FTPClientActivePort
Specifies the inclusive lower bound of a range of 1,000 TCP ports that the datalogger uses to listen for FTP data connections when the FTPClient instruction is operating in Active Mode. Each call to FTPClient will use the next available port in the range, wrapping back to the beginning after reaching the last port. For example, if the value 48000 is specified, ports 48000 through 48999 will be used. Default value is 48000.
