The fieldbus couplers for PROFINET link the WAGO-I/O-SYSTEM to the PROFINET IO, the open industrial ETHERNET automation standard.
The fieldbus couplers for PROFINET map the peripheral data of all the I/O modules of 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).
Configuration (via GSDML files), as well as operation and diagnostics, can occur completely via the master interface's standardized tools.
The master writes configuration and parameter data permanently into the coupler, permitting hardware exchange without intervention in the software.
Fail-safe I/O modules (750, 753 Series) enable applications up to SIL3 according to the PROFIsafe V2.0 specification.
The configuration of placeholder modules, and the start-up of hardware configuration that deviates from the project planning, is provided for all couplers. Standard-compliant diagnostics provides detailed information about the coupler and module status.
The error behavior of I/O modules can be individually parameterized in preparation for communication failures. Integrated switches permit the implementation of a line topology.
