Using Unit for Optical Bus Repeater Module
This section explains how to connect the optical bus repeater module with a mounted optical
ESB bus repeater to a safety control unit and a safety node unit. Both ends of the ESB bus
should be terminated on each level. The following figure shows an example of this connec-
tion.
Mount the ESB bus coupler module (SEC401) on the safety control unit (SSC10S/SSC10D);
mount the optical ESB bus repeater master module (SNT401) on the unit for optical bus re-
peater module (SNT10D);connect the SEC401 and the SNT401 with the ESB bus.
Mount the ESB bus interface module (SSB401) on the safety node unit (SNB10D); mount the
optical ESB bus repeater master module (SNT401) and the optical ESB bus repeater slave
module (SNT501) on the unit for optical bus repeater module (SNT10D);connect the SSB401
and the SNT401 with the ESB bus.
Mount the ESB bus interface module (SSB401) on the lowest-level safety node unit
(SNB10D); mount the optical ESB bus repeater slave module (SNT501) on the unit for optical
bus repeater module (SNT10D);connect the SSB401 and the SNT501 with the ESB bus.
For the modules at the ends of ESB bus, use a connector unit with terminator for ESB bus.
Connect the optical ESB bus repeater modules with fiber-optic cables.
