Higher-Level Configuration Protocols - WAGO I/O-SYSTEM 750 Manual

Connection with other 750-644 I/O modules in "Ad-hoc Communication"
mode only makes sense in mixed mode!
"Ad-hoc Communication" mode can also be used for communication between
several 750-644 I/O modules. Just like all other Bluetooth
modules must be configured to slot addresses 0x10 ... 0x15. Because the timing
compared to "Real-Time Communication" mode is much worse, the procedure
should only be selected when communication is required with other types of
Bluetooth

Higher-Level Configuration Protocols

Limited description of configuration and parameterization process!
Use register communication, parameter channel and Mailbox for the purposes
described in these instructions only. Improper use of these protocols can cause the
750-644 I/O module to not work as intended.
Use WAGO-I/O-CHECK for configuration and parameterization.
If possible, use the WAGO-I/O-CHECK software to configure and parameterize
the 750-644 I/O module. The software displays all relevant settings for the I/O
module in a graphical user interface and ensures convenient, proper use.
For configuration, parameterization or diagnostics, process data can partially and
temporarily be overlaid with data from one of two configuration protocols, so-
called register communication or Mailbox:
• For register communication, 2 bytes are overlaid as needed. All subsequent
bytes are then invalid.
• The size of the Mailbox can be configured. Depending on the setting, 6, 12
or 18 bytes are overlaid as needed. Subsequent bytes up to the next segment
boundary are invalid.
The possible settings related to the overall process image and Mailbox size, as
well as the impact of mapping the overlaid communication protocol are illustrated
in the following table:
