Loading the DSB block
To load a DSB block, the PGM platform block and the Protocol Block to which the DSB is associated must be
previously loaded. However, the DSB load fails and will be canceled if any of the following errors are
encountered.
• The PGM platform is not present and loaded.
• The slave device address is not configured in the Profibus Network Configuration Tool.
For example, you enter the slave device address as 25 in the Main tab configuration form of the DSB block
but you have not defined any slave device with address 25 in the Profibus Network Configuration Tool. In
such a scenario, you cannot load the DSB block.
Loading the PIOMB block
To load a PIOMB block, you must associate the PIOMB with a PDC of the DSB. You cannot load a PIOMB
block that is not associated with a PDC.
Attention
• You can load the PIOMB block even when the CM is not active.
• Before loading the PIOMB , set the PDC Data Subscription Rate to a value that ensures process data is available at
every execution of the Control Modules containing assigned PROFIBUS I/O channels.
Loading the PBHIOMB block
To load a PBHIOMB block, you must associate the PBHIOMB to the DSB. You cannot load a PBHIOMB block
that is not associated with a PDC.
The PBHIOMB can be loaded by right-clicking the module and then click Load.
Attention
When a PBHIOMB is loaded, all PBHCHANNELs under the module are loaded automatically. A PBHCHANNEL
must be loaded individually only when the channel is created during the run time.
