Four groups of LIN signal frames are defined to control the dedicated
axis:
•
Axis 1_1 (to be used as horizontal axis, right lamp) signals group
•
Axis 1_2 (to be used as horizontal axis, left lamp) signals group
•
Axis 2 (to be used as vertical axis, right lamp) signals group
•
Axis 3 (to be used as vertical axis, left lamp) signals group
The reconfiguration of the LIN signals (see above) means that the slave
can be programmed to be active only on one of the four signal groups
(so it ignores signals for other actuators). This signal group can also be
chosen from the LIN-bus master with the LIN-bus configuration signals
(Master Request and Slave Response frames). The benefit of this
solution is that there can be one universal controller software for any axis
actuator. It can then be configured via LIN-bus for any axis, as required.
2.3 LIN Master
The function of the master board depends on the selected mode, chosen
by means of a jumper on the board (see
).
The modes are as follows:
•
PC master mode (PCM)
•
Master mode (M)
•
Debug mode (D)
•
Pass mode (P)
