Introduction

Pick-to-Light is used primarily in warehouse and distribution center operations to optimize order picking and kit assembly processes. Our Pick-to-Light solution consists of a Pick-to-Light Gateway and a number of Pick-to-Light Nodes.

This guide provides information on the operation and features of our Pick-to-Light system.

Main Features

Pick-to-Light Gateway

The Pick-to-Light Gateway is the control device of the system. The gateway has Modbus RTU and Web interfaces. The gateway communicates with Nodes via Modbus RTU interface. The Web interface of the Gateway is used to control the system. You can log in to the web interface as user or administrator. When logged in as an administrator, Gateway and Nodes can be configured, and recipes can be created and run. When logged in as a user, the recipes can only be viewed and executed.

Pick-to-Light Node

The Pick-to-Light Node has a Modbus RTU interface. This interface is reached by 4 pin GX12 male connectors located on both sides of the device. 2 pins of GX12 connectors are used for Modbus RTU, 2 pins are used for ground and 12~24VDC power.

The nodes have a 3-character 7-segment LED display, RGB light signal button and optical sensor to interact with the user. The Gateway can detect whether the user triggers the button or optical sensor.

Each node has one "Device ID" and one "Common ID". The "Device ID" must be unique for each device in a system. The "Common ID" must be common across all devices in the system. The default device ID and common ID for a device are "1" and "195", respectively. Both IDs can be changed via Gateway upon request.

The Show ID button is used to show the device ID of the nodes on the 7-segment led display. After pressing the Show ID button, the name of the button changes to "Don’t Show ID". To end the display of IDs, the "Do Not Show ID" button must be pressed.

Set One ID is used to change the device IDs of nodes. When Set One ID button is pressed, the "Set One ID" dialog box is displayed on the screen.

With the "Set" button of "Set One ID" dialog box, a new ID is assigned to a device whose device ID is known. With the "Set to All" button of this dialog box, the device ID is assigned to an unknown device or all devices connected to the system.

The set ID sequentially button is used to change the device IDs of nodes by triggering devices sequentially. When Set ID Sequentially button is pressed, the "Set ID Sequentially" dialog box is displayed on the screen.

To set ID sequentially, the Common ID of the devices must be known. The Common ID is used to identify triggered devices. After typing the common ID in this dialog box, the first ID to be assigned to the devices and the last ID should be written. The last ID can be greater than or equal to the last device ID to be assigned.

After the common, first and last IDs are entered, the "Start" button is pressed to perform the assignment process and individual devices are triggered. Triggered devices will first have an error light and then the ID assigned to the device will be shown.

When the sequential ID assignment process is complete, the sequential ID assignment process is terminated by pressing the "End" button.

The check device button is used to check the connections of devices in the system. When the check device button is pressed, the "Check Device" dialog box is shown on the screen.

In the check device dialog box, the IDs of the first device to be checked and the last device to be checked are entered. Then the "Start" button is pressed. The gateway sequentially sends show ID command to individual devices within the entered range, making devices to show their IDs.

The "Finish" button is pressed to end the device inspection process.

The light setup button is used to change the status lights and texts of nodes. When the light setup button is pressed, the "Light Setup" dialog box is shown on the display.
