RF transceiver
750-644
The length of the process image of the
Bluetooth
®
I/O module can be adjusted to a
fixed size of 12, 24 or 48 Byte.
It consists of one control byte (input) or one status byte (output), one empty byte,
one 6-, 12- or 18-byte overlayable mailbox (mode 2) and the
Bluetooth
®
process
data with a size of 4 to 46 bytes.
The
Bluetooth
®
I/O module uses between 12 to 48 bytes in the process image. The
size of the input and output process images is 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
