Errors When the Alert_Key Parameter Is Set to Zero (Default)

Primary Software: Driver Software>>NI-FBUS
Primary Software Version: 2.3.5
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem: Why do I receive errors when the Alert_Key parameter is set to zero (default) and what can I do to fix this?

Solution: When creating a new block in the Network Configurator, the Alert_Key parameter always defaults to 0. According to the Fieldbus specification, this is an illegal value and errors will be generated accordingly. In order to prevent these errors from appearing, it is necessary to set the Alert_Key parameter to a number greater than zero. Valid settings for the Alert_Key parameter range from 1 to 255. Typically this value is used in the host for sorting alarms.
