Use the
Select/Operate Timeout
parameter to configure the select/operate timeout
period. After the gateway receives the SELECT command it will wait for this period
of time to receive the EXECUTE command for the same point address. If the
gateway does not receive an EXECUTE command within this period of time, it will
require another SELECT operation before the EXECUTE operation will be accepted
and acted upon.
3.4.2 Command
Points
Addressing
Command points must be configured in a database area that is updated in the
gateway memory database. You must associate each point to a database address in
the 104S gateway. The interpretation of the
DB address
parameter in the
configuration tables depends on the point type configured and the type of addressing
associated with that point type.
