Id-Net Multidata Network (Pass-Through) - Datalogic Matrix 320 Product Reference Manual

TYPICAL LAYOUTS

ID-NET MULTIDATA NETWORK (PASS-THROUGH)

A special case of the pass-through layout allows each Slave device working Alone, to
collect data from one or more pass-through input channels and send this data plus its
own on the ID-NET output channel to the Master.
The Slave readers are connected together using the ID-NET interface. Every Slave reader
must have an ID-NET address in the range 1-31.
The Master collects the data from its pass-through ID-NET input channel and sends it to
the Host on a different output channel.

Pass-through Input Channel
Output Channel
In a Pass-through layout each device supports multiple pass-through configurations to
accept input from different devices on different channels (i.e. Master reader above). How-
ever, ID-NET Slave readers are not required to have a pass-through configuration if they
don't need to receive data from an input channel (i.e. right reader above). The ID-NET
Master always has at least one pass-through configuration to collect the ID-NET Slaves
data and send it to the Host.
NOTE
All devices always support multiple output channels (i.e. for data monitoring).
In a Pass-through layout each device can have a different operating mode: Continuous,
One Shot, Phase Mode, etc.
