Fernhill SCADA Allen Bradley Tags

The Allen Bradley driver provides these tag types to support communication with Allen Bradley PLC Devices:

IconTag TypeVersionDescription
Channel Icon Allen Bradley Ethernet Channel Tag 2.2 An IP Address used for Allen Bradley Ethernet communication.
Channel Icon Allen Bradley Serial Channel Tag 2.2 A serial port used for Allen Bradley serial communications.
PLC Tag Allen Bradley PLC Tag 2.2 An Allen Bradley PLC Tag.
Register Block 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.
