17. RESPONSE DELAY TIME
The maximum response delay time of the complete system, calculated by considering the
scan period of the DeviceNet scanner,
SL-GU1-D
processing time,
S-LINK
system transmis-
sion time, etc., is as given below.
1. Input response delay time of complete system
= Response time of external Input response delay time of
S-LINK
DeviceNet
scan time
2. Output response delay time of complete system
= DeviceNet scan time + Output response delay time of
S-LINK
Response time of
external device
where,
Input response delay time of
S-LINK system
=
S-LINK
input unit processing time +
S-LINK
system transmission time +
SL-GU1-D
pro-
cessing time
Output response delay time of
S-LINK system
=
SL-GU1-D
processing time +
S-LINK
output unit processing time +
S-LINK

mission time

18. SWITCHING ON AND OFF OF POWER SUPPLY
In case a local power supply is used for the connected devices and the
S-LINK
units, switch
;*
In case the booster (
SL-BS1A
), is used with a local power supply, switch on the supply of
SL-BS1A
, either earlier or at the same time as the supply of
SL-GU1-D
.
