JX3-BN-EC User Manual
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.

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 10000.
