Refer to the following parameter to configure the select/operate timeout period.
After the module receives the SELECT operation it will wait for this period of time
for the EXECUTE operation. If the module does not receive an EXECUTE
operation within this period of time it will require another SELECT operation
before the EXECUTE operation.
Command Points Addressing
Command points must be configured in a database area that is updated in the
module. You must associate each point to a database address in the PTQ-104S
module. 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.
