9 Parameter data transfer
Parameter data are transmitted via the fieldbus as SDOs (Service Data Objects). The SDO
services allow for the writing and reading access to the object directory.
ƒ Via the SDO channel, access to all implemented CoE objects (
¶ 55) and Lenze codes
(
¶ 57) is enabled with the CoE protocol.
ƒ When a "CiA402" technology application is used in the controller, the access to all
implemented CANopen CiA402 objects is enabled.
ƒ The transmission of parameter data usually is not time−critical.
ƒ Parameter data for instance are operating parameters, diagnostic information,
motor data.
9.1 Connection establishment between master and slave
Basically a master can always request parameter requests from a slave if the slave is at
least in the "Pre−operational" state.
