7.10.2 Functions of Turck Excom DSB
Function
• Integrates the PROFIBUS DP slave devices to the Experion.
• Reads data from field devices and writes output into field devices depending on whether the I/O module is
an input module or an output module.
• Processes extended diagnostic data and updates channel status and sends notification based on the channel
status.
• Receives data from PIOMB and sends it to the device, if the PDC is connected to a PIOMB.
• Updates the PDC states.
Data Processing
See “Data processing” on page 118.
Status Diagnostics
The status information for the input data is a single bit, and is set to "Bad" when there is a loss of
communication between the PGM and the devices. By default, the status bit for analog inputs (AI, TI, and
Counter) is always the most significant bit within the value field. Counter inputs have an additional overflow
status bit.
The digital input modules can be configured to have status for the input channel data.
The output data has no status information.
All the channels of a PDC is set "Bad" when a module error exists. The following are the possible module error
types.
• Module not inserted
• Wrong module insertion
• Module error
For Turck Excom modules, the status bit in the data word is set in the event of a module error and the input
values are provided with substitute values.
The following table lists the minimum and maximum values that can be substituted for the input values in case
of a module error.
Attention
The input values are substituted with the minimum value, maximum value, or the last good value. This substitution is
based on the selection made for the Fail-safe mode, while configuring the I/O module during field network
configuration.

The channel status of all the modules can be obtained from the extended diagnostics information.
Tip
You can view the diagnosis and extended diagnosis of the devices online. For more information, see “Viewing the
slave device diagnosis” on page 100 and “Viewing the slave device's extended diagnosis” on page 101respectively.
