TCP/IP Channel:

Node Connections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)

Serial Channel:

Configuration for the AA communication protocol: 

• • Station syntax: <Address>
  • Where:

<Address> = Device address in the network (01-99)   

E.g.: 03

Configuration for the TRC communication protocol:

• • Not used for this protocol. The Driver will receive every message from the network. 

TCP/IP Channel:

• Station syntax: <IP address>;<Port number>;<Address>
• Where:

<IP Address> = IP address of the scale in the Modbus network

<Port Number> = TCP port where the device is listening

<Address> = Device address in network (01-99)   

E.g.: 192.168.1.101 ; 502 ; 1

The syntax for the Alfa communication points is:  <Type>

Where:

<Type> indicates the part of the message that will be stored in the configured Point

The valid types are:

• Tare: Returns only Tare value
• Weight: Returns only Weight value
• Return: Returns full message

E.g.: For a typical message like ’PB: 00,254kg T: 00,000kg’, each Point shown in the above table will receive the following data:

Scale1 FullMessage= PB: 00,254kg T: 00,000kg

Scale1 Weight= 00,254kg

Scale1 Tare= 00,000kg
