Device List - Link150 UG

Description

The device list is used for defining the list of devices connected to the Ethernet port or serial port.

The list of connected devices is defined manually by adding individual devices.

Master Mode Device List Setup

For Master mode, the usage of the COM port is:

Modbus RTU devices do not have to be defined in the Device List, but it helps you manage your system.
PowerLogic^TM protocol (SY/MAX) devices must be defined in the Device List.

NOTE: If none of the protocols are defined, Modbus RTU is available as a default protocol.

NOTE: The number of devices supported can be viewed using the number of viewable devices. Response timeout can be configured in serial port page under the Settings > Communication tab.

NOTE: Do not use the serial slave addresses 1 or 16 in automatic transmission mode on a daisy chain with mixed protocols. For example, a single daisy chain with some devices using PowerLogic^TM protocol and others using Modbus RTU/Jbus protocol.

The following figure shows Link150 gateway in master mode topology:

NOTE: In specific case the maximum number of slave devices can be extended to 128 devices by using repeater.

If you selected Master mode on the Serial Port page, follow the steps to set up the device list:

Step	Action	Result
1.	From the Link150 menu bar, click Settings.	Opens the Settings menu.
2.	From the Settings menu, in the Communication submenu, click Device List.	Displays the Device List page.
3.	Select the number of viewable devices (16 to 128) and click Apply Changes.	Based on the number of viewable devices selected, the number of rows in the device list page appears. NOTE: System communication degrades as the number of devices grow.
4.	Select the Protocol.	Selects the protocol of the connected device.
5.	Enter the Device Name.	Enters the name of the device.
6.	In the Local ID box, type the local ID (address) of the serial slave device.	Enters the local address of the device.
7.	Repeat steps from 4 to 6 until all of the devices are entered.	Enters all of the connected devices.
8.	Click Apply Changes.	Updates the Device List settings.

Device List Parameters for Master Mode

Parameters	Description	Settings
Number of Viewable Devices	The maximum number of viewable devices displayed on the webpage.	16, 32, 48, 64, 80, 96, 112, or 128
Protocol	Selects the protocol type.	Modbus (Factory setting) PowerLogic JBus
Device Name	Denotes the name of the slave device.	– NOTE: Device Name must be a unique value.
Local ID	The local address of the device connected to the Link150 gateway.	For serial port: 1–247 and 255 NOTE: Local ID must be a unique value.

Slave Mode Device List Setup

Serial port slave mode allows the serial Modbus master devices to access information from serial slave devices across a TCP/IP network.

The following figure shows Link150 gateway in slave mode topology:

If you selected Slave mode on the Serial Port page, follow the steps below to set up the device list:

NOTE: Before configuring the device list in slave mode the remote device IP address needs to configured in the Serial Port page

Step	Action	Result
1.	From the Link150 menu bar, click Settings.	Opens the Settings menu.
2.	From the Settings menu, in the Communication submenu, click Device List.	Displays the Device List page.
3.	Select the number of viewable devices (1 to 128), and click Apply.	Selects the number of viewable locations that can be used to define serial slave devices connected to the Link150 gateway.
4.	Select the Connection	Selects the Modbus TCP/IP address to associate with the remote ID.
5.	Enter the Device Name.	Displays the name of the device.
6.	In the Local ID box, enter the local ID (address) of the serial slave device.	Enters the address of the device that the local Modbus master device will use to access the remote device.
7.	In the Remote ID box, enter the remote ID (address) of the serial slave device.	Enters the serial slave address of the remotely connected device.
8.	Repeat steps 4 to 7 until all of the devices are entered.	Enters all of the mapping information for the Link150 gateway to communicate to the remote devices.
9.	Click Apply Changes.	Updates the Device List settings
