Param_1 This field contains the database address where the 63-words of response data from the
mailbox is written. Set to -1, if the data is not to be written to the database.
For this example, the command will stop and start the specified slave(s) using
Database trigger register 3199 (stop) and 3198 (start). Any nonzero value placed
in either register will trigger the command to execute. When the command has
executed, the database register will be reset to zero. Data will be read from
database register 3200 for a count of 63 words. The response will be placed at
Database address 3500 with a length of 63 words.
The following illustration shows the parameters that execute this command.
