CANio 500 Quickstart Manual, version 1.3
5.1.8 Analog inputs
The CANio 500 transmits the values of the analog inputs 1-4 with the following
CAN message:
CAN identifier
Data field (length = 8)
Byte 0/1
Byte 2/3
Byte 4/5
Byte 6/7
0x280 + node number of the
CANio 500
Saved configuration
:

input 2:

The analog inputs are polled cyclically.
The read values are not analyzed or processed.
The values of the analog inputs are transmitted if at least one value of the ana-
log inputs has been changed by its delta value or at the latest after 500 ms.
The conversion between the raw value and the physical value is described in
section 4.6.
Factory setting:
Delta value for every input: 10 (0x0A)
All inputs are read every cycle of the CANio 500
5.1.9 Value of the power supply PWR(+)
The value of the power supply PWR(+) is transmitted with the following CAN
message:
CAN identifier
Data field (length = 2)
Byte 0/1
0x380 + node number of the
CANio 500
Saved configuration
:
saved identifier
Value of the power supply PWR(+)
:
see chapter 4.7
LSB first
Note for „Value of the power supply PWR(+)“
:
It is a 16
– bit value
Only the lower 12 bit are relevant
The conversion from raw to physical value is described in chapter 4.7
