9.5 Assigning a PROFIBUS Channel to PIOMB
After you assign a PDC to a PIOMB, you must assign a PROFIBUS channel to the Control Module containing
the C300CEE. You must perform this to view the data of the input or the output channel.
The following are the types of PROFIBUS I/O channel blocks that are available and you must select the
appropriate channel block based on the channel type.
PbAiChannel - If the channel type is analog input channel.
PbDiChannel - If the channel type is digital input channel.
PbAoChannel - If the channel type is analog output channel.
PbDoChannel - If the channel type is digital output channel.
For example, if the channel type of a PDC is Digital input (DI), you must drag-and-drop the PBDICHANNEL
from the PGM_IF library into the Control Module containing the CEE.
Perform the following steps to assign a PROFIBUS channel to a PIOMB
Drag-and-drop the appropriate PROFIBUS I/O channel block from the PGM_IF library to the Control
Module containing the C300 Controller.
Double-click the PROFIBUS I/O channel block.
The PROFIBUS I/O channel block configuration form appears.
In the Module Name list, select the PIOMB associated with this channel block.
In the Module Type list, select the module type of this channel.
The number of channels that can be assigned to this block and the channel names appear under the Module
Select the appropriate channel number to which you must assign the channel block.
