CANopen indices for mapping
According to the CANopen specifications, the indices I−160x and I−1A0x are available for
mapping the CAN PDOs. During mapping, the process output data of the master are
mapped via the indices I−160x to the AIF input data of the basic device. The indices I−160x
refer to codes C1822 and C1824. The entry contains the index of the corresponding code
and the corresponding subindex for the assignment of a word or double word. The object
length must be indicated accordingly.
Under the indices I−1A0x, the indices of code C1823 must be entered for words or the
indices of code C1825 for double words.
Device−internal mechanisms
The user must know the AIF interface assignment to configure the mapping accordingly in
the communication module. All data of the AIF interface can be placed on any position of
the CAN PDOs. The maximum scope of the AIF interface is shown in the codes. The available
values depend on the basic device and on the application in the basic device.
