POINT
When the Secured data send/receive setting is enabled, the transmission
delay time (T
DB2
) is calculated as follows:
• [Remote master station scan time (Sm) > Link scan time (LS)]
T
DB2
= (Sm + αm) + LS + T
RBF
[ms]
• [Remote master station scan time (Sm) < Link scan time (LS)]
T
DB2
= (Sm + αm) x round up[LS/(Sm + αm)] x 2 + LS + T
