15.1.5.15 MP Bus Master Module
750-643
The MP Bus Master Module has a total of 8 bytes of user data in both the Input
and Output Process Image (6 bytes of module data and 2 bytes of control/status).
The following table illustrates the Input and Output Process Image, which have 4
words mapped into each image. Word alignment is applied.

®
RF-Transceiver
750-644
The size of the process image for the Bluetooth
®
module can be adjusted to 12,
24 or 48 bytes.
It consists of one control byte (input) or status byte (output); an empty byte; an
overlay able mailbox with a size of 6, 12 or 18 bytes (mode 2); and the Bluetooth
®
process data with a size of 4 to 46 bytes.
Thus, each Bluetooth
®
module uses between 12 and 48 bytes in the process
image. The sizes of the input and output process images are always the same.
The first byte contains the control/status byte; the second contains an empty
byte.
Process data attach to this directly when the mailbox is hidden. When the
mailbox is visible, the first 6, 12 or 18 bytes of process data are overlaid by the
mailbox data, depending on their size. Bytes in the area behind the optionally
visible mailbox contain basic process data. The internal structure of the
Bluetooth
®
process data can be found in the documentation for the Bluetooth
®
750-644 RF Transceiver.
The mailbox and the process image sizes are set with the startup tool WAGO-
I/O-CHECK.
