CHAPTER 6 RAS FEATURES IN HF-W100E/IoT
6.1 Overview
In addition to the standard RAS features on HF-W, HF-W100E/IoT offers additional HF-
W100E/IoT's own RAS features. These include such functionalities as the ability to control
hardware from the CODESYS runtime environment and to monitor the CODESYS runtime
environment.
This section provides an overview of the HF-W100E/IoT's own RAS features.

<Control functionality>
(1) Controlling the external general purpose I/O
You can use the RAS library for the CODESYS runtime environment to control external
general purpose I/O from applications running on the CODESYS runtime environment.
If you use this functionality, you can input signals from and output signals to external
devices. Seven input and eight output external general purpose I/O are available for a
user.
<Monitoring functionality>
(2) Monitoring the CODESYS runtime environment
You can use a watchdog timer on HF-W100E/IoT to monitor whether the CODESYS
runtime environment is running properly. If any abnormality is detected, it is recorded in
the Windows event log and notified to user applications by using an event object.
This chapter describes functionalities (1), (2) offered by the HF-W100E/IoT's own RAS
features.
