6 Byte Mailbox

In the "6-byte mailbox" operating mode the HART module provides the fieldbus
coupler/controller with a 12-byte input and output process image via one logical
channel.
1 control byte (C0) and 1 status byte (S0) are used to monitor the data flow.
The data is mapped in the cyclic process image of the connected
coupler/controller. However, the HART commands can then be implemented by
the "WagoLibHart_0x.lib" PLC library. The data is tunneled to the application via
a mailbox and decoded by means of the library so that evaluation and processing
take place directly at the application level.
The IEC application can be implemented in the connected programmable
fieldbus controller (PFC) of the fieldbus node with the WAGO-I/O-PRO
programming tool or, if a fieldbus coupler is connected, in the superimposed
controller.
