4.3 Module
Numbering
At numbering the modules at the Jetter system bus, the I/O module number and the slave
module number are differentiated. The module number is part of the coding for input and
output numbers, as well as for the register numbers of the expansion modules, which are
connected to the Jetter system bus.
I/O Module Number
An I/O module number is not assigned to all non-intelligent JX2 modules and all JX3
modules. I/O module numbers are assigned according to the following rules:
•
I/O module number 1 is always assigned to the controller.
•
I/O module number 2 is assigned to the first non-intelligent JX2, respectively JX3
module connected to the Jetter system bus.
•
The modules JX2-PS1 and JX3-PS1 are not counted.
•
Intelligent JX2 modules are not counted.
•
The first JX3-BN-CAN connected to the Jetter system bus is assigned to I/O module
number 33.
Slave Module Number
A slave module number is assigned to all intelligent JX2 modules and JetMove motion
systems. Slave module numbers are assigned according to the following rules:
•
The controller is always assigned to slave module number 1.
•
The first intelligent JX2 module connected to the Jetter system bus is assigned to
slave module number 2.
•
Non-intelligent JX2 and JX3 modules are not counted.
Example: Module Numbering
In this example, various expansion modules have been connected with a JC-24x. The I/O
module numbers are shown above, the slave module numbers below the modules.
