Communication
A.1 Communication
When you create the configuration on the controller side (e.g. HW Config), the process-data-
capable drive objects for the application are added to the telegram in the shown sequence
(see above).
The following drive objects can exchange process data:
● Active Infeed (A_INF)
● Basic Infeed (B_INF)
● Control Unit (CU_S)
● ENC
● Smart Infeed (S_INF)
● Terminal Board 30 (TB30)
● Terminal Module 15 (TM15)
● Terminal Module 31 (TM31)
● Terminal Module 150 (TM150)
● VECTOR
Note
The sequence of drive objects in HW Config must be the same as that in the drive (p0978).
Drive objects after the first zero in p0978 must not be configured in the HW Config.
The structure of the telegram depends on the drive objects taken into account during
configuration. Configurations are permitted that do not take into account all of the drive objects
that are present in the drive system.
Example:
The following configurations, for example, are possible:
● Configuration with VECTOR, VECTOR
● Configuration with A_INF, VECTOR, TB30
● etc.
Communication channels for PROFINET
PROFINET connection channels
● A Control Unit has an integrated Ethernet interface (X127).
● The PROFINET version CU320-2 PN features a PROFINET interface (X150) with 2 ports
onboard: P1 and P2
● The control can simultaneously establish a total of 8 acyclic connections (e.g. S7) via the
integrated PROFINET interfaces.
