All test communicates must be positive for the correct operation of the MIDL<br />

data logger. The window contains also network configuration parameters that are<br />

necessary to know for establishing connection with the system.<br />

11.5. Configuration of basic parameters of the MIDL system<br />

The correct operation of the system needs initial configuration of the Internet<br />

link. The configuration parameters are included in a system file ”server.ini”<br />

located on the MMC memory card. This file may be placed in the MIDL data<br />

logger in three ways:<br />

− writing on the MMC card by means of an universal read/write device<br />

dedicated for MMC memory cards, connected to a PC computer, inserting<br />

the card into the slot in the MIDL device (MASTER or SLAVE) and<br />

switching on the power supply,<br />

−<br />

−<br />

accessing the cart in the device slot by WWW site,<br />

accessing the cart by means of FTP protocol to send the “server.ini” file<br />

by Internet.<br />

Before accessing the card by WWW browser or FTP client the device must be<br />

connected to the computer by means of IP network.<br />

11.6. System files<br />

There is a number of file types in the MMC memory card. From a WWW site<br />

it is possible to access script files (“*.scr” file extension) and output data files<br />

(“*.txt” file extension). All files on the MMC memory card are accessible by FTP<br />

client or by reading the card in the universal card reader read/write device:<br />

− files with „*.htm”, „*.css”, „*.js” extensions – files of graphical user<br />

interface used by a WWW browser,<br />

− files with „*.scr” extensions – device executable script files,<br />

− files with “*.txt” extension - output data files generated by executable<br />

scripts,<br />

− files with “*.ini” – system files with the device configuration parameters.<br />

The format and command of the executable script files are presented below.<br />

11.7. Executable script files<br />

Files with „*.scr” extension treated by the device as executable script files.<br />

Table 17 below presents an example script file with commands that: fix the<br />

SLAVE RS232C serial port transmission speed to 9600 baud, give a name to the<br />

output data file where the data from the addressed sensor will be stored, send a<br />

command to the serial RS485 interface with the address activating the individual<br />
