You can calculate the exact amount of connectable expansion modules by
means of the JX3-sysbus_configurator_xxx_e which is available for download
from our Homepage.
For more information on this subject refer to the application-oriented manual
"JX3 System" available for download on our website.
You can also use the JX3-BN-EC in combination with a controller that was not
developed and produced by der Jetter AG. See also

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.
