2.3.2 User data
Three different data types are transferred via the user data area of the CAN telegram:
Data type Info
Network management data Establishing communication via the CAN network. Chapter 2.4 ( ^ 2-5 )
Process data Process data are used in control technology, e.g. setpoint and actual
values.
•
Process data are high-priority data that are transmitted as so-called
PDOs
(
Process Data Objects ) via the CAN network.
•
The PLC processes process data quicker than parameter data.
•
Special system blocks or free CAN objects are used to transmit and
receive process data:

Free CAN objects The functions/function blocks of the
LenzeCanDrv.lib function library can be used to add so-called
“free CAN objects” to the permanently integrated CAN objects.

Parameter data
With Lenze devices ”codes” are parameter data.
•
Parameter data are, for instance, set when the plant settings are made
during commissioning or when the material for the production machine
is changed.
•
Parameter data are transmitted as so-called SDOs ( Service Data
Objects ) via the CAN network and acknowledged by the recipient, i.e.
the transmitter receives a message whether the transmission was
successful.
