Introduction

Introduction
This manual is divided in three parts:
1. Ladder Logic: We describe control elements of a control strategy available in the LOGICVIEW and
used by the DF65.
2. Function Blocks: We present detailed descriptions of all function blocks available in the LOGICVIEW
and used by the DF65.
3. LOGICVIEW: We describe Smar’s Software LOGICVIEW. This is the application used to configure the
hardware of a control system (I/O Modules, Power Supplies, CPU, etc), implement ladder logic
(including ladder network elements and function blocks)
We suggest user to read initially chapters 1 and 2 and next going to chapter 3 that describes clearly how
to implement elements described in the first two chapters. However, user is free to start reading from
chapter 3 prior to the other ones and consult chapters 1 and 2 any time it is necessary. Chapter 3 deals
with description of the Smar’s LOGICVIEW Software that is part of the DF65 System.
This manual has practical examples that describe step-to-step how to set strategies of control. These
examples were included in order to make easier user’s understanding of the system. These applications
are distributed along this manual.

DF65 – LogicView Configuration Manual

NOTE
This document is a description of all function blocks and logic elements (ladder) implemented in the coprocessor
(DF65). Besides this document presents a description of how to configure and edit ladder networks through Smar’s
LOGICVIEW. This document also describes details of this software.
Smar reserves it the right to change any part of this manual without prior notice.
Note that different versions of the DF65 have different types of data, function blocks and generic characteristics. The
last version of the DF65 is always an update of the old manual without prior notice. It means it will have all
characteristics included, old and new ones.
