Communication line configuration

...

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 Real COM mode and a Serial line had to be configured.

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.
