AND PROCESSING TlME
Examples:
(1)
(2)
(3)
When the master station for the third tier executes link refresh after the execution of an
END instruction of a sequence program, add the L1/m scan time to the values obtained
with calculation in (1)(b) or (2)(b). If (3)(b) is used for the calculation, add the L2/m scan
time.
To transmit B/W data from M to 1
(a) If (L1/m scan time) > (third tier-1 link scan time)
(Transmission delay time from M to L1/m) + (Transmission delay time from L1/m
to 1) + (L1/m scan time)
(b) If (L1/m scan time) < (third tier-1 link scan time)
(Transmission delay time from M to L1/m) + (Transmission delay time from L1/m
to 1) + (third tier-1 link scan time)
To transmit B/W data from 1 to M
(a) If (L1/m scan time) > (third tier-1 link scan time)
(Transmission delay time from 1 to L1/m) + (Transmission delay time from L1/
m to M) + (L1/m scan time)
(b) If (L1/m scan time) < (third tier-1 link scan time)
(Transmission delay time from 1 to L1/m) + (Transmission delay time from L1/
m to M) + (third tier-1 link scan time)
To transmit B/W data from '1 to L3
(a) If (L2/m scan time) > (third tier-2 link scan time)
(Transmission delay time from '1 to L2/m) + (Transmission delay time from L2/
m to L3) + (L2/m scan time)
(b) If (L2/m scan time) < (third tier-2 link scan time)
(Transmission delay time from '1 to L2/m) + (Transmission delay time from L2/
m to L3) + (third tier-2 link scan time)
