Appendix 4.4 Transmission Delay Time Of Master Station <-> Remote Device Station; (Ver.2 Compatible Device Station) - Mitsubishi Electric L26CPU-BT User Manual

Appendix 4.4
(1) Master station (RX)  Remote device station (RX), (RWr)
This indicates the time from when a signal is input to a remote device station until the corresponding CPU device
turns ON (OFF) or CPU device data is changed.
(a) Expression
The meanings of symbols in the table are as follows:
• SM: Master station sequence scan time
• LS: Link scan time
• n: LS  SM (Digits past the decimal point are rounded up to the nearest integer.)
• t: LS  m  SM (Digits past the decimal point are rounded up to the nearest integer.)
• Rd: Remote device station processing time
• m: Constant set in the extended cyclic setting
Expanded cyclic setting
With block guarantee of cyclic data per station
Calculation
value
Asynchronous mode
(SM  n) + (LS  1  m) + Rd
Normal value
(SM  n) + (LS  2  m) + Rd
Max. value
(b) Calculation example
Master station sequence scan time of 20ms, link scan time of 3ms, and the expanded cyclic setting "double".
With block guarantee of cyclic data per station
Calculation
value
Asynchronous mode
(20  1) + (3  1  3) + 1.5 = 30.5ms
Normal value
(20  1) + (3  2  3) + 1.5 = 39.5ms
Max. value
