Manual Integration Of A Field Device - Siemens Simatic CFU Commissioning Manual

A field device connected to the service port is automatically detected if it was last in operation
on this CFU at one of the other fieldbus ports.
● It is automatically routed (mapped) to the original fieldbus connection of the CFU.
● The original fieldbus connection is deactivated when the field device is detected at the
service port until you disconnect the field device from the service port or deactivate the
service port.
● Current and voltage of the field device connected to the service port are not monitored.
Behavior of a field device at the service port
Process operation
If the field device is connected to the service port, values for the field device continue to be
transferred to the process.
Make sure that the field device is not used in the process mode at the time of calibration.
Additional information
You can find information on the use of the service interface in the section "Using service
interface (Page 106)".

Manual integration of a field device

The CFU PA attempts to read the supported IO from the field device.
If the attempt of the CFU to read the IOs from the field device fails, you can manually connect
the field device to the CFU.
Note
Manual integration enabled for a fieldbus connection
When manual integration is enabled for a fieldbus connection, the following functions are
disabled for this fieldbus connection:
● Automatic import of the identification numbers (IOs) from the field device by the CFU PA
● Automatic assignment of the identification numbers (IOs) by the CFU PA in the field device
Basic procedure
1. Activate the "Manual field device integration" parameter in HW Config for the fieldbus
connection of the CFU.
You can find information on this in section "Assigning parameters to the PA master
(parameter overview - FB M) (Page 80)".
2. Set the IO in the field device such that it matches the configuration.
