9.5.2 Write mode
• Acyclic write request from master to slave:
• Response from slave to master is OK:
• Response from slave to master has failed:
• After the acyclic write request (index 0x13 (19)) has failed, the master sends error codes.
• Then the write request from master to slave with the index 0x29 (41) is repeated.
• The slave sends the parameter values in code C13213/1...16
again.
