Depending on the machine configuration (1 or 2 gantries) the one wire bus structure in PA2 is iden-

tical with that in PA1.

1.11.1.3 One Wire Bus in the Siplace X

With the Siplace X-machine the One Wire Bus is integreted in a separate CAT5 cabel, which start

from the Main- and Subdistributor up to the trailling interface. From the trailing interface up to the

head interface the one wire bus goes through the trailling cable. So that the cable structur are dif-

ferent but not the function of the one wire bus. 1

Depending on the machine configuration (1 or 2 gantries) the one wire bus structure in PA2 is iden-

tical with that in PA1.

Function description: 1

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 Trouble-

shooting for Service Work).

One wire bus components 1

Assemblies:

1. 1 wire RS232 bridge on the SUB/MAIN module (to be later integrated into the I/O module)

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

3. 1 wire CAT 5 Splitter

4. 1 wire hub for nozzle changer

5. Control board for nozzle changer (integrated into NC, not for DLM heads)

6. 1 set of temperature sensors (replacement only as a set, due to serial number)

7. EEPROM for gantry recognition
