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..

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.

Function Description

4.5.1.3 Function Description

When the machine is switched on, each one wire bus is assigned a fixed CAN ID.

One wire in PA1 --> CAN ID: 07d0

One wire in PA2 --> CAN ID: 07c0

During initialization of the bus system, each station registers with the master, after which the bus is ready

for operation.

In the non operative mode, the voltage level is 5 V on the one wire bus.

A repeat initialization can be performed with the CACCIA tool (see Function Control and Troubleshooting

for Service Work).

One Wire Bus Components

4.5.1.4 One Wire Bus Components

Assemblies:

1. Interface 1-Wire CAT5 on the SUB/MAIN module

2. 1 wire CAT 5 Gantry on the trailing interface (board between CAN bus and trailing interface)

3. 1 set of temperature sensors (replacement only as a set, due to serial number)

4. EEPROM for gantry recognition

Interface 1-Wire CAT5

Interface 1-Wire CAT5 on the SUB/MAIN module (version 02) [03041578-01]

4. Temperature sensors gantry 4

5. NC row 1 gantry 2/4

6. NC row 2 gantry 2/4

7. 24 V

8. GND

For initial analysis, the 5 V level can be measured at the

1-Wire-CAT5 connector of the interface.

The 24 V at pin 8 can be measured at the old 1-Wire and

serves as voltage supply for the nozzle changers. The

24 V are fed into the 1-Wire distributor. However, this is

not used at the interface.
