4.4.3.3 SIPLACE Diagnosis Adapter A364 [03051220-01]
Application:
The adapter card is used to check the A364 axis card dynamics.
The A364 axis card is equipped with two processors (module 1 and module 2) i.e. one processor controls
two axes.
NOTE:
This adapter is designed for all machines with A364 and as an adapter for the CAN test box with
force measuring tool.

4.5 One Wire Bus
The one wire bus in the SIPLACE X4I is used for requests between the temperature sensors and the
head plates and for reading out the gantry type. The nozzle changer control and sensor requests for the
reject bin are established via a so-called CAN node (see Chapter Component Handling).
Tasks:
1. 2 temperature sensors per gantry (fixed to the head plate).
2. Storage of gantry identification on an EEPROM.
A differentiation is made between plate gantry CFK-02, Design To Cost (DTC) gantry CFK-04 and
CFK 06 gantry. This means that the machine database loaded for the dynamic parameters of the
main axis differs according to the gantry type concerned.
4.5.1 One Wire Bus - Structure
As the name indicates, the data are transferred (serial transfer) via a single wire, to the relevant
subsystem. The one wire bus system is used for processes where time is not a critical factor and can be
realized as a single master bus with „any number“ of slaves (stations).
4.5.1.1 Basic Structure
4-42: One wire bus principle
The one wire bus system consists in principle of a master with EEPROM (control unit), which controls
the various submodules such as A/D converters, EEPROM, temperature and I/O modules. Each
communication branch is equipped with an upstream coupler, which opens the branch for data transfer..

4.5.1.2 One Wire Bus in the SIPLACE X
4-43: Overview of one wire subsystems e.g. PA1 on the SIPLACE X4I
In the SIPLACE X4I machine, the one wire bus is integrated via a separate CAT5 cable, which leads
from the main or subdistributor up to the trailing interface. The one wire bus is run through the trailing
cable from the trailing interface up to the head interface. This means that the cable structure is different
and only the temperature sensors are still monitored. The temperature values are used to calculate the
relevant offset values for placement accuracy.
