Heartbeat Transmission (Periodical Transmission)
When the input value at any input terminal does not change, this functional block sends output network variables nvoPT[0]
through nvoPT[3] repeatedly at intervals designated by nciMaxStsSendT1. When the nciMaxStsSendT1 value is 0, the
heartbeat transmission is disabled.
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.
Sampling Intervals
The configuration type of nciMinSendT1 to designate the minimum transmission interval is SNVT_elapsed_tm (day, hour,
minute, second, millisecond). When a value over 60 seconds is set, the interval is designated as 60 seconds.
