Hey,
in order to optimize our battery usage on a remote logger, we intend to connect a RavenXT to the SW12 and power it only 10min every 4hours to allow LoggerNet to retrieve the data. Data *needs* to be updated in our database every 4hours so if the comm fails over that 10min period we are in trouble.
A more efficient and safe way to achieve it in my mind would be to configure the logger to initiate the callback and monitor for a successful data transmission. Keeping in mind that the modem should be totally powered off between communication to save as much battery as possible.
Does anyone have any experience with such a setup?
Configure LoggerNet Setup with PakBus/TCP Server root device and add your logger(s) to that setup. Make sure LoggerNet is accessible by cell modem, often customers get a public, static, IP address for their office network and forward port 6785 to their LoggerNet PC that is listening on port 6785.
Maybe something like this would get you started
Public PTemp, batt_volt
Public Handle As Long
Public Result
DataTable (Test,1,1000)
DataInterval (0,15,Sec,10)
Minimum (1,batt_volt,FP2,0,False)
Sample (1,PTemp,FP2)
EndTable
BeginProg
Scan (1,Sec,0,0)
PanelTemp (PTemp,250)
Battery (batt_volt)
CallTable Test
NextScan
SlowSequence
Scan(1,Min,0,0)
If IfTime (0,240,Min) Then SW12(1)
If IfTime (5,240,Min) Then
Handle = TCPOpen ("000.000.000.000",6785,0,30000,Handle,1)
SendVariables (Result,Handle,-1,4094,0000,0,"Public","Callback",Handle,1)
EndIf
If IfTime(10,240,Min) Then SW12(0)
NextScan
EndSequence
EndProg
