Preface

Logicmaster 90-70 Programming Software User's Manual (GFK-0263). A programming software user's manual for system operators and others using the Logicmaster 90-70 software to program, configure, monitor, or control a Series 90-70 PLC system.

Series 90-70 PLC CPU Instruction Set Reference Manual (GFK-0265). Reference manual which describes operation, fault handling, and programming instructions for the Series 90-70 PLC.

Series 90-70 System Manual for Control Software Users (GFK-1192). Provides an overview of hardware and software features of the Series 90-70 PLC.

Series 90-70 Remote I/O Scanner User's Manual (GFK-0579). Reference manual for the Remote I/O Scanner, which interfaces a drop containing Series 90-70 modules to a Genius bus. Any CPU capable of controlling the bus can be used as the host. This book describes the Remote I/O Scanner features, configuration, and operation.

Series 90-70 Bus Controller User's Manual (GFK-0398). Reference manual for the bus controller, which interfaces a Genius bus to a Series 90-70 PLC. This manual describes the installation and operation of the Bus Controller. It also contains the programming information needed to interface Genius I/O devices to a Series 90-70 PLC.

Control User’s Guide (GFK-1295). Describes configuration and programming software using Control Programming. Control software, release 2.1 or later is required to configure Ethernet Global Data as described in this manual.
