CO4011A-FL
Single Chip CANopen Controller for Remote I/O
Index 6431 : Analog Input Offset
Object 6431 adds an offset value to the analog input
data object (6400 / 6401).
The normal input scaling for analog data objects
6400 and 6401 considers conversion of negative
input voltages (input amplifier must shift to positive
voltages because input port pin is 0 to 5V only) by
placing the zero point (of data) to 2.5V. (middle of
input voltage range)
If application requires only positive input values an
offset may be add with object 6431, in order to adjust
the zero point for data to an input voltage of 0V. For
8 Bit analog conversion (object 6400) the offset
value (object 6431) must be 80h. For 16 Bit analog
conversion (object 6401) the offset value must be set
to 8000h.

Power Down Control Objects
For control of the Power-Down-Mode several objects
are applied in the object dictionary of the CO4011.
Index 2FF9 : Power Down with Stop Node
This object enables switching the device to power
down state by using the NMT command stop node.
This feature is enabled by writing the value
0x454E534E ("ENSN") to this object and additionally
object 2FFE (“Enable Power Down”) must be set
with the valid signature. As soon as this two
signatures are set, the Stop Node Command will
switch the Chip to Power down mode.

Note:
Using the NMT command STOP NODE for power

CANopen draft standard.
Index 2FFA : Wake-Up-Confirm-Time
Wake-Up-Confirm-Time
The CO4011 switches to the active run mode after a
wake up event by pin WUII (Wake-Up-Interrupt-
Input).
If it doesn’t receive a valid NMT telegram during the
Wake-Up-Confirm-Time, so it automatically switches
back to the Power-Down-Mode.
The time is given in milliseconds.
The access is done by SDO.
