CONNECTIONS

Modbus Connection Data

Description

ConnectionName¹⁾

Name of the Modbus connection instance.
NOTE: The Importer will reject this connection entry if this field is empty.

ConnectionDescription¹⁾

Description of the Modbus connection instance. The same description will be set for all the available languages of the project.
NOTE: The Importer will reject this connection entry if this field is empty.

SlaveID¹⁾

Unique number given to the connection, if it is connected to the gateway using the same IP address and port. This field must be numeric and greater than 0.
NOTE: The Importer will reject this connection entry if this field is empty.

IP_Address¹⁾

IP address of the connection connected to a network. This field should be in the format xxx.xxx.xxx.xxx, where x is numeric. Valid values are 0 through 255. After the import, you can change this field from the Modbus interface workspace.
See Points to Consider Before Importing the CSV File , which explains the significance of duplicate IP addresses across multiple interfaces under the same network.
NOTE: The Importer will reject this connection entry if this field is empty or if the format of the IP address is wrong.
After the import, you can edit the IP address in the Communication Interface expander.

Port¹⁾

TCP port number to be assigned to the connection. Valid values are 0 through 65535.
NOTE: If this field is empty, then Modbus Importer will set the value to 502.

LittleEndian

Specify the Endianity of the Modbus device.
Default value = True
True: If the value is set to True, then Endianity of the device is set to Little Endian.
False: If the value is set to False, then the Endianity of the device is set to Big Endian.
Blank or Invalid: If no value is specified or any non-boolean value is specified, then the Modbus driver will read the Endianity value from the project config file.

ByteSwap

Specify the ByteSwap of the Modbus device.
Default value = False
True: If the value is set to True, then device is set to Byte Swap.
False: If the value is set to False, then device is set to Word Swap.
Blank or Invalid: If no value is specified or any non-boolean value is specified, then the Modbus driver will read the Byte Swap value as False.

Active

Specify if a connection with the device is to be established. It can have either of the following two values:
True: Connection with the device will be established.

False: No connection with the device will be established.

Default value is True

Offset

This data point element allows to define the offset. Default value is 0

FrameCoding

Specify the type of frame coding supported by the device. In general the following types of frame coding is supported, ASCII, RTU, TCP.

The exact value supported by the device is available in the device manual.

The default value is TCP.

Alias

Alias assigned to the connection.

FunctionName

Name of the function to which the connection is associated with.

DisciplineID

Discipline to be associated with the connection.

SubdisciplineID

Subdiscipline to be associated with the connection.

TypeID

Type to be associated with the connection.

SubtypeID

Subtype to be associated with the connection.
