Acyclic communication
The inverter supports the following types of acyclic communication:
●
For PROFIBUS:
acyclic communication via data set 47
●
For PROFINET:
acyclic communication via B02E hex and B02F hex
The maximum data length per request is 240 bytes.
Note
Precondition for error-free acyclic communication
•
Use the USB interface of the frequency converter if you use STARTER or SCOUT to
access the device in operation.
•
If you access the frequency converter using STARTER or SCOUT via the interface
module, you must switch the higher-level control into the STOP condition, as otherwise,
faults can occur when executing the tasks from the control system and from
STARTER/SCOUT.
