8502-BI-DP Bus interface modules GE

The 8502 supports parameterisation from the Profibus master. This configures on a “per module” basis, i.e. all the channels on a single module carry the same configuration. The configuration is created in Profibus configurator using details provided in a GSD file. This method is fast and enables a configuration to be built based upon “logical” modules which represent the physical modules. Modules are added one at a time to the configuration and parameters are chosen to apply to all the channels of the module. Logical modules can be selected to provide HART status and process variables in the Profibus-DP cyclic input telegram. In addition, for applications where access to many HART variables is required, the HART “mailbox” can be used. This technique collects HART variable as they are required; saving space in telegrams that are sometimes overworked with data. This method is available only when using parameterisation.
The configuration is passed down from the Profibus master to the BIM at the start of the session. If the system is stopped and re-started, the configuration file is re-transmitted to the BIM.
