• With R410, you can modify the values of the following parameters 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.
– Number of Channels (NUMCHANNEL) - You can increase or decrease the Number of Channels
parameter value. There is no restriction on increasing the number of channels. However, if you want to
decrease the number of channels, you can decrease the number only until the last assigned channel
number. For example, consider a scenario where you have entered the number of channels of a PDC as
10. However, you have assigned only 6 channels (channel 0 through channel 5) to the PROFIBUS
channels. In this scenario, you can reduce the Number of Channels value to 6. If you try to reduce the
Number of Channels value to 5 or less an error message appears.
– Channel Description (CHDESCRIPTION)
– Channel Type (CHANNELTYPE) - You can modify the Channel Type of a channel only if it that
particular channel is not associated with any PROFIBUS channel.
– Channel Data Type (CHANNELDATATYPE) - You can modify the Channel Data Type for both used
and unused channels. However, you must ensure that while modifying the channel data type for analog/
numeric channels, you must not select Boolean data type. Also, for digital channels you must only select
Boolean data type.
– Channel Low Range (CHLOWRANGE)
– Channel High Range (CHHIGHRANGE)
– Channel Data Offset (CHDATAOFFSET)
– Channel Bit Offset (CHBITOFFSET)
7.16.3 Generic DSB for PA devices (GENPADSB and GENPAGWDSB) specific PDC configuration
guidelines
The following list summarizes the GENPADSB and GENPAGWDSB specific PDC configuration guidelines
that you must remember while configuring the GENPADSB and GENPAGWDSB.
• The number of PDCs supported by GENPADSB is 8 and GENPAGWDSB is 64.
• In the
PA Status Usage
column, select the appropriate option to define how the data status is used by these
blocks. Based on the option selected in the
PA Status Usage
column, the channel status is updated in the
Status
column and the
PA Status
column.
The following table summarizes the options that are available for the input/output channels and a brief
description of each option.

– For input channels, when you select this option, irrespective of the channel’s actual
state, the channel’s

column always displays the status as
Good_NonCascade
and the
PA Status
column displays the value
Not Applicable
.
– For output channels, the channel status is always set to
