This protocol enables is used to read the weighted values from scales produced by ALYA Poprad. It can be used only when connecting one a single scale is connected to a line , since it does not contain an addressing of the scale.
For communication with more scales, you may use the ALYA SPOOL protocol may be used.

Communication line configuration
...
- Category of communication line: Serial (RS-232 or RS-422), SerialOverUDP Device Redundant
- Parameters of the serial line:
- Baud rate: 2400 Baud
- 8 data bits
- 1 stop bit
- Parity: Odd
Note: to get the communication started with a specific device, signals the DTR and RTS signals had to be set to ON, therefore communication line the SerialOverUDP Device Redundant communication line together with a MOXA NportNPort-5110 converter serial server set to the UDP mode could not be used (the UDP mode does not support the setting of DTR and RTS signals to a fixed value). Instead, the converter MOXA NPort-5110 serial server had to be switched to a Real COM mode and a Serial line had to be configured.

Number call some in communication I/O tag configuration
...
Possible I/O tag types: AI
Addresses of I/O tags:
- NET - net weight of the load
- TARA - tare - the weight of the packaging
Note: Providing that If a scale sent sends a message, which means that the platform is not stabilized yet, the values of the NET and TARA has an invalid value I/O tags will have invalid values.
