9.3.2 Acyclic data transfer

[9-3] Transmission directions

Explanation

• A "Write.req" is used to pass the data set (DB47) to the slave in the form of a parameter request.

• With "Write.res" the master receives the confirmation for the receipt of the message.

• The master requests the response of the slave with "Read.req".

• The slave responds with "Read.res (-)" if processing has not yet been completed.

• After parameter processing, the parameter request is completed by transmitting the parameter

response to the master with "Read.res (+)".

 Note!

A parameter request refers to one or several parameter(s) (multi-parameter request).
