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).

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
