RS485 Settings

UC100 has one RS485 port for Modbus RTU device connection.

1. Connect RS485 device to RS485 port.
2. Go to “General -> RS485” to enable RS485 and configure serial port settings. Serial port settings should be the same as the RS485 terminal devices.

   Execution Interval

(ms)

| The execution interval between each Modbus channel command.

Max Resp Time (ms)

| The maximum response time that the UC100 waits for the reply to the command. If it does not get a response after the max response time, it is

determined that the command has timed out.

Max Retry Time (ms)| Set the maximum retry times after the device fails to read data from RS485 terminal devices.
Modbus RS485 bridge LoRaWAN| If this mode is enabled, the device will transmit Modbus RTU commands

from the network server to RS485 terminal devices transparently and send Modbus reply originally back to the network server.

3. Click  to add Modbus channels, then save configurations.
   Parameters| Description
   ---|---
   Channel ID| Select the channel ID you want to configure from 16 channels.
   Name| Customize the name to identify every Modbus channel.

   Quantity| Set read how many digits from starting address, it fixes to 1.
   Type| Select the data type of Modbus channels.
   Byte Order| Set the Modbus data reading order if you configure the type as Input register or holding register.

INT32/Float: ABCD, CDBA, BADC, DCBA

INT16: AB, BA

Sign| The tick indicates that the value has a plus or minus sign.
Fetch| After clicking, UC100 will send Modbus read command to test if it can read correct values.

Example: as this setting, the device will send command: 01 03 00 00 00 01 84 0A

4. Click “Fetch” to check if UC100 can read correct data from terminal devices
   
   Note: Do not click “Fetch” frequently since the response time to reply is differ for every terminal device.

IF-THEN Command

UC100 supports configuring locally IF-THEN commands to do some actions automatically evenwithout a network connection. One device can be added 16 commands at most.

1. Go to “Command” page, and click “Edit” to add commands.
   

2. Set an IF condition based on the terminal device data or UC100 device status.
   Condition| Description
   ---|---
   Channel| When UC100 device gets certain response (False, True, Above, Below, Within) in certain RS485 channel (Channel Name + Channel ID), this command is triggered.
   Is continued for : the updated value should last for some time that is longer
    | than a sole reporting interval.

Set lockout time: after the lockout time, UC100 will check if the latest RS485 response matches the condition still. 0 means this IF condition will only be

detected once.

---|---
Received a D2D control command| This only works with the LoRa D2D feature enabled. See details on chapter 4.5.
3. Set THEN action according to your request. You can add at most 3 actions
Action| Description
---|---
Send a LoRaWAN message| Send a custom message to the network server.
Restart the Device| Reboot the device.
Send a D2D control command| This only works with LoRa D2D feature enabled. See details on chapter 4.5.
Send a Modbus command via the RS485 interface| This only works with LoRa D2D feature enabled. See details on chapter 4.5.

LoRa D2D Settings

LoRa D2D protocol is developed by Milesight and used for setting up transmission amongMilesight devices without a gateway. When the LoRa D2D setting is enabled, UC100 can workasa LoRa D2D controller to send control commands to other devices or work as a LoRa D2Dagent to receive commands to trigger a reboot or message to the network server.

1. Go to “General -> Basic” page, enable LoRa D2D feature, and define a unique LoRaD2D key which is the same as LoRa D2D controller or agent devices. (Default LoRaD2DKey: 5572404C696E6B4C6F52613230313823)
   

2. Go to “LoRaWAN Settings -> Basic” to configure the RX2 datarate and RX2 frequency. WhenUC100 works as LoRa D2D controller, it will send commands as RX2 settings.
   

3. Go to “Command” page to set corresponding operations. When the RS485 channel triggers, UC100 can work as LoRa D2D controller to send a control command to control the LoRa D2D agent device. The command should be a 2-byte hexadecimal number.
   
   When UC100 receives a LoRa D2D command, it can work as a LoRa D2D agent to reboot thedevice or send Modbus command to RS485 terminal devices.
   

Maintenance
