Supported device types and versions

This protocol is used to read the weighted values from scales produced by ALYA Poprad. It can be used only when a single scale is connected to a line since it does not contain addressing of the scale.
For communication with more scales, 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, the DTR and RTS signals had to be set to ON, therefore the SerialOverUDP Device Redundant communication line together with a MOXA NPort-5110 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 MOXA NPort-5110 serial server had to be switched to a Real COM mode and a 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 the optional parameters of the protocol.

Table 1

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: If a scale sends a message, which means that the platform is not stabilized yet, the NET and TARA I/O tags will have invalid values.
