3.1 Set up and configuration with WAGO-I/O-CHECK 2
In order to work with the AS-Interface master module 750-655, first set up the
communication connection to your node. Then read out the node configuration
and select the required module in the navigation screen or node view.
Next set the required process data and mailbox length in the parameter setting
dialog.
After this, you can set up the required operating mode for the master in the
process data dialog or select a slave for further processing from the list of
slave addresses.
Use the diagnostics function in order to correct configuration errors.
3.1.1 Setting up the AS-Interface process data and mailbox length
Open the parameter dialog for the selected bus module. To do this, click on
the Settings command in the context menu for the module (node view or
navigation).
The size of the internal bus process image is specified with the Process Image
Length selection box. You can choose values of 12, 20, 24, 32, 40 or 48 bytes.
The size of the mailbox is specified with the Mailbox Length selection box.
You can set values of 0, 6, 10, 12 or 18 bytes.
Note:
If a mailbox length of 0 bytes is selected, it will only be possible to display
process data for digital slaves in monitor mode. Process data cannot then be
displayed or set up in control mode.
The Overlapped Mailbox selection box is used to determine whether the
mailbox data are overlapped with the AS-Interface process data (selection box
activated) or whether the AS-Interface process data are transmitted after the
mailbox data (selection box not activated).
The available combinations of options correspond to the configurations that
can be set up using the Profibus or CANopen type files.

displayed values can then be further modified.
