3 Fieldbus Coupler

3.1 PROFINET IO 750-370

3.1.1 Description

The fieldbus coupler 750-370 maps the peripheral data of almost all I/O
modules in the WAGO-I/O-SYSTEM 750/753 on PROFINET IO.
In the initialization phase, the fieldbus coupler determines the physical
structure of the node and creates a local process image with all inputs and
outputs. I/O modules with a bit width smaller than 8 can be combined to form
one byte in order to optimize the address space.
The diagnostics concept is based on channel specific diagnostic messages that
are mapped to the respective alarms. Coding is done according to IEC 61158
(PROFINET IO).
The bus coupler has the following features:
• Process data length
• Transfer speed of up to 100 Mbit/s full-duplex, also with autonegotiation
• Support of all WAGO-I/O-SYSTEM 750/753 I/O modules
• Configurable data format for each signal channel of complex I/O modules.
• Configurable substitute value behavior for each output module in the event
• Configurable substitute values for each output channel in the event of
• 1 x RJ-45 bus connection
