CO4011A-FL
Single Chip CANopen Controller for Remote I/O
Index 5003 : Filter Time Digital Input
The CO4011A offers noise filtering for each digital
input line. With object 5003 an individual filter time
may be assigned to each input line.
The filtering function enable object is at index 6003h.
The filter time is set in milliseconds. A value of 0
disables the filtering function.

Index 6000 : Read Digital Input 8 Bit
This object represents the digital input bytes. The
value of the input lines is written to this object.
Before writing the level of the input lines to object
6000, the input data is processed in the following
way:
1) The digital input lines are active low. This
means, the input level is inverted at first.
2) At the next stage, the CO4011A processes the
filtering function. Object 5003 gives the filtering
time and object 6003 enables or disables the
channels.
3) Then the input lines are inverted again
according to the setting of object 6002h (polarity
input)
4) At last the debug function calculates a logical
OR conjunction between the input lines and
object 5001 and a logical AND with object 5002
and then writes the result to object 6000h
The number of digital input bytes depends on the
selected operation mode.
The mapping of the I/O lines to object 6000 is ex-
plained in chapter "Mapping I/O to Object Dictionary"
