S-LINK
‘T’-branch Multi-drop
• Seamless connection to fieldbus networks
•S-LINK can be connected seamlessly to fieldbus networks
using the S-LINK gateway controllers.
• Advanced wire-saving connection with S-LINK and
fieldbus networks
•Wire-saving connections can be realized even when using
fieldbus networks. An efficient wire-saving network can be
implemented by connecting distributed bit level data I/O
devices, such as, sensors, switches, etc., by S-LINK.
• Personal computer can be used as master (for JPCN-1/RS-485)
•PC/AT or compatible (ISA bus), NEC PC/FC-98 series personal computer or PC/104 bus board can be used as a master
unit. Long distance and multi-point control is easily possible with a personal computer when the JPCN-1/RS-485 master
board and the S-LINK gateway controller for JPCN-1/RS-485, SL-CU1-485, are used.
•The master boards for personal computers can be used in the following two modes:
•1 S-LINK mode (using RS-485 communication)
•2 JPCN-1 mode
(Please arrange a driver software separately, when using the JPCN-1 mode.)

Advantage of using with higher level networks
• Long distance transmission
The max. transmission distance is as follows.
DeviceNet: 500m, PROFIBUS-DP and CC-Link: 1,200m,
INTERBUS: 13km, JPCN-1/RS-485: 1,000m.
S-LINK can transmit up to 400m using the booster
(SL-BS1A). Hence, a system of total 1,600m can be con-
structed with PROFIBUS-DP or CC-Link (DeviceNet:
900m, INTERBUS: 13.4km).
• Total I/O channels 8,064 Nos.
Up to 99 Nos. of S-LINK gateway controllers can be con-
nected as slaves to one PROFIBUS-DP master unit
[DeviceNet: 63 Nos., INTERBUS: 256 Nos., JPCN-1/
RS-485: 31 Nos., CC-Link: 32 Nos. (Note 2)]. Since max.
128 Nos. I/O devices can be connected to one S-LINK
gateway controller, I/O signal of total 12,672 channels
[DeviceNet: 8,064 channels, INTERBUS: 4,096 channels
(Note 3), JPCN-1/RS-485: 3,968 channels, CC-Link:
2,048 channels (Note 2)] can be transmitted.

Since the higher level networks mostly use cascade wiring with
shielded twisted pair cable, the flexibility in wiring and wiring
operations have not improved. In S-LINK, ‘T’-branch flexible lay-
out can be realized using different types of quick connecting
hook-up connectors, and distributed ON/OFF data devices, such
as, switches, sensors, etc., can be efficiently wired. In this man-
ner, an exceedingly efficient wire-saving link system can be real-
ized in combination with higher level networks.
Notes: 1) The total No. of I/O channels may be less than the maximum No.
mentioned above depending on the master unit capacity. Also, the
No. of devices connectable to the S-LINK system may be less than
128 Nos., depending on the type of devices and places connected.
Notes: 2)
In case of the S-LINK gateway controller for CC-Link, the No. of
controllable I/O channels varies with the No. of units connected to
CC-Link.
Notes: 3) For INTERBUS, one master unit can control up to 4,096 I/O chan-
nels only.
