C&H DR-100-24 Switching power supply module

Transmission These variables are transmitted immediately when its value has been changed by a higher rate than the configured "send on delta" (in the case of the totalizer, “send on delta” has a default value of 5 counts). These variables are also transmitted as a heartbeat output on a regular basis as dictated by the maximum send time (nciSndHrtBt) (default = 0 = disabled) configuration variable. Default Service Type The default service type of these variables is unacknowledged.Totalizer Count – nvoDiCount[ ] This network variable output indicates the total number of transitions from 0 to 1 since the last reset due to power-up or network reset.

XFL(R)824 Relay Output Module

 One instance of the LONMARK open-loop sensor object has been assigned per input of the XFL824/XFLR824 Relay Output Module. Each output object has its own configuration properties, except for heartbeat configuration, which will be shared among all objects.Start-up Behavior At start-up, i.e., power-up or reset, all nvi's will be initialized with INVALID, leading the actuator to drive to the configured safety position after 1 minute. Receive Heartbeat The default configuration for “Receive Heartbeat” is 300 sec. If no nvi update is received during this time, the field devices will go to their configured safety positions.
