Continuous setting/continuous monitoring

Data specified in advance can be set and monitored continuously by setting the continuous setting execution (RY2E) and
continuous monitor execution (RY2E) in the master station to ON.
For continuous setting data, the data set for RAM writing is not stored during a power failure.
The latest data existing in LE7-40GU when the master station gives the send request can be monitored continuously.
However, regarding the update of parameters for which the monitor update cycle is specified by the setting in LE7-40GU, the
data is updated in the specified update cycle if the specified update cycle is longer than the monitor update cycle in the send
request given by the master station.
