3. Select Installation Folder and then click "Next" to continue.

4. Click "Install" on the Ready to Install screen to continue.

5. Installation completed, click "Finish" button to exit the Setup Wizard.

Configuration

1. Open File Explorer and change target folder to the Modbus Service installation folder.

2. Open and edit the file Mobus_Handler.ini

2.1 Give a Name for the platform.

2.2 Set the Protocol.

For the modbus TCP devices:

Protocol=Modbus_TCP

ClientIP=(IP address of Modbus TCP devices)

ClientPort=(Port of Modbus TCP devices)  

Example:

[Platform]
Name=WISE-4012E
Protocol=Modbus_TCP
ClientIP=127.0.0.1
ClientPort=502

Interval=3
#Interval: The time delay between two modbus access round in second.
Delay=0
#Delay: The time delay between two modbus access in millisecond.
#Delay=0 means no delay.
Log=0

For the modbus RTU devices:

Protocol=Modbus_RTU

SlavePort=(The serial port's device node of the gateway which connect to Modbus RTU devices)

Baud=(The baud rate of the serial port)

Parity=(The parity of the serial port)

DataBits=(The data bits of the serial port)              

StopBits=(The stop bits of the serial port) 

Example:

[Platform]
Name=EKI-XXXX
Protocol=Modbus_RTU
SlavePort=COM1
Baud=19200
Parity=None
DataBits=8
StopBits=1

Interval=3
#Interval: The time delay between two modbus access round in second.
Delay=0
#Delay: The time delay between two modbus access in millisecond.
#Delay=0 means no delay.
Log=0

2.3 Set the number of modbus devices and device detail information file.

Device0 Example:

[DeviceInfo]
Name=Modbus_Device0

# For Modbus_TCP
UnitID=1

# For Modbus_RTU
#SlaveID=1

[Coils]
numberOfB=3
B0=0,LED0
B1=1,LED1
B2=2,LED2

Device1 Example:

[DeviceInfo]
Name=Modbus_Device1

# For Modbus_TCP
UnitID=2

# For Modbus_RTU
#SlaveID=2

[Discrete Inputs]
numberOfIB=3
IB0=0,Switch0
IB1=1,Switch1
IB2=2,Switch2

EdgeSense Linux Docker version

How to config Modbus Service and Restart Service

$cd ${Installed path}/Installer/packages/Plugins/docker-edgesense-image-x86/EdgeSense/EService-Modbus/config
$sudo vim Modbus_Handler.ini
$sudo docker restart service-modbus

Application Case

ADAM-4117 8-channel Analog Input Module

1. H.W. Environment & Configuration

2. Setup Modbus register from ADAM utility: AdamApax .NET Utility

2.1 Download AdamApax .NET Utility from URL http://support.advantech.com/Support/DownloadSRDetail_New.aspx?SR_ID=1-2AKUDB&Doc_Source=Download and install it to your Gateway.

2.2 Launch AdamApax .NET Utility, select COM port which ADAM module is connected, right click on the COM port you selected and click "Search Device" to detect your ADAM-4117.

2.3 After ADAM-4117 appeared, click on it to check its settings or change the default settings for your H.W. configuration.

3. Gateway Modbus_Handler configuration

3.1 Edit Modbus_Handler.ini for the ADAM's configuration.

[Platform]
Interval=1
#Interval: The time delay between two modbus access round in second. 
Delay=0
#Delay: The time delay between two modbus access in millisecond.
#Delay=0 means no delay.
Log=0

Name=ADAM-4117
Protocol=Modbus_RTU
SlavePort=COM1
Baud=9600
Parity=None
DataBits=8
StopBits=1

[Devices]
numberOfDevices=1
Device0=Modbus_Device0.ini

#DeviceN: Modbus device files with detail register address mapping 

3.2 Edit Modbus_Device0.ini for ADAM-4117 modbus location configuration.

[DeviceInfo]
# For Modbus_TCP
#UnitID=1
# For Modbus_RTU
SlaveID=1

[Holding Registers]
numberOfR=3
R0=0,Vin0,-10,10,1,V,0,""
R1=1,Vin1,-10,10,1,V,0,""
R2=2,Vin2,-10,10,1,V,0,""
