Page 4: Introduction
1 INTRODUCTION 1.1 OVERVIEW The REDS function replicates the SC6000 controller, the presence sensor and the encoder devices. The scanner network is not replicated as it already implements a form of redundancy. 1.2 BASIC CONCEPTS REDS is based on the following: •... -
Page 5: Presence Sensor And Encoder
1.3.3 Presence Sensor and Encoder Each controller has its own presence sensor and encoder. The scanners use the active controller’s encoder signal. No presence sensor signal is used by the scanners (only PackTrack mode is supported). 1.3.4 Redundancy Cable A dedicated cable (Lonworks + Serial) is used both to interconnect the two halves of the Lonworks network and exchange redundancy data. -

Page 8: Notes
Configure the Redundancy Parameters on the SC6000 as described in paragraph 2.7.1 Master Working Controller REDS configuration of this document. Configure the SC6000 for Code Selection, Data Formatting and all the necessary parameters. Send the configuration to the Working Controller with Options + Environmental Parameters as follow: Genius... -
Page 9: Presence Sensors And Encoders
This is the easiest and preferred way because the PS Line parameters and the Pack/Track origin XYZ=0 are equal for both SC6000. In this case it is not possible to detect lower packs with both photocells because they are at different height, one over the other. -
Page 10: Ps Line
2.5.4 PS Line 2.5.5 Encoders mounting Both encoders must give to the controllers the same information at the same time, so some precautions must be taken: The Encoders must be mounted on the same belt. The Encoders switch setting and wheels dimension must be the same. Make sure that both Encoders wheels have the right touching pressure on the belt in order to avoid detaching that produce different speed. -
Page 11: Redundancy Scanner Connections
2.6 REDUNDANCY SCANNER CONNECTIONS Reliability and robustness of the system can be improved by connecting scanners together in a particular way. In case of failure for the redundancy cable, which connects the two PWOs together, the active device only sees the scanners physically attached to the relative PWO. In this case, the best result will be achieved if the scanners in question read as much as possible over the entire reading area. -

3 REDS REDUNDANCY SYSTEMS 3.1 DIAGNOSTIC PROCEDURES The messages exchanged by the controllers over the redundancy cable are of two different types: 1. Notification of the redundancy role 2. Diagnostic status (presence sensor and encoder status) Notifications are used both at initialization time and runtime (cyclic notifications). Diagnostic status exchange (cyclic) conveys diagnostic data and is used only by the Standby controller to validate the status of the active controller. -
Page 16: Configuration
If compared with a stand-alone station, no additional settings are needed on the slave scanners when the REDS function is used. All the parameters related to REDS function have to be set on the active SC6000 as described in the following. A simple procedure (see par. 3.2.3 Alignment of the Configuration on the Protecting Controller) is needed to align the reserve SC6000. -
Page 17: Standby-Active Switch Over
3.3 STANDBY-ACTIVE SWITCH OVER The switch over is the situation that leads to a swapping of the role that the controllers play in the redundant system. The Standby controller is responsible for the decision to switch over as a final result of the evaluation of the local and remote diagnostics or of parcel error count conditions. -
Page 18: Validation Of The Parcel Error Count Condition
On the Standby controller, the comparison of the local/remote data is based on a table that summarizes the configuration of the validating rules that contains the following parameters both for the encoders and for the presence sensors: • Validation procedure enabling/disabling flag. •... -
Page 19: Host Interface
Various alarms can be sent by REDS to the host computer through the standard communication ports, based on the standard SC6000 diagnostics. 3.6 POWER SUPPLY Two separate paralleled power supplies are present to supply power both to the controllers and the scanners. -
Page 20: Dual Ethernet
3.7 DUAL ETHERNET Each controller (Dual Ethernet models) is able to interface to the host computer through two different Ethernet networks. The dual Ethernet is intended to allow the physical replication of the connection to the host computer, however dual Ethernet is not managed by REDS. 3.8 GENIUS CONFIGURATION PARAMETERS Parameter Values (default) - Page 21 Mode 0 / Mode 1 Leve set as Default (Mode 0) Mode Data Communication Setting \Built-in Ethernet\LineParameters IP-address Active * IP address Active SC6000 IP-address Standby * IP address Standby SC6000 Only Dual Ethernet Models Data Communication Setting \Additional Ethernet\LineParameters...
