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, nvoLampValueFb[0] through nvoLampValueFb[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 nvoLampValueFb[0] through nvoLampValueFb[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 output network variable has been sent upon receiving a status change signal from the remote-control relay, the
heartbeat transmission timer is reset and restarts to time down.
Output Network Variable Data
Depending on the remote-control relay status, output network variables nvoLampValueFb[0] through nvoLampValueFb[7]
send the following data to the network:
nciDefaults Event-driven Transmission
(state) = 0, (value) = no effect
Enable event-driven transmission.
Output network variables nvoLampValueFb[0] through nvoLampValueFb[7] are
sent immediately when any change occurs in these values.
(factor y setting)
(state) = 1, (value) = no effect Disable event-driven transmission.
Remote-control Relay Output Network Variable
ON (state) = 1, (value) = 100.0%
OFF (state) = 0, (value) = 0.0%
