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.
Control Information Objects Addressing
Control information objects must be configured in a database area that is
updated in the module. You must associate each information object to a
database address in the MVI56-101S module. The interpretation of the DB
Address parameter in the configuration tables depends on the ASDU configured
and the type of addressing associated with that ASDU.
