* SERCOS:
This property associates an axis with a drive. The actual drive address is set by a DIP switch on the drive. If an axis is to be simulated, the drive address of that axis is set to zero. The association may be set explicitly, using this property, or the association may be set during Sercos communication phase 1, when the Sercos driver scans the ring for drives. You must explicitly ask that the ring to be scanned for drives, using the SERCOS.SCAN property.
* CANOpen:
This property associates an axis with a drive. Usually address is set by a DIP/Rotary switch (located at device/node!) or stored in node's nonvolatile memory.
The association is set explicitly, using this property. Value reflects 7 LSBs in TPDO/RPDO COBID.
softMC will start sending/receiving PDOs only when this property is not zero.
see CANOpen:Setup for details
* EtherCAT:
This property associates an axis with a drive. Reflects physical (topology) position of the device (node) on the network, that's, first device has address 1, second is 2 and so on.
Fist device is the device that is connected to the softMC EtherCAT port.
The association is set explicitly, using this property.

see EtherCAT:SETUP-EC for details
