Ethernet/Ip
The Ethernet/IP Device Driver allows Iotellect Server to communicate with devices supporting Ethernet/IP Protocol. These devices may be connected to the system and, like with all other types of devices, their data is converted into a unified form, so they can be accessed from different Iotellect facilities. See Devices article for more information about the "normalized" representation of devices in Iotellect.
Ethernet/IP driver uses unconnected explicit messages (UCMM) to a service of class on the field device.
Driver Information
Driver Plugin ID: | com.tibbo.linkserver.plugin.device.ethernet-ip |
Global Settings
None defined.
User Level Settings
None defined.
Device Account Properties
Connection Properties
Connection settings define how Iotellect Server communicates with a certain Ethernet/IP device. These settings may be accessed using the Edit Device Properties action of Device Context. The following connection properties are available:
Property | Description |
IP Address or Host Name | Address of Ethernet/IP device. |
Port | Device port. |
Slot | Device slot. |
Device Objects
This property contains a list of Ethernet/IP device objects (tags) that are accessed and managed by Iotellect. Once a new Ethernet/IP device is added, one or more objects have to be configured to make device data available for the system. Each Ethernet/IP object is represented by a single variable of Device Context.
Setting | Description | |
Name | Object name. | |
Description | Object description. | |
Object Format | Defines format of the Object: | |
Property | Description | |
|---|---|---|
Name | Field name. | |
Description | Textual field description. | |
Type | Defines how to interpret value of one or more adjacent Objects. See type conversion section for details. | |
Writable | Flag indicates that object variable is writable. | |
Class | This is the CIP class to which the message will be sent. The class number can be found in the documentation of the field device. | |
Instance | This is the CIP class instance to which the message will be sent. The class instance number can be found in the documentation of the field device. Using instance number zero will access the services of the class, not a specific instance of the class. | |
Attribute | This is the attribute of the CIP class that the service will operate on. Some services require an attribute and some do not. | |
Device Assets
Assets are not supported by the driver.
Device Settings
Ethernet/IP device driver creates one Device setting variable per device register.
Type Conversion
The following table shows how Ethernet/IP Objects are converted to Device context variables.
Type | Bytes per Value | Iotellect Server Variable Format |
BOOL | 1 | Readable/Writable, 1 Column of type Boolean |
SINT | 1 | Readable/Writable, 1 Column of type Integer |
INT | 2 | Readable/Writable, 1 Column of type Integer |
DINT | 4 | Readable/Writable, 1 Column of type Integer |
SHORT_STRING | 1 + n (first byte indicates length) | Readable/Writable, 1 Column of type String |
STRING | 2 + n (first byte indicates length) | Readable/Writable, 1 Column of type String |
Device Operations
No operations provided by the driver.
Device Events
No events provided by the driver.
Connection Handling
This driver makes the device Online if:
TCP connection with the Device was successfully established
Synchronization Details
Synchronization between Iotellect Server and Ethernet/IP device includes the following steps:
Creating a Settings Cache according to the Device Objects list. Each variable is used to access a single Ethernet/IP device object.
Reading Ethernet/IP register values and storing these values in settings cache.
