Fernhill SCADA Allen Bradley Tags

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

IconTag TypeVersionDescription
Channel IconAllen Bradley Ethernet Channel Tag2.2An IP Address used for Allen Bradley Ethernet communication.
Channel IconAllen Bradley Serial Channel Tag2.2A serial port used for Allen Bradley serial communications.
PLC TagAllen Bradley PLC Tag2.2An Allen Bradley PLC Tag.
Register Block TagAllen Bradley Register Block Tag2.2A 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.
