4. Configure the input and output formats for the slot configuration.

In this example, the setpoint sent to the valve positioner is a real value with

a 1-byte status. The actual position that the valve positioner returns is also

a real value with a 1-byte status, with an added 1 byte with status and

discrete position.

5. Use the AOP to download the configuration to the linking device. A real

value can now be written into the output PV tag for that field device in the

Studio 5000 Logix Designer application (as shown in the following

figure).

IMPORTANT

See the documentation for the valve positioner to verify the correct

data format for each option.

TIP

See example code CN2PAR_FieldDevice_Outputs.ACD.

IMPORTANT

Send a Good/Valid PV status to the field device output. See the field device user

manual for the needed status values. Typically, if you send a PVStatus value of

0x80 (-128), the field device accepts the position that is given. If you do not

send a Good/Valid PV status to the field device output, the valve postioner

ignores the position that is supplied and returns to a Safe state.
