Object Index Subindex Type Default Description
IO – clamp 15
voltage 0x3333 0x66 R32
ro — Terminal 15
Raw value of the analogue input measure-
ment (Volt)
IO – clamp 15
(ignition) state 0x3333 0x01 U8
ro — Terminal 15
0 = input signal low (< 2.5 V)
1 = input signal high (> 5.5 V)
IO = digital out-
put 0x3333 0x0F U8
rw — Pin 7 of the 14-pin Micro Timer II connector
Bit 0: (0 = output signal low, 1 = output sig-
nal high)
Bits 1...7: reserved, set to 0
IO – digital out-
put status 0x3333 0x10 U8
ro — Pin 7 of the 14-pin Micro Timer II connector
Bit 0: (0 = output signal error, 1 = output sig-
nal OK)
Bits 1...7: reserved, set to 0
IO – device tem-
perature 0x3333 0x0E S16
ro — Device temperature in °C
The device can send this data via the CAN interface. The configuration is made via the following
objects:
Object Index Subindex Type Default Description
CANMode 0x4001 0x02 U8
rw — Bit 0: compatibility mode with device
CR3114 (1 s cycle)
Bit 1: forward device status via CAN bus (1 s
cycle)
Bit 2: forward complete GNSS data via CAN
bus (1 s cycle)
Bit 3: forward input/output data via CAN
bus (1 s cycle)
Bit 4: forward acceleration and gyroscope
data via CAN bus (100 ms cycle)
IO BaseID 0x4005 0x05 U16 0x400 COB ID start address for input/output data
transmission (1s cycle)
The exact index and subindex can be found in the corresponding EDS file.
All data available in the respective device mode are sent via the CAN1 interface.
The data of the input/output functions are mapped to the following CAN messages:
COB ID Start byte
Length
(bytes)

IO 0x00 0 4 R32 IO – clamp 30 voltage
4 4 R32 IO – clamp 15 voltage
IO 0x01 0 4 R32 Analogue input 1
4 2 S32 IO – device temperature
4.5 Accelerometers and gyro sensors
The accelerometers measure acceleration along the X, Y and Z axes. The 3-axis gyro sensor
determines the angular velocity on the X, Y and Z axes. This data is evaluated and can be forwarded
to the controller via CAN bus.
