15.1.5.19 AS-interface Master Module
750-655
The length of the process image of the AS-interface master module can be set to
fixed sizes of 12, 20, 24, 32, 40 or 48 bytes.
It consists of a control or status byte, a mailbox with a size of 0, 6, 10, 12 or 18
bytes and the AS-interface process data, which can range from 0 to 32 bytes.
The AS-interface master module has a total of 6 to maximally 24 words data in
both the Input and Output Process Image. Word alignment is applied.
The first Input and output word, which is assigned to an AS-interface master
module, contains the status / control byte and one empty byte.
Subsequently the mailbox data are mapped, when the mailbox is permanently
superimposed (Mode 1).
