Hi there,
i'm facing some issues with FTPClient command in CR300 logger that seems to be causing logger watchdog errors.
My requirements are:
- Must read 5 analog ports and store data at 1hz
- Must send it over GPRS to my FTP server
- i need to add a "ID,PASS" string on the first line of each file
- The server if monitoring and dealing with the files (reading and moving it)
The datatable is simple:
DataTable(Dados,True,-1) DataInterval(0,1,Sec,10) Sample(1,WindSpeed,FP2) Sample(1,WindDir,FP2) Sample(1,Temperature,FP2) Sample(1,RH,FP2) Sample(1,Barometro,IEEE4) Sample(1,BattV,FP2) EndTable
At Begining of the program, it creates a 'temp.dat' file in CPU and add ID,PASS\r\n in the first line:
BeginProg
SW12(0) ' Turn on gprs modem
Netstat = PPPOpen
' Create file with ID,PASS
Fhandle = FileOpen("CPU:temp.dat","W",0)
FileWrite(Fhandle,ID & CHR(44) & PASS & CHR(10),0)
FileClose(Fhandle)
The main scan runs at 2Hz, reads the ports and call Dados table:
Scan(500,mSec,1,0) Battery(BattV) PanelTemp(PTemp_C,400)
CurrentSE(WindSpeed,1,mV2500,1,False,10000,60,3.75,-15) If WindSpeed < 0 Then WindSpeed = 0 EndIf CurrentSE(WindDir,1,mV2500,2,False,10000,60,22.4375,-89.75) If WindDir < 0 Then WindDir = 0 EndIf VoltSe(Temperature,1,mV2500,3,False,10000,60,1,0) Temperature = 0.1*Temperature-40 VoltSe(RH,1,mV2500,4,False,10000,60,1,0) RH = RH*0.1 VoltSe(Barometro,1,mv2500,5,False,500,60,0.4,260) CallTable Dados
NextScan
Then i tried to send the data:
- First send the 'temp.dat' file and rename it to 'timestamp.temp' in server
- If the file is created, then append up to "RecMaximo" (=1200 at now) to the ftp file 'timestamp.temp'
- If everything is OK, rename it to 'timestamp.dat' to be processed by the server
- If not, try delete it
SlowSequence
Scan(10,Min,0,0)
FileName = RDir & PFile & Public.Timestamp(5,1) & PExt
FTPSucesso = FTPClient (Host,User,Pass,"CPU:temp.dat",FileName & ".temp",9,,,,,10000)
If FTPSucesso Then 'FTP file created
FTPDados = FTPClient (Host,User,Pass,"Dados",FileName & ".temp",9,0,RecMaximo,Sec,-1013,75000)
If FTPDados = -1 Then ' Send data OK
FTPSucesso = FTPClient (Host,User,Pass,FileName & ".temp",FileName,5,,,,,10000)
EndIf
If FTPDados = -2 Then 'Trying to delete temp file if send fail (possibly corruped data on file)
FTPSucesso = FTPClient (Host,User,Pass,"",FileName & ".temp",4,,,,,10000)
EndIf
EndIf
NextScan
Vars to be able to compile if you want:
Public BattV Public PTemp_C Public WindSpeed Public WindDir Public Temperature Public RH Public Barometro Public RecMaximo = 1200 Const PASS = "NGFKVM" Const ID = "CAS0232" Const Host = "ftp.server.com.br" Const User = "ftpuser" Const Pass = "ftppassword" Const RDir = "/directory/" Const PFile = "file_" Const PExt = ".dat" Public Netstat As String *500 Public Fhandle As Long Public FTPSucesso As Boolean Public FTPDados Public FileName As String * 200
As you can see, i don't have any control over the data sended by FTP, it all being done by the FTPClient.
This code is running but it's not reliable, some problems that i'm facing with:
- It runs flawless for days, then it stops complety, i need to restart the program, logger still running, just fails every FTP attempt
- Sometimes Logger restarts with watchdog error, all CPU: Memory are the Fully used, no free space anymore, it still logging data but i need to format the memory to logger start to send data again.
The datatable data interval is directly related to the frequency of fails, so seems to be some internal data management problem in FTPClient().
Any ideas? I have a very reliable program running on CR800 logger, but uses somes functions that CR300 don't support..
What is the OS version?
What is the hardware connection? USB, internal or external Cell modem, etc?
OS 6.01 on remote site, wondering if i can update it by tcp connection, never done that.
the modem is connected by RS-232.
i have an testbench logger with 7.05 now, i'm leaving the same program running to see if OS update will solves the error.
