Allen Bradley Driver

Introduction

The Fernhill SCADA Allen Bradley driver uses Programmable Controller Communication Commands (PCCC). These commands can be encapsulated over DF1, Ethernet/IP or CSPv4. The driver supports these different communication options:

OptionDescription
DF1 Full DuplexPoint to point serial link
DF1 Half DuplexSerial multi-drop network
Ethernet/IPEthernet communication protocol
CSPv4Legacy Ethernet communication protocol

Fernhill SCADA Allen Bradley Tags

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

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, and the relationship between those tags, provide the instructions to the Allen Bradley Driver of how to interact with Allen Bradley PLCs.

Fernhill SCADA IO Data Tags

You can use these IO Data Tags to represent individual data points in the PLC:

IconTag TypeVersionDescription
Analog Data Tag IO Analog Data Tag 3.12 Maps an analog tag to an external data source.
Digital Data Tag IO Digital Data Tag 3.12 Maps a digital tag to an external data source.
String Data Tag IO String Data Tag 3.12 Maps a string tag to an external data source.
Word Data Tag IO Word Tag 3.12 Maps a 16-bit unsigned integer tag to an external data source.
Double Word Data Tag IO Double Word Tag 3.12 Maps a 32-bit unsigned integer tag to an external data source.
