*1 The data of the item(s) where the values within the recommended range are given in the parentheses are stored by the
system. Users cannot set the data.
*2 The loop tag memory and loop tag past value memory occupy a total of 128 words. (Refer to Page 27, Section 3.3.1 for

When control is to be started from the initial status, the data must be cleared with the sequence program.
(2) Execution cycle ( T)
Set the execution cycle in SD1500 and SD1501 as real numbers.
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) MHA2 and MLA2 of the alarm detection 2 (ALM2) are turned to 0.
3) BB1 to BB4 of BB are turned to 0.
4) The tracking flag (TRKF) of the alarm detection inhibition (INH) is turned to 1.
5) "(5) Output conversion processing" is performed and the instruction is terminated.
(b) When the operation mode (MODE) is any of AUT, CAB, CAS, CCB, CSV, LCA and LCC, "(2) Input addition
processing" 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.OUT1 instruction is terminated.
