7-424 SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
7.6 SI I/Os using fail-safe modules connected to PROFIBUS DP
The following function elements will be described using this example:
- Wiring options for ET200S PROFIsafe modules
- Parameterization of ET200S PROFIsafe components (hardware
configuration)
- Parameterization of associated machine data
- Effects on NCK and PLC-SPL
(safe programmable logic).
The entire system with all of the required hardware and software settings is not
shown; rather, only the sections that differ when compared to previous SPL
applications with two separate hardware I/O branches (NCK and PLC I/Os).
7.6.1 Functional scope of the application
The safety-relevant input signals read-in from the F-DI module and processed
in the SPL are to be used to change over axis-specific safety functions (SBH,
SG, external stop response, etc.), and output safety-relevant output signals to
actuators (via an F-DO module or PM-E F module).
7.6.2 Connecting-up the sensors and actuators
The diagram below shows the layout of the ET 200S line-up used in the
example
