Documentation of the mapping parameters is given in the POWERLINK specification. You can find it on [http://www.ethernet-powerlink.org/][1] in the section Downloads -> Documents -> Communication Profile Specification, section 6.4.9.
In your example, you are just missing to adjust the bitoffset in the PDO, i.e. the position at which the object data should be put into the frame. (Usually...

Yes, the procedure is correct. Note that the X20AO4622 and the X20AI4622 have both got 4x16bit channels, so in order to use all channels you need to map 8x 0x6401 and 4x 0x6411.
Example for the Rx-Mapping:
0x1600/0x00 = 0x00 // Disable the mapping
0x1600/0x01 = 0x0008000000016200 // Map 8 bits of 0x6200/0x01 to bit-offset 0 of the PDO
0x1600/0x02 = 0x0010000800016411 //...

Hi Anders,
While reconfiguring the mapping parameters, the current mapping must be deactivated by setting 0x1600/0 (or 0x1A00/0) to 0. Then, the parameters can be put into the subindices, and finally the mapping is re-activated by setting the correct number of parameters into subindex 0.
In your case this means:
<ul>
<li>Write 0 to 0x1600/0</li>
<li>Write...

On the MN side (i.e. in the application) the mapping is done correctly. This is reflected by the data in the PReq packets.
But also the CN needs its mapping. In the Qt demo only the cycle time (0x1006) is written to the CN. Additionally, you have to send mapping parameters via EplApiWriteObject.
To activate the digital inputs and outputs, the following settings on the CN are necessary:

Hello Anders,
The BC0083 can work in DS401 mode. To enable this, just reset it to its defaults by writing 'load' to 0x1011/0x01 and restart the BC.
The inputs/outputs can be accessed via sub indices of the following objects:
0x6000 (DI), 0x6200 (DO), 0x6400 (AI - 8 bit), 0x6401 (AI - 16 bit), 0x6402 (AI - 32 bit), 0x6410 (AO - 8 bit), 0x6411 (AO - 16 bit), 0x6412 (AO - 32 bit)

Hi Regina,
On a CN, the timers are needed e.g. to monitor the operation of the MN. That means that the CN will fall back to a PreOperational state if it does not receive requests from the master after a given time (configurable threshold values)
Regarding the Ethernet driver: Have you got a more precise question to the implementation? What problems are you facing at the moment?
Out of...
