Supported device types and versions

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

Communication line configuration

• Category of communication line: Serial (RS-232 or RS-422), SerialOverUDP Device Redundant
• Parameters of 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 DTR and RTS had to be set to ON, therefore communication line SerialOverUDP Device Redundant with MOXA Nport-5110 converter set to UDP mode could not be used (UDP mode does not support setting DTR and RTS to a fixed value). Instead, the converter NPort-5110 had to be switched to Real COM mode and Serial line had to be configured.

Communication station configuration

• Communication protocol: Alya Gina

• The station address is unimportant.

Station protocol parameters

Communication station - configuration dialog box - "Protocol parameters" tab.
They influence some of optional parameters of protocol.

Table 1

I/O tag configuration

Possible I/O tag types: AI

Addresses of I/O tags:

• NET - net weight of load
• TARA - tare

Note: Providing that a scale sent a message, which means that the platform is not stabilized yet, the values of NET and TARA has an invalid value.
