Reduced logging

The ModbusE interface allows the user to reduce logging by use of the messages per interval ( /mpi ) and the log suspension interval ( /lsi ) command parameters. If reduced logging is enabled, the number of messages indicated by the messages per interval parameter is the maximum number of messages that can be logged within the log suspension interval. If /mpi is set to 15 and the /lsi is set to 10, then the interface will log a maximum of fifteen messages every ten seconds. This cycle of maximum messages within a suspension interval will repeat until either the interface terminates or reduced logging is turned off.

If either the /mpi or the /lsi startup command parameter is set, reduced logging will be enabled automatically (the /logging flag reduced will be set). If one of the parameters is set and the other is not, the other parameter will be automatically set to its default value.

If the modbus interface configurator is used to configure reduced logging, setting the reduced logging flag will enable both the messages per interval and the log suspension interval parameter values. Likewise, clearing the reduced logging flag will disable both parameter values.
