7.1 Addressing within the system

JX3-BN-EC User Manual
Each JX3 I/O module has over 10,000 local module registers and, depending on
the module type, a certain number of digital inputs and outputs.
These local module registers and I/Os are mapped to register numbers and I/O
numbers in the controller. These numbers let you read and write process, config-
uration, and diagnostic data of an expansion module. These numbers can be ac-
cessed in the application program of the controller, in a setup pane of JetSym or
via user interface.
The number of a controller register to which a module register has been mapped
is influenced by the following parameters:
■ Controller model
■ Type of connection between controller and expansion module
■ Direct connection to a local controller or expansion module
■ Remote connection via Ethernet
■ Remote connection via EtherCAT
■ Position and amount of expansion modules in the system
The amount of expansion modules which can be connected to a controller de-
pends on the type of the expansion module. After 8 expansion modules max.,
a power supply module must be inserted.
