7.3.7 ProSoft Configuration Builder (PCB) HSBY Option
Functionality
ProSoft Configuration Builder is required to set up, control, and identify matched
Primary/Standby HSBY PTQ-PDPMV1 module sets.
Considerations should be identified for uploading and downloading of module
configuration data as if the dual modules were a single module, whereas upon
downloading the configuration files, files are sent to both PTQ modules
automatically.
The PCB will not be required to be concerned with Primary or Standby initially.
However, the PCB will be required to know which module is Primary in order to
perform accurate online monitoring (Standby Master modules will not be
communicating with the slave devices).
A new icon is created to indicate the PROFIBUS configuration is in Hot Standby
mode. The icon is displayed as a double PTQ module as shown in the following
illustration.
