WCL-920R

1-4．Outline
WCL-920R is a LAN connection type Andon*1 receiver (hereinafter called “receiver”).
The receiver can wirelessly receive in real-time trouble occurrence reports transmitted from the AN920T
transmitter installed at the workstations and machines of the production line.
In addition, the receiver can externally output the received reports of trouble occurrence via LAN.
By utilizing and analyzing the information of trouble occurrences on the production line with applications on
computers, tablets and in the cloud, the receiver can be useful for visualizing and improving the operation
status of the production line.
Using the Windows application “Production Process Support Software for WCL Series WCL plus,” you cansave the trouble occurrence history received by up to 10 Andon receivers in the CSV format.
●At the transmitter, there are two selectable input methods for reporting trouble occurrences: one forworkers with four push-buttons (orange, red, green, and white) and one for machines with four external
inputs (orange, red, green, and white). According to possible trouble occurrences in the production line, you
can assign each color a meaning, such as red for an exception occurrence, orange for parts out of stock,green for requesting transportation of finished products, or white for trouble solved.
●When using the receiver linked to a wireless Andon series AN920, one receiver can wirelessly
communicate with up to 800 transmitters and a maximum of 16 receivers can be used in a factory. This
enables trouble occurrence reports to be collected from up to 12,800 locations in a factory.
When using the receiver with the transmitter without linking to a wireless Andon series AN920, each receiver
can wirelessly communicate with up to 1,000 transmitters and a maximum of 16 receivers can be usedwithin a factory. This enables trouble occurrence reports to be collected from up to 16,000 locations in afactory.
*1: A system to notify management, maintenance, and other workers of a quality or process problem.

9-1-2．Receive Data from Transmitter
Upon receipt of a message from the transmitter, the receiver generates the output of the information in
TCP/IP.
Message data with the same channel as the receiver is generated. After receiving a message, when
receiving the same message within 2 seconds, the message will be thrown away after reading and will not
be generated. The output data formats are as follows.
The items between Model and Output power settings are separated with commas [,].

9-3．Processing at Power ON
At power ON, the receiver reads the settings required to work. If the receiver fails to read them, the LED
indication and settings may be forcibly initialized.
■Read serial number
At power on, the receiver reads the serial number stored in the code flash region.
If an error occurs while reading the serial number, the LEDs for wireless communication and wired
communication blink in orange (blinking interval of 100msec). Also, error information output is generated in
TCP/IP. If an error occurs while reading the serial number, the LED for wireless communication and wired
communication continue blinking until the power is OFF. The error information output to be generated is asfollows:@!ErrorData Error=4.2■Read the channel settings, the answerback invalid settings, and the terminal code settings for the Ethernet
communication command.
When the Ethernet communication command is valid, the receiver reads the channel settings, theanswerback invalid settings and the terminal code settings for the Ethernet communication command stored
in the data flash region, at power on.
When the Ethernet communication command is invalid, the receiver reads the channel settings and theanswerback invalid settings from various switches.
When an error occurs while reading them, the LEDs for wireless communication and wired communication
blink in orange for 5 seconds (blinking interval of 100msec). Also, error information output is generated in
TCP/IP. The error information output to be generated is as follows:@!ErrorData Error=4.3
In the following cases, the set values are forcibly set to default.
• Failed to read the channel settings, the answerback invalid settings and the terminal code settings for
the Ethernet communication command.
• Set the Ethernet communication command to valid for the first time.
The default values are as follows:

CRLF■Initialization of wireless module
At power ON, the receiver initializes the wireless module.
If the receiver fails to initialize it, the LED for wireless communication blinks in orange for 5 seconds (blinking
interval of 100msec). Also, error information output is generated in TCP/IP.
Initialization processing continues until it succeeds. The error information to be output is as follows:@!ErrorData Error=5.1
When the above symptom occurs and the error continues, there may be some damage to the module. Inthat case, please contact the sales distributor you purchased the product from, or contact our sales
department.
