The following sections describe the address syntax used with each
category of IO Driver.

Hardware Specific Drivers

The hardware IO drivers are used to access digital I/O states and
process variable values. The specific IO value is addressed by
number. Table 12.12 lists the hardware specific drivers and the
corresponding database offset ranges.

Table 12.12 Addresses Used for Hardware

Specific Drivers

Parameter Specific Drivers

The parameter specific IO Drivers (Setpoint, Soft_Input, Soft_Bool,
and Soft_Int) are used to read or set values for specific parameters.
The specific parameter value is addressed with its database offset.

Table 12.13

lists the parameter specific drivers and the

corresponding database offset ranges.

Table 12.13 Addresses Used with Parameter

Specific IO Drivers

Database Driver

The Database IO Driver is used to examine or set values for any
closed-loop control parameter such as Control Mode that is not
supported by one of the other drivers. The Database driver allows
access to all controller parameters. Other drivers are provided for
faster access to specific parameters. Of course, controller parameters
that are read-only cannot be adjusted. The specific parameter value
is addressed with the parameter number and its database offset. See

Table 12.14 on page 210

for a description of this syntax.
