    27 12. Point configuration as mentioned in section 1, the network gateway series concept revolves around a central “point database”, containing various individual points. A “point” is simply an object that defines some sort of primary -to- secondary network mapping information. In the case of the dn...

    28 12.1 parameter configuration as previously mentioned, each data item residing on secondary-network devices must be mapped to a unique devicenet parameter object to allow access via the devicenet network. This access may take place directly via explicit messaging, or indirectly via i/o messaging. ...

  • Page 30

    29 in order to allow the tool to access the modbus devices, we must define a devicenet parameter for each of the objects (secondary network modbus registers) that we wish to access. Let’s assume that the data shown in table 3 is to be accessed on each of the respective modbus devices, and that the d...

Explicit messaging). N...
