1.2.2 Features Description
The tWF-DA1PD2R1 offers the most comprehensive configuration to meet specific
application requirements. The following list shows the features designed to simplify
installation, configuration and application.
Compatible with IEEE 802.11b/g/n standards
tWF controller complied with IEEE 802.11b/g/n standard from 2.4~2.5 GHz, and it
can be used to connect your wireless LAN.
Support STA(Station) and AP(Access Point) modes for wireless networks
AP mode lets you create a Limited AP(1 Client access allow) network with the
specified SSID to communicate directly with each other without the need for a wireless
access point.
STA mode is the more common network configuration where all wireless hosts
(clients) connect to the wireless network via a WAP (Wireless Access Point).
Support WEP, WPA and WPA2 wireless encryption
WEP and WPA are common types of security that are used to protect wireless
networks. When WEP or WPA is turned on, tWF controller uses a special security key
combination to allow only devices that know this key to connect to its wireless network.
This applies to laptops, smart device, or any other wireless device.
Support Modbus TCP protocols
The Modbus TCP server function on tWF-DA1PD2R1 can be used to provide data
remote with HMI/SCADA software built with Modbus TCP driver.
Also there is some other HMI Modbus App in Android Google Play you can use.
Built-in Software counter for Digital Input
Each of the Digital Input port have a 32-bit (4294967295) software counter, use to
count the input triggered, it can be reset from utility or Web browser.
Built-in Multi-function I/O
Various I/O components are mixed with multiple channels in a single controller,
which provides the most cost effective DA output, I/O usage and enhances performance of
the I/O operations.

Built-in Simplify Light control function
Light control can be config by Utility, WEB, APP, using DI pin to trigger DO output
and DA output with timing operations.
