CO4011A-FL
Single Chip CANopen Controller for Remote I/O
Index 6401 : Read Analog Input 16 Bit
Object 6401, represents the value of the analog
channels. The 16 bit conversion result of the analog
input voltage is a signed value. Therefore voltages
less then 2.5V are read as negative input voltage. An
input of 2.5V is read as 0 and an input voltage higher
than 2.5V is converted into positive values.
If the application requires reading of the analog input
voltage as unsigned values, the object 6431 may be
used for adding an offset to the conversion result.
The mapping of the I/O lines to object 6401 is ex-
plained in chapter "Mapping I/O to Object Dictionary"
Note:
Object 6401 is only valid if operation mode
selects 16 Bit resolution of A/D converter.

Index 6421 : Analog Input Interrupt Trigger
Object 6421 selects the event that shall cause a
transmission interrupt for the selected analog
channel.
There is one Subindex for each channel to enable
individual setting according to application require-
ments.
