1. Introduction
The WF-2000 series I/O modules have WLAN connection complies
with the IEEE802.11b/g standards. With the popularity of 802.11 network
infrastructure, the WF-2000 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 standards
WF-2000 module complied with IEEE 802.11b/g standard from
2.4~2.5GHz, and it can be used to provide up to 11Mbps for IEEE
802.11b and 54Mbps for 2.4GHz IEEE 802.11g to connect your wireless
LAN.
Support infrastructure and ad hoc modes for wireless networks
Ad hoc mode lets you create a wireless network quickly by allowing
wireless nodes within range (for example, the wireless devices in a room)
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.
Safe value mechanism
Safe value mechanism is a software function that monitors the
operating status of the host, and is used to prevent network
communication problems or host failures. When a host watchdog timeout
occurs, the module will reset all outputs to safe states in order to prevent
any erroneous operations of the controlled target.
I/O Pair Connection
This function is used to create a DI to DO (AI to AO) pair through the
Ethernet. Once the configuration is completed, the WF-2000 module can
poll the status of remote input devices using the Modbus TCP protocol
and then continuously write to local outputs in the background.

2.5 Watchdog Timer Settings
A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes wrong and the
system does not recover on its own. A watchdog timer can perform a
warm boot(restarting the system) after a certain number of milliseconds.
The WF-2000 series module supplies a jumper for users to active the
watchdog timer or not. If users want to use this WDT, can open the WF-
2000 cover and use the JP1 to activate the WDT built in the module, as
the Figure 2-6. Note that the default setting is active.
Enable (default) Disable
Figure 2-6: Watchdog timer JP1 Jumper Position
2.6 FW / OP Dip-switch
On the top of the WF-2000 series module, there is a dip-switch used
for firmware operation or firmware update of the module. The following
steps show how to use this dip-switch.
2.6.1 Firmware Update Mode
Please set the dip-switch to the “FW” position as Figure 2-7, and then
the WF-2000 series will work in the “Firmware Update Mode” after reset
the power of the module. In this mode, users can update the firmware of
the WF-2000 module from computer’s RS-232 port via CA-0910 cable
shown as Figure 2-8.
