WAGO AS-Interface Master
750-655
The image process size for the AS-interface master module is adjustable to 12, 24,
32, 40 or 48 bytes. It consists of a control or status byte, a mailbox with 0, 6, 10,
12 or 18 bytes and 0–32 bytes of AS-interface process data. The AS-interface
master module occupies 12–48 bytes in the process image.
The first byte contains the control/status byte, the second contains an empty byte.
Subsequently, mailbox data is mapped when the mailbox is permanently
superimposed (Mode 1). While in operating mode with a suppressible mailbox
(Mode 2), the mailbox and the cyclical process data are mapped next. The
remaining bytes contain the remaining process data.
