11 PROCESS CONTROL INSTRUCTIONS
11.3 Control Operation Instructions
• A change in the input data and variation rate alarm value (DPL) are compared every execution cycle (
T).
*1 If ERRI or DPPI of disable alarm detection (INH) is set to 1, the DPPA of ALM and BB4 are set to 0.
*2 If ERRI or DPNI of disable alarm detection (INH) is set to 1, the DPNA of ALM and BB5 are set to 0.
■
Engineering value transformation (4)
The instruction performs engineering value transformation using the following expression.
■
Loop stop processing (5)
The following processing is performed according to the SPA status of the alarm detection (ALM).

The loop stops. When the loop stops, the following operations are performed and the S.PHPL instruction ends.
• The instruction performs engineering value inverse transformation using the following expression.
• The alarm bits (BB1, BB2, BB3, BB4, and BB5) are set to 0.
• The DMLA, MHA, and DLA of alarm detection (ALM) are set to 0.
0
The loop runs and "engineering value inverse transformation (1)" is performed.
