(9) Scan time measurement
When the scan time is measured (Page 181, Section 3.13.3), the processing time listed in the following table is
required.
*1 The number of the branch instructions is a total of the following instructions, which are executed during the scan time
measurement.
• Pointer branch instruction: CJ, SCJ, JMP
• Subroutine program call instruction: CALL(P), FCALL(P), ECALL(P), EFCALL(P), XCALL(P), RET
(10)Monitor condition setting
When the monitor condition is set (Page 146, Section 3.11.1), the processing time listed in the following table is
required.
(11)Time taken to collect module errors
When using the module error collection, the scan time increases by the time found by the following calculation
formula. Each N1 and N2 in the calculation formula indicates the following.
 Calculation formula
Collection time = N1 + N2 × (Number of module errors collected in one scan)
