1.11.3 One wire Bus Siplace X machine
The structure of the One Wire Bus Siplace X was changed in opposite the HF/HF3 machine.
With the new hardware structur of the bus system the allocation of subsystems to the hardware
components is different (see table).
Attention: New Application on the I/O moduls necessary! (BIOS E0100323, Application E0110350
or higher)
During the initialization procedure all subsystems send a message via the public byte by yourself.
The public byte comes from each subsystem of the machine via the CAN ID +3hex. If the state of
a subsystem changes, the subsystem reports automatically and without request of the application.
