8.4.1 Numbering registers and I/Os
Module registers -
Definition
Module registers are the data interface of the expansion module. Module regis-
ters let you read process, configuration and diagnostics data from the expansion
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.
Access options
There are several ways to access registers directly:
■
From an application program
■
From the JetSym setup pane
■
From a visualization application
The register number within the system is unique.

Expansion modules connected with a controller
Our products offer a host of functions which can be accessed by the user via reg-
isters. Every register has got an unambiguous number, the register number. Each
digital input or output has got an unambiguous I/O number.
Register numbering system
Register numbers consist of a prefix, the module position in the system and the
module register number. If the expansion modules are connected with the con-
troller via JX3 system bus, the prefix is 100. In this case, the module register
number is always a four-digit number.

I/O numbering system
The inputs or outputs of the module are directly accessed via I/O numbers. These
I/O numbers consist of a five-digit prefix, the module position in the system and
the I/O number of the module. The I/O numbers always start with the constant
prefix
