS, CCB, CSV, LCA and LCC, "(2) Change rate, upper/
lower limiter" is performed.
However, when SEA of the alarm detection (ALM) is 1 and SM1501 is ON (with hold), BB1 to BB4 are turned to 0
and the S.OUT2 instruction is terminated.
(2) Change rate, upper/lower limiter
The change rate and upper/lower limits are checked for the input value (E1), and the data after the limiter processing and
an alarm are output.
(a) The change rate limiter performs the following operation and outputs the result of the operation to BB4 and DMLA.
Condition
|E1 - MV|  DML
(E1 - MV) > DML
(E1 - MV) < - DML
*1 When DMLI or ERRI in the alarm detection inhibition (INH) is set to 1, DMLA and BB4 show 0 since the alarm is prohibited.
(b) The upper/lower limiter performs the following operation and outputs the result of the operation to BB2, BB3, MHA
and MLA.
Condition
T1 > MH
T1 < ML
ML  T1  MH
*2 When MHI or ERRI in the alarm detection inhibition (INH) is set to 1, MHA and BB2 show 0 since the alarm is prohibited.
*3 When MLI or ERRI in the alarm detection inhibition (INH) is set to 1, MLA and BB3 show 0 since the alarm is prohibited.
(3) Output conversion
In the output conversion, the output value is calculated from the following formula.
