7.16.5 Siemens AS-I Link DSB specific PDC configuration guidelines

The following list summarizes the Siemens AS-I Link DSB specific PDC configuration guidelines that you
must remember while configuring the Siemens AS-I Link DSB PDC.
• The number of PDCs supported by the Siemens AS-I Link DSB is 16.
• The PDC types are mapped to the AS-i Slave devices.
• This DSB supports only the DI/DO channels.
• If you have configured a PDC with a net tag that maps to the data module on the second AS-i Segment,
select Segment 2 in the ASISEGMENT column.
– The AS-I segment column appears only while configuring the Siemens AS-i Link DSB for the AS-i Link
Advanced . This is because only AS-i Link Advanced supports two AS-I segments.
– The AS-i Segment (ASISEGMENT) parameter indicates the segment to which the PDC is configured.
This parameter can be used to identify whether the slave device is configured for Segment 1 or Segment
2. This parameter is applicable only to the Siemens AS-i Link DSB.
– It is an assumption that the configured data module for segment 2 must be in slot 2, and the configured
data module for segment 1 must be slot 1.
• The net tag associated with the PDCs types must map to the 4 bytes that covers the 7 or 8 slave devices
being referenced. For more information on the PDC types of the Siemens AS-I Link DSB, refer to the
PROFIBUS Gateway Module Parameter Reference Guide.
• In the Number of Channels column, the number of channels are automatically updated based on the PDC
type. The "Slave 1-7 inputs" and "Slave 1-7 outputs" PDC types have 28 channels. The other PDC types
have 32 channels which are grouped as four channels for each slave device.
• In the Channel Number column, the channel number is automatically updated based on the number of
channels configured for the selected module.
For example, if the number of channels configured for a module is 4, then this column lists the channel
numbers as 0, 1, 2, and 3.
• In the Channel Type , the channel type is automatically selected based on the PDC type.
• In the Channel Data Type , the channel data type is always "Boolean" as this DSB supports only the DI and
DO channels.
• The Channel Data Offset column is not applicable to the Siemens AS-i Link DSB.
• The Bit Offset column is not applicable to the Siemens AS-i Link DSB.
• The Low Range column is not applicable to the Siemens AS-i Link DSB as this DSB does not support
analog channels.
• The High Range column is not applicable to the Siemens AS-i Link DSB as this DSB does not support
analog channels.
• With R410, you can modify the value of the following parameter even after a PDC is associated and
connected to a PIOMB. However, you must ensure that you reload both the DSB and the PIOMB after
modifying the parameter value. If you do not reload both the DSB and the PIOMB, there may be a break in
the connection between the DSB and the PIOMB.

7.16.6 Siemens ET200M DSB specific PDC configuration guidelines

The following list summarizes the Siemens ET200M DSB specific PDC configuration guidelines that you must
remember while configuring the Siemens ET200M DSB PDC.
• The number of PDCs supported by the Siemens ET200M DSB is 16.
• The PDC configuration must be done through the IOM configuration tab.
• In the Number of Channel column, you must enter the number of channels manually.
