The Allen Bradley driver provides these tag types to support communication with Allen Bradley PLC Devices:
| Icon | Tag Type | Version | Description |
|---|---|---|---|
| Allen Bradley Ethernet Channel Tag | 2.2 | An IP Address used for Allen Bradley Ethernet communication. |
| Allen Bradley Serial Channel Tag | 2.2 | A serial port used for Allen Bradley serial communications. |
| Allen Bradley PLC Tag | 2.2 | An Allen Bradley PLC Tag. |
| Allen Bradley Register Block Tag | 2.2 | A block of registers read from an Allen Bradley PLC. |
The Allen Bradley tags you configure tells the driver how to interact with Allen Bradley PLC Devices.
You can use these I/O Data Point Tags to represent individual data points in the PLC:
| Icon | Tag Type | Version | Description |
|---|---|---|---|
 | I/O Analog Data Point Tag | 3.12 | Maps an Analog Data Point Tag to an external data source. |
