Mailbox Mode - WAGO I/O SYSTEM 750 750-671 Manual

2.1.2.8

Mailbox Mode

The mailbox expands the application range considerably.
The mailbox is activated when bit 5 of the control byte C0 is set to 1.
Activation of the mailbox is acknowledged by bit 5 of the status byte S0.
Note
The Mailbox mode is not selected automatically when the mailbox is activated
in the coupler/controller! Bit 7 of control byte C1 must be set to 1 for this.
2.1.2.9 Table Manager
Access to the tables is handled using the Table Manager. Possible types of
tables:
 Move programs,
 Positioning of camshaft,
 Target positions,
 Configuration,
 Data recorder.
Several tables may exist at different storage locations for one type of table.
The storage location is addresses using an index.
Index Storage location
0:
1:
2:
Exceptions to this are: Configuration and the data recorder use RAM1
exclusively. The data from the data recorder can not be copied to the
EEPROM.
One table of each type of table can be activated and this is then evaluated in
the Move mode.
One table of each type can be saved to the EEPROM. Tables in the EEPROM
can not be activated, but only copied to a RAM table. If a table is present in
the EEPROM, it will be copied automatically to RAM1 and RAM2 following
a reset and is activated such that it can be directly executed in RAM1.
The tables are loaded from the control system by download. The following
rules apply to downloading:
