Chapter1. FBs-W2C Wi-Fi Communication Module
Product Introduction
1.1 Summary
FBs-W2C is a Wi-Fi board plugged in the PLC, which enables wireless network
transmission capability. In addition, as a wireless communication module, it
supports Wi-Fi Station mode (STA mode) and needs to connect to router. In
order to make the W2C settings easier and more convenient, the Smart Config
function is provided to allow users to easily connect to the router via the mobile
app. This module breaks the traditional PLC only through wired transmission,
and the use is no longer subject to the physical network route. It can make
multiple PLCs establish connections through one AP at the same time. It is
superior to the traditional wired way in turns of maintenance.

detect the baud rate. After the detection, it will set the port 0 (port 1 for HB1
series) baud rate as 115200 bps.
If using HB1 series PLC, please update the firmware version of W2C to V1.3.1 or
above. The baud rate of the port 1 cannot use 4800 bps. For instructions on
firmware upgrade, please refer to Chapter5 Firmware Upgrade (OTA).

Chapter2. Wi-Fi Connection Setting
By installing the FBs-W2C Wi-Fi communication module, the PLC can connect to
the router for wireless network connection and transmission. Currently, the
wireless network connection can be set in the following two ways:
Setting through the PLC application interface.
Setting through mobile App under Smart Config (SC) mode.
2.1 PLC Application Interface Wi-Fi Setting
According to the PLC register configuration in Table 4, please create two ASCII
tables for SSID and Password and enter the Wi-Fi account and password you
want to connect into their respective tables. As shown in Figure 3~Figure 5,
please note that SSID and Password must be enclosed in single quotes.
After the connection is successful, the LINK LED will flash at 3s intervals (3
seconds on, 3 seconds off). If you want to reconnect or connect other router,
just write any value to R904, and the W2C will reconnect according to the
information of the current register.

2.2 Smart Config Wi-Fi Setting (SC)
For the convenience of use, the Smart Config connection method is also
provided. First you need to download the mobile app - Esptouch (support in iOS
/ Android), as shown below. Esptouch sends the SSID and Password of the
router via UDP broadcast. W2C connects according to the information received.

Figure 7: Android –Esptouch APP

FBs-W2C User Manual

To put the W2C into the Smart Config mode, needs to switch the W2C rapidly
3times in succession.
After the W2C is powered on, it must be powered off within three seconds.
After repeating twice, the Smart Config mode will be enabled when the third
power is turned on.
After entering the SC mode, W2C starts waiting for Esptouch broadcast
information. At this time, the LED will flash continuously to indicate that the APP
can start transmitting, the longest waiting time is 60 seconds.
If the connection fails after 60 seconds (such as wrong information, unstable
network quality), W2C will enter the PLC application interface mode and
connect through information stored in PLC before.
Since the Smart Config connection method is subject to the hardware
compatibility, we provide Appendix C-Access Point Compatibility Table for users
to choose the appropriate mobile phone for connection settings.

2.4 Wi-Fi RSSI
Wi-Fi RSSI is an indicator for measuring the strength of the signal received by the device in wireless
communication. In order to monitor the connection quality of the W2C, the user can view it through
the register R949 of the PLC. As shown in
Table 6, the signal strength is shown. Expressed as a negative number, the unit
is dBm, the value range is 0 ~ -100, the closer to 0, the better the signal strength.

Chapter3. FATEK Standard Communication Service
PLC has wireless network communication capability by plugging FBs-W2C Wi-Fi
communication module. It can communicate with objects such as WinProladder
that use FATEK standard communication in the same local area network.
Supporting IPv4 and TCP/UDP protocols, can up to 4 TCP connections at the
same time. Default port of TCP/UDP are 500, it can be modified by PLC register,
shown as Table 7.

In order to ensure the successful exchange of communication data in a wireless
environment, it is recommended to set the Time out and Retry as follow:
Time out : 3 sec
Retry : 5 times

Chapter4. Simple Network Time Protocol (SNTP)
In addition to the above functions, the PLC with the FBs-W2C Wi-Fi
communication module can be used to perform network time correction via the
NTP Server and support two synchronization modes according to different PLC
register value.
Sync mode 1: Synchronize time back to PLC RTC.
(For more details can refer PLC user manual 2 advanced application
chapter15: RTC)
Sync mode 2: Synchronize time back to specified PLC register.
The user can flexibly select different mode according to individual needs. The
PLC register configuration of these two modes is shown in Table 8.
In addition, W2C will automatically perform time correction with NTP Server at
the following timing, and update the time to the PLC registers.
①When W2C is powered on, the time of W2C and time in corresponding PLC
registers according to the mode will be synchronized with NTP server.
②Every 24 hours after powered on, the time of W2C and time in
corresponding PLC registers according to the mode will be synchronized
with NTP server.
The W2C also provides the user to manually update the time to the PLC register.
Simply set the value of the register R908 to 1, and the time will be updated to
the corresponding register according to the selected mode.
In addition, if you want to change the time zone, you can refer to Appendix
B-Time Zone Table. The time zone is the daylight time (if there is one in the
area), input the index value of the desired area into the register R910, and then
input 1 to the register to R908, the time will be updated.
If the entered index value is exceeded or not in the Appendix B table, the system
default area is Taipei.
If the SNTP server needs to be changed to another server, the new URL can be
written to the register and enable the corresponding PLC register to notify W2C
there’s a new setting needs to changed, default setting of SNTP server is ”
pool.ntp.org”, W2C will synchronize time with SNTP server every 24 hours after
powered on, the functions of SNTP and the configuration of the PLC register are
shown in
Table 9.

Chapter5. Firmware Upgrade (OTA)
OTA is a function to update the W2C firmware through the cloud. W2C will
check the version information in the "w2c_info" file on the cloud to determine
whether it needs to be updated. If a new version is found, the PLC
corresponding register will be set to 1, means users can update new firmware
for the W2C.
W2C will check the latest version on the cloud when it connects to AP and every
morning 00:01.
When the user wants to update the firmware, W2C will check whether the
cloud has a new version. If there is, the W2C will immediately update the
firmware of the OTA. If it is not found, it will go to the cloud to check the version
information again. The result will be checked. Decide whether to allow updates.
When updating the firmware, LINK LED will flash three times per second then
off one second, PLC register configuration description as Table 10.
