Details
The current fixed cycle processing time is stored in SD520 and SD521.
(Measured in 1 s.)
• SD520: Stores an ms digit. (Storage range: 0 to 65535)
• SD521: Stores a s digit. (Storage range: 0 to 999)
When the current fixed cycle processing time is 23.6 ms; for example, it is
stored as follows:
• SD520 = 23 (ms)
• SD521 = 600 (s)
The minimum fixed cycle processing time is stored in SD522 and SD523.
(Measured in 1 s.)
• SD522: Stores an ms digit. (Storage range: 0 to 65535)
• SD523: Stores a s digit. (Storage range: 0 to 999)
When the minimum fixed cycle processing time is 23.6 ms; for example, it
is stored as follows:
• SD522 = 23 (ms)
• SD523 = 600 (s)
The maximum fixed cycle processing time is stored in SD524 and SD525.
(Measured in 1 s.)
• SD524: Stores an ms digit. (Storage range: 0 to 65535)
• SD525: Stores a s digit. (Storage range: 0 to 999)
When the maximum fixed cycle processing time is 23.6 ms; for example,
it is stored as follows:
• SD524 = 23 (ms)
• SD525 = 600 (s)
The current link refresh processing time is stored in SD526 and SD527.
(Measured in 1 s.)
• SD526: Stores an ms digit. (Storage range: 0 to 65535)
• SD527: Stores a s digit. (Storage range: 0 to 999)
When the current link refresh processing time is 23.6 ms; for example, it
is stored as follows:
• SD526 = 23 (ms)
• SD527 = 600 (s)
The minimum link refresh processing time is stored in SD528 and SD529.
(Measured in 1 s.)
• SD528: Stores an ms digit. (Storage range: 0 to 65535)
• SD529: Stores a s digit. (Storage range: 0 to 999)
When the minimum link refresh processing time is 23.6 ms; for example, it
is stored as follows:
• SD528 = 23 (ms)
• SD529 = 600 (s)
The maximum link refresh processing time is stored in SD530 and
SD531. (Measured in 1 s.)
• SD530: Stores an ms digit. (Storage range: 0 to 65535)
• SD531: Stores a s digit. (Storage range: 0 to 999)
When the maximum link refresh processing time is 23.6 ms; for example,
it is stored as follows:
• SD530 = 23 (ms)
• SD531 = 600 (s)
