Event-driven Transmission
Event-driven transmission is enabled or disabled by setting the nciDefaults state as shown below.
Whether event-driven transmission is enabled or not, nvoCount[0] through nvoCount[7] are sent when receiving a request
(polling) from the network or at regular intervals designated by nciMaxStsSendT1.
Heartbeat Transmission (Periodical Transmission)
This functional block sends nvoCount[0] through nvoCount[7] repeatedly at intervals designated by nciMaxStsSendT1.
The configuration type of nciMaxStsSendT1 is SNVT_elapsed_tm (day, hour, minute, second, millisecond). When a value
over 12 hours is set, the interval is designated as 12 hours 00 minutes 00 seconds. The millisecond value has no effect.
When the nciMaxStsSendT1 value is 0, the heartbeat transmission is disabled.
Sampling Intervals
The nciMinSendT1 designates the minimum interval of sending nvoCount[0] through nvoCount[7].
The configuration type of nciMinSendT1 is SNVT_elapsed_tm (day, hour, minute, second, millisecond). When a value
over 12 hours is set, the interval is designated as 12 hours 00 minutes 00 seconds. The millisecond value has no effect.
When the nciMinSendT1 value is 0, the minimum transmission interval is disabled.
nciDefaults Event-driven Transmission
(state) = 1, (value) = no effect
Enable event-driven transmission.
Output network variables nvoCount[0] through nvoCount[7] are sent immediately
when any change occurs in these values.
(factor y setting)
(state) = 0, (value) = no effect Disable event-driven transmission.
