Preface
This manual is a reference to planning, configuring and programming a Series 90 -70 PLC
system that utilizes Genius Modular Redundancy (GMR).
The information in this manual is intended to supplement the basic system installation,
programming, and configuration instructions located in the manuals listed on the next page.
Content of this Manual
Chapter 1. Introduction: describes the concept of GMR, and gives an overview of
system components, configuration, and programming.
Chapter 2. Input Subsystem: provides information about the inputs to a GMR system.
Chapter 3. Output Subsystem: describes GMR output groups, output handling, manual
output controls, and load sharing.
Chapter 4. PLC Operation: describes system startup, the CPU sweep in a GMR system,
PLC operation, I/O processing, and communications between redundant PLCs
Chapter 5. Diagnostics: chapter 5 describes the various types of diagnostics available in
a GMR system.
Chapter 6. Configuration: describes configuration for a Series 90-70/Genius GMR system.
Chapter 7. Programming Information: describes the application program interface to
the GMR software.
Chapter 8. Installation Information: provides supplementary installation information
for GMR.
Appendix A. TÜV Certification: describes restrictions placed on the design,
configuration, installation and use of a GMR system that will be applied in an
Emergency Shut Down (ESD) application, for which for a TÜV site application approval
will be sought.
Appendix B. Maintenance Override: The information in this appendix is reprinted by
permission of TÜV. Suggestions are made about the use of maintenance override of
safety relevant sensors and actuators. Ways are shown to overcome the safety problems
and the inconvenience of hardwired solutions. A checklist is given.
Changes for this Version of the Manual
This manual describes a group of features and product enhancements that are
collectively referred to as “GMR Phase II”:
Programming can now be done online. This capability is intended for use during
debug and commissioning.
32-circuit DC Genius I/O blocks can now be used in ”H-pattern” output subsystems.
