1. Introduction
The WF-2000 RevB series I/O modules have WLAN connection
complies with the IEEE802.11b/g/n standards. With the popularity of
802.11 network infrastructure, the WF-2000 RevB series I/O modules
make an easy way to incorporate wireless connectivity into monitoring
and control systems. They also support Modbus/TCP and UDP protocol
and the network encryption configuration, which makes perfect integration
to SCADA software and offer easy and safe access for users from anytime
and anywhere.

1.2.1 Features Description
The WF-2000 module 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
WF-2000 RevB module complied with IEEE 802.11b/g/n standard
from 2.4~2.5 GHz, and it can be used to provide up to 11 Mbps for IEEE
802.11b, 54 Mbps for IEEE 802.11g and 72 Mbps for IEEE 802.11n to
connect your wireless LAN.
Support infrastructure and Limited-AP modes for wireless networks
Limited-AP mode lets you create a Limited AP network with the
specified SSID to communicate directly with each other without the need
for a wireless access point.
Infrastructure 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, WF-2000 module
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 and UDP protocols
The Modbus/TCP and UDP slave function on the WF-2000 module
can be used to provide data to remote HMI/SCADA software built with
Modbus/TCP driver. ICP DAS also provides NAPOPC_ST DA Server for
Modbus/TCP to integrate WF-2000 I/O series real-time data value with
OPC client enabled software.

Built-in Multi-function I/O
Various I/O components are mixed with multiple channels in a single
module, which provides the most cost effective I/O usage and enhances
performance of the I/O operations.
Built-in Watchdog
Module Watchdog is a built-in hardware circuit that monitors the
operating status of the module and will reset the module if a failure occurs
in the hardware or the software.
