GE Fanuc PLC Data Address

Introduction

Data in GE Fanuc PLC Devices is stored in different locations depending on the intended use of the data. For example there are separate locations for:

Discrete Inputs
Discrete Outputs
Analog Inputs
Analog Outputs
Registers

The GE Fanuc PLC Data Address is a string that defines the location of data in a GE Fanuc PLC. It consists of device type letters, followed by decimal digits:

Device Type	Format	Notes
Discrete Input	%Innnn
Discrete Output	%Qnnnn
Discrete Internal	%Mnnnn
Analog Input	%AInnnn
Analog Output	%AQnnnn
Register	%Rnnnn

Note: The numbers in GE Fanuc Data Addresses are 1-based.

Where Used

The GE Fanuc PLC Data Address is used in these contexts:

In the IOItemName property of an I/O Analog Data Point Tag when the tag is associated with a GE Fanuc PLC.
In the IOItemName property of a I/O Digital Data Point Tag when the tag is associated with a GE Fanuc PLC.
In the IOItemName property of a I/O Word Data Point Tag when the tag is associated with a GE Fanuc PLC.
In the IOItemName property of a I/O Double Word Data Point Tag when the tag is associated with a GE Fanuc PLC.
In the IOItemName property of a I/O Long Word Data Point Tag when the tag is associated with a GE Fanuc PLC.
In the DataAddress parameter of the DirectWriteBit Tag Command when used with a GE Fanuc PLC.
In the DataAddress parameter of the DirectWriteWord Tag Command when used with a GE Fanuc PLC.

Data Address Editor

The Data Address Editor provides a convenient tool to build GE Fanuc Data Address strings.
