PPC-2000 IO Drivers
IO Driver Choice
The IO Driver allows the logic program to examine or set an
I/O value or other value stored in the database. Choose the
appropriate driver for the value which you want to access.
Table 12.4 describes what data can be accessed with each IO
Driver.
Table 12.4 Data Accessed by the IO Drivers
IO Physical Addresses
The IO Physical Address syntax depends on the IO Driver.

IO Driver Data Accessed
Processor_2010
Digital input and output states and count and
frequency input values on a PPC-2010 Proces-
sor module.
Analog_202x
Analog input values on any PPC-202x series
Analog Input module.
Encoder_Analog_2030
Count and frequency input values and analog
output values on a PPC-2030 Encoder In Ana-
log Out module.
Digital_IO_2040
Digital input and output states and count and
frequency input values on a PPC-2040 Digital
I/O module.
Analog_Out_205x
Analog output values on any PPC-205x Analog
Out module.
Digital_Out_206x
Digital output states on any PPC-206x Digital
Out module.
Digital_In_207x
Digital input states on any PPC-207x Digital In
module.
Setpoint
The setpoint of any of the closed-loop control
channels.
Soft_Input
The value of any of the Soft Inputs. Typically
used for a logic program to output a value to the
input of a closed-loop control channel.
Soft_Bool
The value of any Soft Bool register. Typically
used to exchange information between a logic
program and an HMI program or operator inter-
face panel.
Soft_Int
The value of any Soft Int register. Typically used
to exchange information between a logic pro-
gram and an HMI program or operator interface
panel.
Database
The value of any closed-loop control parameter
that is not supported by another IO Driver.
