However, there is no guarantee that interference will not occur in a particular installation. If this equipment does

cause harmful interference to radio or television reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void

the user's authority to operate this equipment.

FCC Caution

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This

device may not cause harmful interference, and (2) this device must accept any interference received, including

interference that may cause undesired operation.

FCC Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This

equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

Introduction

EasyIO FS Series supports Modbus as a Master Driver. It is capable of handling the following Modbus protocols; This document is compatible for both FS Series since the hardware profile of 2 models are identical.

1. Modbus RTU Master (NO Modbus ASCII support) 2. Modbus TCP Master 3. Modbus TCP Gateway

Prerequisites 1. CPT Tool dated 10th Oct 2018 or later. Latest CPT at the time of the document is 06th Dec 2019. 2. For FS Series running v3.0b51b or later firmware is the best.

Configuring the Modbus Serial Network The architecture of the driver is a tiered, parent/child structure as indicated below. The network object can be placed anywhere in the Sedona apps. It is recommended to create a separate folder for each network to allow logical identification of each “parent” network and the associated “child” devices and points. Network

**Note** In order to configure the MODBUS driver 3 kits need to be installed. These kits are included in the release package. Installation of the kits is shown in the following steps

1. easyioFGModbus – 1.0.45.51.28 or higher 2. easyioFGDriver - 1.0.45.51.3 or higher 3. easyioFGSerial – 1.0.45.51.2 or higher

Step 1 Connect to the controller with CPT Tool.

Default login credentials are as below;

IP address : 192.168.10.12 Username : admin Password :<no password>


8

Add the kits to the controller by navigating to manage kits and install easyioFGModbus, easyioFGDriver and easyioFGSerial kit into your controller

Step 2 Go to the service folder by double clicking it. It will display the service folder objects. If the SerialService object is not present in the folder, drag and drop the service object in to the service folder from the easyioFGSerial kits library.

Step 3 From the easyioFGModbus kit selections “drag & drop” the ModbusSerialNetwork object into your App.

The object can be placed anywhere, directly in the tree, in the EasyIO folder, or in a new folder if desired.

In this case, the object will be dropped into a new folder named “Modbus”.

It is possible to rename the ModbusSerialNetwork object. In this case the ModbusSerialNetwork object has been renamed as RTUNet.

Step 4 Double click the ModbusSerialNetwork object to access the object property sheet. You will need to configure the serial network communications parameters according to the requirements Modbus device. Enable the network. **Tech Tip: - Please note that only Port 2(D2+ & D2- Terminals) on the FG Series controller can be used**

Step 5 Select and drag a ModbusSerialDevice object from the EasyIOFGModbus kit Sedona palette and Drop it under the Network object. The Slave device must be a “child” of the Network object. Renaming of the device object is possible.


10

Step 6 Drop the required MODBUS register type object under the Device Object. The Register object must be a “child” of the “parent” Device Object. The use of folders within the Device Object is possible. It is recommended to use folders within the device object for better data management.

Step 7 Set the register address for the desired point under the “address” property of the desired object type. Enable the point by setting the register “enable” property “true”. **Tech Tip: -The only MODBUS register addressing format supported by the EasyIOFGModbus kit is “Decimal” format addressing. No HEX format or MODBUS format addressing is allowed. If the MODBUS address in the 3rd party device is supplied in either HEX or MODBUS format please convert it to Decimal format and enter the Decimal equivalent in the “address” property of the associated register.** In the example below, the address 30001 is Modbus format which is equivalent to decimal address 1.

Step 8 By default all “writable” registers have a “Read Write” property to enable the “write” function. If the register is a “ReadWrite” register and writing is required, enable the write ability by setting the “Read Write” property to “true” as shown below.

Step 2 After installation, choose easyioFGModbus from the Sedona Palette of Sedona Workbench or CPT Tool.

From the easyioFGModbus kit selections “drag & drop” the ModbusTCPNetwork object into your App.



It is possible to rename the ModbusTCPNetwork object. In this case the ModbusTCPNetwork object has been

renamed as TCPNet.

Step 3 Double click the ModbusTCPNetwork object to access the object property sheet. Enable the network by setting the Enable property to “true”.

Step 4 Select and drag a ModbusTCPDevice object from the EasyIOFGModbus kit Sedona palette and drop it under the Network object. The TCP device must be a “child” of the “parent” TCPNet Network object. Renaming of the device object is possible.
