For each Controller found on an MB300 network, this Driver creates an MB300_Node.ini file on the folder specified in the Database Translation File Path option on the Masterbus 300 tab.

This INI file is used for saving information about the translation of each block name to its internal address, Logical File and Logical Record, informed by a Controller. During this Driver's start up process, it loads this file and stores in advance the address of each block, avoiding the repetition of the translation process, which can take several minutes. This INI file is a sequence of lines describing each block, and each line contains the following options:

BlockName, LF, LR, BlockType, BlockSubType, TranslationFlag

Where:

•LF: Logical File number

•LR: Logical Record number

•BlockType: A number indicating the type of a block

•BlockSubType: Used only by the GENUSD block for sub-typing

•TranslationFlag: Configure to 1 (one) if a block is already translated or configure it to 0 (zero) if a block is not translated yet. All blocks with this property set to 0 (zero) must be translated before starting any communication with them. This is performed during the first Driver's start up or until all blocks are translated

If users stop this Driver before all blocks are translated, the INI file is saved up to that moment, so that on this Driver's next start up it resumes at the first non-translated block found.
