CHAPTER 1 INTRODUCTION TO HF-W100E/IoT
1.1 Overview
The HF-W100E/IoT is a Hitachi industrial computer HF-W100E equipped with a software
PLC. It has the features of both an industrial computer and a programmable logic controller
(PLC).
A software PLC is a development environment/runtime environment that executes PLC
functions on a computer with a general-purpose OS. HF-W100E/IoT uses CODESYS®, a
software PLC developed by 3S-Smart Software Solutions GmbH, Germany (hereinafter
denoted as 3S).
About CODESYS
CODESYS is a software PLC developed by 3S. It consists of a development environment
that supports programming languages defined in the international standard IEC 61131-3
and a realtime execution environment (runtime environment) that runs control applications
developed by the development environment.
In HF-W100E/IoT, the following CODESYS packages are pre-installed. (You can
download the development environment from the Web site of 3S, but note that only the
following version is verified to work with the HF-W100E/IoT.)
• Development environment: CODESYS Development System (V3.5 SP10 Patch 1)
• Runtime environment: CODESYS Control Softmotion RTE (V3.5 SP10 Patch 1)
Using CODESYS
For information about the instructions on how to use CODESYS not described in this
manual, refer to the online help for the development environment. You can start the online
help on the help menu in CODESYS.
In addition to the online help, CODESYS original manuals (PDF format in English) from
3S are available and stored in the following locations. Refer to them when needed.
Note that Adobe® Reader® from Adobe Systems Incorporated is required to read a PDF
file.
