ION
ION is the native protocol and architecture of your meter.
The basic building blocks of ION architecture are the ION modules, each of which
is specialized to perform a specific task and contains data and instructions on how
to manage that data. ION modules are combined (linked) together to create the
meter’s functions and features. ION modules that are linked together to perform a
specialized task are called a framework, such as the Power Quality framework.
These different functional frameworks are then grouped together to define the
entire meter, and are collectively referred to as the device template.
Your meter ships with a default device template which provides extensive
capabilities. You can also configure your meter’s template to modify your meter’s
existing functions or to create new functions.
See the ION Reference, available from www.usa.siemens.com/pds for further
information about ION architecture and a detailed description of the different ION
modules. See the ION Device Template Reference, available from
www.usa.siemens.com/pds, for details on the modules and their configuration in
your meter’s default template.
Modbus
Modbus is a master/slave communications protocol where the master initiates
transactions and the slave(s) responds with the requested information or action.
Your device can function as a Modbus slave or Modbus master, depending on
how it is configured. Your device comes with Modbus slave functionality
configured and ready to use. You can add custom Modbus information to the
default Modbus slave data provided by your device.
