Emerson ROC827 instruction manual Expanded Backplane

ROC827 Instruction Manual

DS800 Development Suite software allows programming in all five of the

IEC 61131-3 languages:

ƒLadder Logic Diagrams (LD).

ƒSequential Function Chart (SFC).

ƒFunction Block Diagram (FBD).

ƒStructured Text (ST).

ƒInstruction List (IL).

A Flow Chart language provides a sixth programming language. With these six languages, FSTs, and built-in functionality, you can configure and program the ROC827 in an environment in which you are comfortable.

You can download and implement programs developed in the DS800 Development Suite software in the ROC827 in addition to—or as an alternative to—FST programs. DS800 software has definite benefits for programmers who prefer to use the IEC 61131-3 languages, who desire to multi-drop units in a distributed architecture, or who desire enhanced program diagnostics capabilities.

Additional DS800 Development Suite software features include:

ƒCross-reference (bindings) between variables in separate ROC827 units.

ƒVariable Dictionary.

ƒOff-line simulation for diagnostics and testing.

ƒOn-line modification of programs.

ƒOn-line debugging of programs.

ƒLocking and forcing of variables.

ƒUser developed functions and function blocks.

ƒUser defined templates.

ƒCreation and support of user defined libraries.

1.7Expanded Backplane

The expanded backplane is a key component to the ability of the ROC827 to expand its I/O capabilities to meet your needs. The ROC827 base unit can accommodate up to four additional expanded backplanes, which easily snap together. This increases the total number of available I/O slots to 27. Refer to Chapter 2, Installation and Use, for instructions on adding backplanes to the ROC827 base unit. Refer to Chapter 3, Power Connections, to assess the power requirements for any particular I/O configuration.
