Slot Number and Slot Index
Used in the slave to address the desired data block.
Length
This parameter specifies the number of bytes to write. If the destination data
block size is less than requested, the response will contain an error message. If
the data block length is greater than or equal to the requested length, the
response contains the number of bytes that have been written. The slave may
answer with an error response if data access is not allowed.
Data [1 … n]

4.2.8 Mailbox Message: Alarm Indication
This message indicates to the application that a DPV1 slave has transferred an
alarm message to the Master. This mailbox message is sent spontaneously by
the module; the module itself initiates the mailbox communications.
Detailed information about the cause of the alarm is presented in extended words
1 to 3 and in the message data field (see below).
