okay now this is making sense:  you CAN NOT read more characters then your buffer.  You're reading into 'buff' which is only 128 characters long, so either make your buffer bigger or use a loop to read chunks.

use: fread(buff, sizeof(char), len, pFile) also there is no fopen() call in your code, and you need this also.

It sounds like you didn't upgrade the firmware on your smart server (you just installed the new software on your computer).  i expect when you upgrage the firmware on the e4 it will run your FPM just fine.

Nope there's not (nothing standard anyway).  Hopefully it will be added to the next release. I also needed to do this for one of my projects, and I found several functions that should have worked with VxWorks and FPMs (and even compiled).  Unfortunately when I loaded the FPMs to a SmartServer, they wouldn't start due to ...

It should be using a SOAP call.  You could try a tool like Charles to isolate the messages.

Hello Richard, It sounds like you are working on a very intriguing challenge, and I would be very interested in your results (and source code). I'm also curious about the SmartServers capacity and capabilities, specifically its' ability to handle multiple FPMs and large amounts of data points, so it would be ...

I've been trying to use the List() function with xSelect in an FPM application, and I haven't quite figured it out yet.  The SmartServer Programmer's Reference (document# 078-0347-01A) has some good examples on page 24.  You might want to try the ...

Hello SmartServer Users, I got a TCP/IP socket going today (hooray!).  The functions I was searching for turned up here: #include <arpa/inet.h> //For sockaddr_in and inet_addr() #include <sockLib.h> //For socket(), connect(), send(), and recv() If anyone knows a better way to use sockets with SmartServers I'd still love ...

Hello SmartServer Users, The FPM User Guide explains read/write methods for the RS-232 and RS-485 ports, but I've heard a very reliable rumor that FPM Drivers can also be used for reading and writing to the Ethernet port (i.e. sockets).  My question is can FPM Drivers support sockets (or an equivalent)?  The socket.h ...
