Registers and module registers
Module registers are the data interface of a JX3 module. Module registers let
you read process, configuration and diagnostics data from the JX3 module, or
write such data to it.
 The module register number within a module is unique.
 This unique register number lets you access a specific module register
within the system.
There are several ways to access registers directly:

Via an application program
 Via a JetSym setup pane
 Via a visualization application
The register number within the system is unique.
The Global Node Number (GNN) is an ID number to identify Jetter controllers
(e.g. controllers, bus nodes) within an Ethernet network.
 The GNN within a network has to be unambiguous for each Jetter device.
 The JetSym Hardware Manager automatically assigns the GNN during
configuration.
 The value range of the GNN within a project is 000 ... 199.
 The controller has always got GNN 000.
Via module register 9 the OS revision of a JX3-AI4 module can be accessed.
A JX3-AI4 module is connected to a controller JC-120MC. The module
number of this module is 2.
