Receive Heartbeat
network input config sd_string("&2,i.j.k,0\x80,48") SNVT_time_sec nciSndHrtBt;
This input configuration property sets the maximum period of time that can elapse before the
functional block will automatically use the default values for the following network variables:
nv10, nviRemotePress
nv11, nviRemoteFlow
Valid range
The valid range is 0.0 to 6,553.4 sec (0.1 sec)
A value of 6,553.5 is invalid and will disable the automatic update mechanism.
A value of zero (0) will be used for the internal timer in the case where the configured value is 6,553.5
seconds (0xFFFF). The value of zero (0) disables the Receive Heartbeat mechanism.
Typical default value
The typical default value is 0.0 (no automatic update)
SCPT reference
SCPTmaxRcvTime (48)

nciControlMode
This configuration property defines the device control mode to be used for the normal operating mode
when a remote network pressure or flow sensor is not bound to the controller and the internal speed,
pressure or flow feedback signal is used by the controller.
Refer to Effective Device Control Mode (nvoEffControlMode) for details of the control modes.
Valid range
The valid range is the same as that of nvoEffControlMode.
