Transmission/Updates These variables are transmitted immediately when their value has been changed by a higher rate than the configured "send on delta" (default: 0.3 K). These variables are also transmitted as heartbeat output (default: 60 sec) on a regular basis as dictated by the maximum send time (nciSndHrtBt) configuration variable.

Temperature Sensor Output – nvoAiTempP[ ] If configured for temperature sensor input (but not from PT1000-2 temperature sensors), this network variable output represents the temperature for the appropriate input. Range: see Table 44 and Table 45 on page 40. Default Value The default value is set after power-up or reset and remains until the module has measured a valid value. nvoAiTempP = INVALID = 0x7FFF (= 327.67 °C) Slow Digital Input – nvoAiSwitch[ ] This network variable output represents a slow digital input connected to the universal input terminals.If configured for temperature sensor input (from PT1000-2 temperature sensors, only), this network variable output represents the temperature for the appropriate input. Range: see Table 44 and Table 45 on page 40.

Receive Heartbeat 

The default configuration for “Receive Heartbeat” is 300 sec. If no nvi update is received during this time, the actuators will go to their configured safety positions. Start-up Behavior At start-up, i.e., power-up or reset, all nvi's will be initialized with INVALID, and after 1 minute, the actuators will go to their configured safety positions.Default Value nvoAoValuePct = INVALID = 0x7FFF (=163.835%) This will cause the actuator to adopt a predefined position defined for failure behavior This value represents the current status of the analog output including feedback related to manual override initiated from the manual override. This is typically used for monitoring purposes at a supervisory station or for diagnostic purposes. This variable is transmitted immediately when the corresponding network input variable has changed more than 1% or immediately as an answer to an nviAoValuePct[ ] or nviAoSwitch[ ] update.

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.
