13.3.5.16 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).
In the operating mode with suppressible mailbox (Mode 2), the mailbox and the
cyclical process data are mapped next.
The following words contain the remaining process dat.
The mailbox and the process image sizes are set with the startup tool WAGO-
I/O-CHECK.
