■Output type (1)
The output type is determined by the combination of control mode (MODE) and operation type (TYPE) as follows.
Control mode (MODE)
MAN, CMB, CMV, LCM, LCA, LCC
AUT, CAB
CAS, CCB, CSV
■Loop stop processing (2)
The following processing is performed according to the SPA status of the alarm detection (ALM).
SPA status
1
0
■SV count-up processing (3)
SV count-up is performed every execution cycle (T) according to the following expression.
SV'=SV+T
■MVPGS operation (4)
MV operation is shown below.

*1 If the MHI or ERRI of the disable alarm detection (INH) is set to 1, the output upper limit alarm (BB2) and the MHA of the alarm detection
(ALM) are set to 0.
*2 If the MLI or ERRI of the disable alarm detection (INH) is set to 1, the output lower limit alarm (BB3) and the MLA of the alarm detection
(ALM) are set to 0.

11.3 Control Operation Instructions
Processing details
The loop stops.
When the loop stops or the number of operation constant break points is 0, the following operations are performed and the S.PGS
instruction ends.
• The output value (BW) is held.
• All of the output alarm bits (BB1, BB2, and BB3) are set to 0.
• The MHA and MLA of alarm detection (ALM) are set to 0.
• The control mode (MODE) is set to MAN.
The loop runs. When the loop runs, "SV count-up processing (3)" is performed.
