58 Process Image WAGO-I/O-SYSTEM 750750-644 Bluetooth® RF-TransceiverManualVersion 2.0.0, valid from FW/HW Version 03/03A detailed description of all Mailbox commands is available in the appendix.6.3.2 Process Data Overlaid by MailboxIf the Mailbox is mapped, it overlays part of the process data based on itsconfigured size. In “Ad-hoc Communication” and “Real-Time Communication”modes, other process data may not be valid. Such is the case when the processdata of a slot is partially covered by Mailbox data.While the Mailbox is mapped, the data of a partially overlaid slot is not updated inthe PII even if the remote device assigned to this slot sends new data.Figure 16: Partial overlay of process data by the Mailbox – PIILikewise, the local 750-644 I/O module does not transmit the remaining data inthe PIO of an entirely or partially overlaid slot to the remote 750-644 I/O module.
