5.2.1
Validity Flag (Pn and Pn+12)
The first P-table entry of each module’s configuration data contains a validity flag. Its
function is to prevent an uninitialised ‘P’-table from being used as configuration
parameters. The user must insert the hexadecimal value @4801 (module #1) or
@4802 (module #2) into the relevant table entry to signify that the module
configuration data is valid.
The insertion of any other value into the table entry renders inactive the associated
Fieldbus module.
